Sermorelin acetate is a peptide made up of a chain of 29 amino acids. It is commonly referred to as sermorelin and was previously sold under the brand names Geref and Gerel. It is synthesized to resemble endogenous growth hormone-releasing hormone (GHRH) [1].

Sermorelin works by interacting with the bodys endocrine system. Since it resembles endogenous GHRH, it produces a similar effect, which is to bind to receptors that tell the pituitary gland to release more growth hormone into the bloodstream.

The result? Growth hormone (GH) levels increase.

What is growth hormone? An essential part of the bodys tissue construction process.

Growth hormone, also called human growth hormone (HGH), is involved in many biological functions including the reproduction of cells and the repair of tissue [2]. Because GH is so important for the growth and repair of tissue, there is currently strong research interest in the extent to which HGH may improve body composition and performance.

However, administering exogenous HGH directly to test subjects can produce a range of serious side effects, including swelling, joint pain, carpal tunnel syndrome, and an increased risk of diabetes [3]. It may also increase the risk of certain types of cancer, such as Hodgkins Lymphoma [4]. These risks mean that HGH research is strictly regulated and tightly controlled.

Thats the beauty of sermorelin research.

Rather than administering HGH directly, researchers can use sermorelin to increase HGH levels in test subjects by naturally stimulating the pituitary gland to release more endogenous HGH. Instead of spiking HGH to supraphysiological levels, sermorelin is believed to produce a gradual increase in HGH in a stable, predictable way.

In the next section, well take a look at the main benefits and uses of sermorelin.

So, what are the Sermorelin benefits? Well, there are quite a few.

In 1997, sermorelin received U.S. Food and Drug Administration (FDA) approval for the treatment of growth hormone deficiency (GHD) in child and adult patients. It was available under the trade name Geref and was also used as a diagnostic agent to check pituitary gland function.

However, the USFDA withdrew approval for Geref in 2008 and it was subsequently discontinued. While the manufacturer stressed that this was for reasons unrelated to safety or efficacy, the simple fact is that sermorelin no longer has any recognizer therapeutic use. In other words, it is a research chemical and is not approved for human use.

As sermorelin is able to increase GH levels in human test subjects, there is strong interest among peptide researchers as to whether it may offer the following benefits:

In summary, while sermorelin is a research chemical and no longer has FDA approval, ongoing research indicates that it may offer a wide range of benefits. Hopefully, researchers interested in exploring sermorelin can consult the relevant literature when calculating sermorelin dosage.

Well now explore the documented sermorelin side effects.

Sermorelin appears to offer several benefits, but are there any sermorelin side effects?

Firstly, researchers need to know that the decision to withdraw sermorelins FDA approval was for reasons other than safety or efficacy. There is no research to date that has linked sermorelin to any clinically significant adverse effects in test subjects.

In general, sermorelin is considered by most researchers to be well-tolerated by test subjects [12]. Side effects from sermorelin administration are rare and not severe. Some of these more mild side effects include:

More rarely, some test subjects have reported the following side effects:

To minimize the risk of test subjects experiencing side effects as a result of sermorelin administration, researchers are advised to consult the relevant literature when designing an experiment.

In the following section, well outline how this research chemical has been used in past studies.

Researchers interested in working with sermorelin may use this sermorelin dosage calculator during the design and planning phases of the research process. Below, the main doses used in past sermorelin studies are highlighted along with any general guidance that researchers may need to be aware of.

Sermorelin acetate usually comes in powder form. Prior to administration, researchers must first reconstitute it with bacteriostatic water by injecting water with a large mixing syringe against the glass wall of the vial. This water must be swirled, gently, around the vial until all of the powder is dissolved.

Researchers should follow the directions for how much water to add. For a 15 mg vial of sermorelin acetate, 7.5 ml of bacteriostatic water is typically required. Note that 10 units on an insulin syringe usually equates to 200 mcg of sermorelin.

Reconstituted sermorelin must be refrigerated and kept away from heat, light, moisture. It can be stored for up to 90 days. Researchers are advised to discard any sermorelin that is cloudy or contains particles.

When sermorelin held FDA approval as a treatment for GHD, it was administered intravenously as a subcutaneous injection. However, sermorelin may also be administered into the muscle as an intramuscular injection.

In terms of the timing of these injections, sermorelin has been administered to test subjects In past studies at night, at least two hours after eating. As HGH levels naturally peak at night, this protocol is believed to enhance HGH secretion.

During the period when sermorelin held FDA approval and was used to diagnose idiopathic GHD in children, it was administered intravenously at a dose of 1mcg per kilogram of body weight.

To date, sermorelin has not been approved for any other purpose and is currently classified as a research chemical. Therefore, based on the available data, researchers interested in experimenting with sermorelin for its purported recovery benefits may administer it in the following way:

While there is strong research interest in the application of sermorelin to improve the appearance of skin and reduce body fat, there is no published research to indicate the dosage at which it may be administered to this end.

Researchers interested in experimenting with sermorelin may consult the available literature regarding the past use of sermorelin as a treatment for GHD. This research indicates that a dose of 1mcg/kg of body weight provides a clinically significant effect in test subjects.

As with anti-aging and weight loss, there is currently very strong research interest in the application of sermorelin to lean muscle increase and athletic performance in test subjects. However, to date, no research has been published to indicate the dosage at which sermorelin may be administered for this purpose.

Based on the available data, doses of 1mcg/kg of bodyweight appear to produce a discernible effect. Researchers interested in exploring these purported benefits of sermorelin may consider this as a starting dose for any experiment they decide to conduct.

Researchers interested in experimenting with sermorelin should note that while this peptide has previously held USFDA approval as a treatment for GHD, it is currently classified as a research chemical and has no recognized therapeutic use.

Sermorelin | Reviews, Dosage & Clinical Trials – Peptides

Effective treatment of adult-onset growth hormone insufficiency: Sermorelin is an effective and attractive treatment of adult-onset GH insufficiency. Unlike rhGH, sermorelin does not stimulate IGF-1 production in the liver and instead stimulates the pituitary gland to produce and secrete endogenous hGH, giving it a number of clinical advantages over exogenous hGH.

Notably, according to a 2006 article by Richard Walker, overdoses of endogenous hGH are difficult if not impossible to achieve as the effects of sermorelin are regulated by negative feedback involving the inhibitory neurohormone, somatostatin.

Sermorelin is not associated with the pro-cancer and pro-diabetes side effects linked to long-term hGH therapy, and is thus heavily researched to treat adult-onset GH insufficiency along with being used in longevity medicine for preserving youthful anatomy and physiology [5].

Positive effects on body composition: Sermorelin has been identified as one of several growth hormone secretagogues (GHS) that can help manage body composition in hypogonadal males. In a 2020 paper, Deepankar et al. noted that sermorelin can significantly improve body composition (in hypogonadal males) while ameliorating specific hypogonadal symptoms such as fat gain and muscular atrophy [6].

While the authors suggest that sermorelin could be used to achieve lean mass gain in both hypogonadal males and men with subclinical hypogonadism, to date, there is no published research that has investigated sermorelins effect on body composition in healthy subjects, highlighting an area for further research.

Potential anti-aging benefits: A 1992 study identified sermorelins potential anti-aging benefits after nine young male test subjects (22 to 33 years old) and ten elderly male test subjects (60 to 78 years old) were administered the peptide. The study found that short-term subcutaneous sermorelin injections enabled healthy male test subjects to reverse age-related decreases in GH and levels of IGF-I [7].

A 1997 single-blind randomized placebo-controlled trial found that elderly male and female test subjects who received nightly subcutaneous injections of sermorelin for 16 weeks experienced a significant increase in skin thickness. The peptide was found to produce significant increases in lean body mass in male test subjects and notable increases in libido and wellbeing. Male test subjects gained an average of 1.26 kg of lean body mass by the end of the trial [8]

Sermorelin and heart health: Sermorelin has been investigated alongside other GHRH agonists as a potential treatment for myocardial infarction scarring in swine [9]. The 2015 study found that sermorelin offered a number of benefits in post-heart attack animal models, which included:

As a result, there is research interest in sermorelins heart health-related benefits, namely in its potential to treat problems resulting from cardiac remodeling and ability to heal damage in myocytes following a heart attack.

Sermorelin 101: What Is Sermorelin? | Sermorelin Side Benefits & Side …

Our bodys size, health, and overall composition are largely determined by its ability to produce growth hormones, which are generated from the anterior pituitary gland, a tiny gland at the base of the brain. One of these hormones is thehuman growth hormone(HGH), which facilitates growth in children and maintains organ and tissue health throughout ones life. However, as we get older (or, in the case of certain disorders, from childhood), our bodys ability to produce HGH diminishes, resulting in some of the changes we commonly associate with the aging process.

To that end, there has been a large interest in using synthetic HGH to stave off the aging process, which can ostensibly help maintain muscle and bone mass even into middle age and our later years. While HGH is often available for those suffering from specific childhood growth hormone deficiencies, it is becoming more common in adult therapies as well.

Despite this popularity, there are a number of concerns about the use of synthetic HGH in hormone replacement therapies; to that end, many patients consider hormone therapies involving sermorelin acetate as a safer, more ethical replacement.

Sermorelin acetate, or factor 1-29 NH2acetate, is a growth hormone releasing hormone (GHRH) naturally produced by the brain. Its goal is to encourage the pituitary gland to produce and secrete human growth hormone (HGH). Its not a growth hormone by itself, but instead a growth hormone secretagogue, a separate hormone that stimulates the production of HGH by binding specific receptors to increase HGH production and secretion.

When we are young, our bodies produce sermorelin acetate, allowing our pituitary gland to facilitate the production of HGH. HGH has theeffectof regulating body composition and fluids, as well as facilitating muscle and bone growth, increasing metabolism and improving heart function. In order to produce the levels of HGH required to grow and maintain healthy brain and organ tissue, the body must produce equivalent levels of sermorelin acetate to facilitate its production in the pituitary gland.

HGH is extremely important to human beings during childhood, as it facilitates the growth that occurs during the first twenty years of our lives. As with other hormones like testosterone, the human body typically produces the highest amounts of sermorelin acetate during puberty, leveling off in their twenties and beginning to slowly but steadily diminish once a person enters their thirties and forties. Older men tend to be more likely to suffer from lower levels of sermorelin acetate, as the aging process has slowed down the bodys production of the hormone.

As men age, they can be more likely to suffer fromadult-onset growth hormone deficiency(AGHD), a phenomenon characterized by a relative increase in fat mass, and a commensurate decrease in muscle mass. Sufferers also experience lower energy levels, anxiety and depression. Furthermore, AGHD sufferers also have maladjusted lipid levels, raising their levels of LDL-cholesterol and triglycerides.

Overall, as HGH levels begin to slow down as we get older, we begin to experience the effects commonly associated with aging. These include weight gain, lower muscle mass, lower bone density, insomnia, and changes in our own personality and self-regard. Many different metabolic changes begin to occur, which can lead to greater risk for heart disease, diabetes, metabolic syndrome. These relate closely to many of the common causes of death for people over fifty years of age.

Unlike other hormones like testosterone, sermorelin has an extremely short half-life approximately eleven to twelve minutes after administration, most sermorelin is rapidly cleared from circulation. Most adults have aclearance valueof 2.4 to 2.8 liters per minute (L/min).

There are a number of factors that can contribute to the onset of AGHD:

When the human body fails to produce sufficient levels of sermorelin, the pituitary gland is not motivated to produce HGH, leading to the following side effects:

While these physiological symptoms can have an effect on your physical health, having AGHD corresponds with real, practical deficits in your everyday life:

As we get older, our physical appearance begins to change in ways we often cant expect and do not want. However, by encouraging the stimulation of HGH, we can safely and effectively stave off those effects and increase our quality of life.

Growth hormone stimulationtherapy (GHST) is a regimen that involves administering supplements of sermorelin acetate into the body as a replacement for the bodys natural production of the hormone. This is particularly useful for people who experience lower than usual levels of sermorelin production, as well as those who would like the benefits of HGH without taking it directly.

Sermorelin therapy is simple, especially when thoroughly supervised by a wellness professional. Patients are given a prescription of a multi-dose, injectable vial, which contains a powder disk containing sermorelin acetate. The powder combines with bacteriostatic water to form the solution found in the injectable vial.

Mostsermorelin therapy regimensinvolve the patient self-administering a dose into the body fat, just under the skin with a small needle. Most regimens will involve injecting you with more frequent doses of sermorelin at the beginning of therapy (known as a loading period), then tapering off over time. Sermorelin encourages drowsiness since growth hormones are typically released by the body when were asleep; its recommended that patients take their doses right before bedtime.

When this sermorelin is administered into the body, it goes to the pituitary gland and binds to the appropriate receptors, encouraging the pituitary gland to produce greater amounts of HGH. Given this added stimulation, the pituitary produces more HGH than a body suffering from AGHD or otherwise diminished growth hormone production would normally make. This encourages the kind of health and physiological benefits that come with the HGH levels of a younger person.

While there are absolutely instances of people directly taking HGH to improve their overall strength and well-being, especially athletes and older people hoping to minimize the effects of the aging process. However, the use of this therapy isextremely controversial, as there have been noted reports of serious side effects in some patients. The Code of Federal Regulations, for instance, prohibits the use of HGH in adults, save for some special cases like those suffering fromdwarfism or AIDS.

Some concerns about the direct application of HGH therapy include the mitogenic nature of the hormone, which may awaken latent cancers or lead to diabetes and other disorders. Other potential side effects include early development of carpal tunnel syndrome, increased resistance to insulin, edema (swelling of the arms and legs), muscle and joint pain, and gynecomastia in men. While research is still pending on the long-term effects of HGH therapy, it is generally considered to be fairly risky and not worth pursuing.

However, with sermorelin therapy, the only HGH being produced is that generated naturally by the bodys pituitary gland. All the treatment does is increase the levels of GHRH in the body, thus signaling to the body to synthesize HGH on its own. This side-steps many of the potential side effects and long-term potential problems of HGH therapy, while achieving similar results. By motivating the body to produce HGH on its own, sermorelin therapy is generally considered safer and more ethical.

Semorelin therapy is perfectly safe and healthy, particularly when a regimen is supervised by wellness professionals, in conjunction with recommended lifestyle changes such as diet and exercise.

Synthetic sermorelin has existed for quite some time on the commercial market as an alternative to the synthetic rhGH, meant to treat stunted growth in children; however, it is much better suited to use in adult anti-aging therapies (and far safer than HGH) for thefollowing reasons:

In short,sermorelin therapyis a much safer and preferable alternative to HGH therapy, particularly for older patients. Rather than risking the potential side effects of HGH, including overdose and building up a resistance to the hormone, GHST simply encourages the body to increase more of what it naturally produces.

If sermorelin therapy is something you would like to get involved with, the best plan is to seek outwellness professionalsthat specialize in anti-aging hormone therapies, particularly sermorelin treatments. With their help and supervision, you can begin an effective regiment of sermorelin therapy, in conjunction with properdiet, exercise, and other lifestyle changes.

In total, there are 20 different amino acids. They all have vastly different properties and exert different effects within the system.

Whilst a protein may contain 50 or more amino acids, the balance of the amino acids it contains ultimately determines what kind of impact it will have on the body.

The same goes for peptides too; amino acids can lead to everything from CNS (Central Nervous System) responses to the replenishment and evolution of organ tissue and muscle cells.

We can only synthesise 11 of these 20 amino acids on our own using our internal mechanisms; we need to source the other 9 (known as essential amino acids because they are essential components of our nutritional intake) from food meaning that the spectrum of benefits on offer by the proteins and peptides we naturally produce are somewhat resigned to the effects on offer with these 11 acid types only.

Bioengineering allows us to combine these 11 man made amino acids with any number of the other 9 essential amino acids to produce compounds that are capable of exerting varying effects on the body.

Not only that, but we can actually choose to alter the structure of either essential or nonessential amino acids, further manipulating the effects they can exert.

Regardless of the manner in which a peptide or protein is created (either naturally occurring or unnaturally synthesises in a laboratory) the crux of the entire operational efforts of these molecules is indeed the amino acid code contained within.

As previously stated, these individual acids can lead to any one of several responses within the body combining them together can exert either multiple or one primary effect.

Its still not entirely known how certain amino acid sequences can lead to certain effects occurring.

Being that amino acids are considered to be the building blocks of the human body, it is perhaps possible that each and every hormone / enzyme contains its own unique amino acid code, and once discovered, the effects of said hormone or enzyme can be recreated / replicated.

That certainly appears to be the case in this instance, because the 29 amino acid code contained within sermorelin directly mimics the effects of growth hormone releasing hormone.

Sermorelin Therapy Benefits, Uses, Side Effects, Risks, More

To properly grow and develop, your body needs human growth hormone (hGH). This is a peptide hormone produced in the tiny part of your brain called the pituitary gland. Although hGH plays its most crucial role during childhood and adolescence, it continues to maintain healthy tissues and organs throughout your life. Because of that, hGH levels that are lower or higher than typical can lead to health problems both in children and adults.

As often is the case with such complicated machines as our bodies, hGH does not act alone. A molecule called the growth hormone-releasing hormone (GHRH) controls hGH by releasing it from the pituitary gland into the bloodstream. If your blood test indicates low levels of hGH, your doctor may recommend injections of a synthetic form of GHRH, called sermorelin.

Keep reading to learn more about sermorelin, its benefits and risks, and when to consider using or avoiding sermorelin injections.

Sermorelin is used to diagnose and treat poor growth in children. Its also sometimes used off-label to treat hGH deficiency in adults. Some research has suggested that it can be beneficial in people with certain recurrent brain tumors.

Children usually benefit the most from sermorelin. One older study reported that a daily injection of sermorelin increased growth rate in 74 percent of children after just 6 months.

Studies investigating benefits of sermorelin in adults are scarce, but researchers have observed that sermorelin injection increases hGH levels in the bloodstream. These findings have led to widespread claims that sermorelin is an anti-aging therapy that can restore your bodys natural hGH production. Indeed, some older research suggests that sermorelin may increase:

However, definitive research to support the anti-aging effect of sermorelin is lacking. The use of sermorelin in healthy adults to reverse the effects of aging and in bodybuilding remains controversial.

Although long-term risks of sermorelin use are not known, its usually well-tolerated. However, as with any synthetic drug, its possible to have an allergic reaction. Let your doctor know about any allergies before taking this medication.

If you notice any of the following symptoms of a severe allergic reaction, call emergency medical services or go to the nearest emergency room:

The most common side effect of sermorelin is caused by its injection under your skin. You may experience any of the following at the site of injection:

These reactions are typically short-lived and disappear without any action. As you get better at self-administering the shots, these symptoms may stop for good.

Other, much less common side effects of sermorelin may include:

Sermorelin may interact with other medications. Drug interactions that may interfere with sermorelin include:

Make sure to let your doctor know about any medications and supplements you take (including vitamins) before starting sermorelin treatment.

Children and youths with poor growth are the primary candidates for sermorelin injections. In this group, sermorelin can help with both diagnosis and treatment of hGH deficiency.

Adults with diagnosed hGH deficiency can also benefit from sermorelin, according to older research. Healthy adults sometimes use this therapy for anti-aging and for bodybuilding; however this use remains controversial due to the scarcity of scientific evidence.

People with certain medical conditions may require additional screening before taking sermorelin and sometimes should avoid this therapy. These conditions include:

You dont need to visit a doctors office for sermorelin injections. Instead, you can self-administer injections at home. Sermorelin is injected subcutaneously, which means under the skin.

To prevent contamination, wipe the rubber vial stopper with an antiseptic before puncturing it with the needle. When injecting, target the fatty tissue just below the skin. Many people inject their stomach or thigh. To avoid bruising and soreness, its best to switch up the location of the injection site. Ask your doctor to show you the best injection technique.

Sermorelin is administered once a day, ideally at night. Your doctor will determine your dosage and length of treatment based on your individual factors.

You may be wondering: If the purpose of sermorelin therapy is to increase the levels of hGH hormone, why cant you just inject hGH? The answer is that many people do. In fact, research suggests that genetically engineered hGH is an effective treatment for both poor growth in children and hGH deficiency in adults. Unfortunately, hGH therapy is associated with numerous risks and side effects. Therefore, it may not be appropriate for some people.

Sermorelin helps your body produce more hGH. Children with growth delays and adults with hGH deficiency may benefit from this therapy. Although some healthy adults take it to prevent aging and for bodybuilding, there is no definitive research suggesting that sermorelin is effective for either of these purposes.

Although this medication is usually well-tolerated, tell your doctor about any allergies and medical conditions you have as well as medications and supplements you take. Check in regularly with your doctor while youre taking it.

Sermorelin vs Ipamorelin: Best Guide in 2022 – PeptideSciences.com

Sermorelin vs Ipamorelin

Sermorelin and ipamorelin peptides are very similar in many ways. Despite their similarities, however, these two peptides are different enough that their applications can be tailored for specific needs. Both peptides stimulate the natural secretion of growth hormone, but they do so via different receptors. As a result of their effects on growth hormone (GH) levels, Ipamorelin and Sermorelin both cause increased fat burning and muscle building, enhanced long bone growth, decreased inflammation, and improved wound healing. However, their actions via different receptors result in these two peptides having slightly different ancillary effects.

Sermorelin vs Ipamorelin: Receptor Science

Sermorelin is an analogue of growth hormone-releasing hormone (GHRH) and binds to the GHRH receptor (GHRH-R). Ipamorelin, however, is a ghrelin analogue and binds primarily to the growth hormone secretagogue receptor (GHS-R). While both peptides can be referred to under the umbrella category of growth hormone releasing peptides, their different receptor binding preferences mean they have different effects on GH levels.

At baseline, Sermorelin potentiates GH release and helps to extend GH highs. It is best thought of as extending GH peaks and prolonging the amount of time that GH levels are elevated while preserving the normal ebb and flow (pulsatile secretion) of GH throughout that day. Ipamorelin, on the other hand, is better thought of as dramatically raising GH levels, sometimes by as much as 13 times above baseline levels. Ipamorelin has dramatic, but short-lived effects on GH levels.

Sermorelin and Growth Hormone Potentiation

The GHRH-R is the primary receptor on the anterior pituitary gland for controlling growth hormone release. When stimulated, it causes the release of growth hormone. Research shows that Sermorelin binding to the GHRH-R is effective at concentrations as low as 0.4x10-15M[1]. This makes Sermorelin an extremely potent GHRH agonist and approximately 50 times more potent than naturally occurring GHRH. This is the reason that it was originally referred to as a super-active analogue of growth hormone releasing hormone[2].

Interestingly, Sermorelin tends to not cause massive increases in GH levels when it is administered. It does, however, augment the duration of GH release. That is to say, while Sermorelin definitely increases GH levels, its primary effect is to extend the duration of GH release, helping to maintain peak levels for longer periods of time[3]. By extending the release of GH, Sermorelin does, in fact, raise GH levels but it also smooths out the peaks of GH release and widens them a bit. This does not, however, obliterate the normal pulsatile secretion of GH, which is important for minimizing side effects. In fact, Sermorelins biggest benefit is the fact that it preservers the normal physiologic pattern of GH release, thus mitigating side effects like swelling, joint pain, and excessive long bone growth[4].

Ipamorelin and Growth Hormone Peaks

Ipamorelin (as well as ghrelin) is an amplifier of GH pulsatility and is speculated to play a role in creating a set point for insulin-like growth factor 1 levels[5]. Research has shown that subcutaneous administration of Ipamorelin causes an intense spike in growth hormone levels just 5-15 minutes after injection followed by a relatively rapid decline. Thus, ipamorelin does not really potentiate GH secretion like Sermorelin does. Instead, ipamorelin is better thought of as boosting maximum levels of growth hormone output for a very short duration of time. Depending on when and how ipamorelin is administered, this could mean augmenting peak GH levels or raising trough levels. Thus, timing of ipamorelin administration can, to some extent, affect the peptides effects.

Ipamorelin, at its ED50 (50% of the maximum effective dose), causes plasma GH levels to increase to approximately 65 ng/mL in animal models. Normally, growth hormone levels in men are below 5 ng/mL while in women they are below 10 ng/mL. This means Ipamorelin administration raises GH levels by anywhere from 6.5 to 13 times the maximum level. In children, growth hormone levels range from 0-20 ng/mL based on age. Ipamorelin has a short half-life of two hours. When administered, it causes maximum GH release after about 40 minutes followed by an exponential decline[6].

This rapid on, rapid off property of Ipamorelin is a holdover from its natural counterpart, ghrelin. Recall that ghrelin and Ipamorelin can both stimulate appetite. This occurs via binding to the GHS-R and subsequent release of neuropeptide Y. Given that it takes time to eat and digest food, it makes sense that ipamorelin would have its maximum effects approximately 40 minutes after injection (or release in the case of ghrelin). This gives the peptide its best chance of making using of nutrients for building muscle, bone, connections between neurons, and more.

Sermorelin vs Ipamorelin: Structure and Route of Administration

Sermorelin is made up of the first 29 amino acids from the much larger, naturally occurring GHRH peptide. It is the smallest fraction of GHRH than retains all of the properties of the parent molecule. Weighing in at 3357.9 g/mol, Sermorelin is a relatively large, heavy peptide that must be injected sub-cutaneous to be absorbed. It is not orally bioavailable. As a result of its large size, Sermorelin has a more significant three-dimensional structure than Ipamorelin and is thus is a little less stable in terms of storage half-life.

Ipamorelin is substantially smaller than Sermorelin at just5 amino acids and 711.868 g/mol. It is a derivative of GHRP-1, which is itselfa derivative of met-enkephalin. Though the most common route of administrationfor Ipamorelin is via sub-cutaneous injection, the peptide is also orallyactive and can even be absorbed though the nasal mucosa.

Ipamorelin vs Sermorelin: Lean Body Mass

Both Sermorelin and Ipamorelin favor the development of lean body mass over fat mass, but Sermorelin is the more potent of the two. This arises from the fact that Sermorelin is both a growth stimulator and a fat burner while Ipamorelin is a more general growth stimulator. That is not to say that Ipamorelin isnt effective, it is, but ipamorelin isnt as strictly favorable of lean body mass deposition as Sermorelin. This difference arises from the fact that Ipamorelin is a ghrelin analogue and ghrelin favors food intake in general. Its growth hormone boosting properties shift the overall balance away from fat deposition and toward lean body mass deposition, but the Ipamorelin peptide is best thought of as a general weight boosting peptide while Sermorelin is best thought of as a more exclusive booster of lean body mass. In fact, Sermorelin is often referred to as a lipolytic or fat-burning peptide.

Both peptides stimulate the development of bone and other connective tissue, but Ipamorelin appears to have the advantage in this realm. In fact, ipamorelin is so effective in boosting bone density and mineralization that it has been investigated as a potential treatment for corticosteroid-induced bone loss as well as osteoporosis[7], [8].

When it comes to muscle growth, Sermorelin is probably the big winner, though this can be debated endlessly. Sermorelin not only boosts muscle hypertrophy and hyperplasia, it reduces fat mass and thus causes a shift in body chemistry toward lean body weight. In other words, Sermorelin will always favor the production of lean body mass even if diet is not perfectly geared toward muscle development. Ipamorelin, on the other hand, is more of a mixed bag. It will always cause muscle growth, but ipamorelin may channel some of those calories into fat deposition as well.

Ipamorelin vs Sermorelin: Anti-Aging Properties

Both Ipamorelin and Sermorelin, via their GH releasing potential, have potent anti-aging properties. Sermorelin, however, is the clear front runner in this particular face off. Sermorelin has been shown to improve joint function, skin thickness, skin collagen structure, wound healing, cardiac fibrosis, strength, and metabolism. According to Dr. Richard Walker, Ph.D., of the International Society for Advanced Research in Aging, Sermorelin helps to preserve more of the growth hormone axis than most other GHRH analogues, resulting in a more youthful hormone profile. In other words, if you took profiles of GH biochemistry throughout an individuals lifetime, you would find that Sermorelin tends to dial back that chemistry to a more youthful setting.

Ipamorelin as Pain Reliever

One of the biggest differences between Ipamorelin and Sermorelin lies in the fact that Ipamorelin triggers the release of neuropeptide Y. This peptide is an important neurotransmitter in the control of appetite and food preference, but it also plays an important role in how we perceive pain. In fact, the connection between food and good feelings is likely due, in part, to the effects of neuropeptide Y.

Research in rats indicates that Ipamorelin may help to reduce pain perception by has much as 2-fold. This is particularly true of visceral pain, which is to say stomach pain. Visceral pain is difficult to treat, so ipamorelin offers a potential starting point for understanding how to better control the pain associated with conditions like irritable bowel syndrome, Crohns disease, ulcerative colitis, and more. There are also potential applications in neuropathic pain syndromes like diabetic neuropathy and degenerative disk disease[9].

Sermorelin and Sleep

Research in rats shows that Sermorelin is an effective regulator of the sleep cycle. Sleep and aging go hand int hand, with one affecting the other such that older people often have less adequate less restful sleep. Sermorelin appears to achieve its sleep benefits by regulating orexin release from specialized neurons in the brain. Orexin is an important neurotransmitter in sleep regulation and Sermorelin appears to boost orexin secretion. This leads to an increase in non-REM slow-wave sleep, which is associated with more restful sleep, improved immune function, better wound healing, and happier mood[10], [11]. Its effects on sleep may be one of the reasons that Sermorelin is a potent anti-aging peptide.

Sermorelin vs Ipamorelin: Summary

Sermorelin peptides and Ipamorelin peptides are more similar than they are different, but that doesnt mean there arent distinctions between these two growth-promoting peptides. Practically speaking, Sermorelin is the all-around peptide. It promotes lean body mass gains, boosts fat burning, and fights the effects of aging. It is also a more holistic simulator of the GH axis and, as such, helps the body to maintain youth-like patterns of GH secretion.

Ipamorelin is the more potent of the two peptides. Its effects are large, but relatively short-lived. Ipamorelin is a gainer peptide. It builds lean body mass, but also builds overall body mass. It is a potent stimulator of bone growth and has some pain fighting properties as well.

There has been some research investigating the effects of combining Sermorelin and Ipamorelin. Because these peptides affect two different receptors, their actions when combined tend to be synergistic. Unfortunately, the research in this area is limited, so there isnt a great deal of data on how the combination of these two peptides can help to improve appetite, alter body composition, fight off cardiovascular disease, slow the progression of aging, and promote general good health. In the end, both Ipamorelin and Sermorelin have been studied extensively, but individually, for their significant impacts on GH. Both peptides are effective, but have slightly different ancillary effects that have driven researchers in different directions as they explore potential applications for ipamorelin peptides and sermorelin peptides.
