Curious about sermorelin benefits? Then you’re in the right place.

Published studies indicate that this research peptide can offer significant benefits when properly administered.

It has the documented ability to stimulate the pituitary gland to release growth hormone (GH) and has a proven track record of helping to diagnose and treat growth hormone deficiency in children.

Below, we aim to provide a summary of the research-backed benefits of sermorelin and illuminate potential avenues for further research.

At the end of this guide, we’ll also share our recommended vendor for researchers looking to buy this fascinating research peptide.

What is Sermorelin?

Sermorelin acetate is a polypeptide that’s also known as GHRH (1-29). It’s designated as such because it contains the first 29 amino acids of endogenous human growth releasing hormone (GHRH) [1]. In other words, it’s an analogue (or “version”) of GHRH, rather than actual GHRH.

What makes sermorelin unique is that despite containing just 29 out of the 44 amino acids found in endogenous GHRH, it’s a fully functioning fragment. This makes it the shortest known GHRH analogue to have the full biological function of human GHRH.

When administered subcutaneously, sermorelin mimics endogenous GHRH and binds to the GHRH receptor to stimulate the pituitary gland to produce and release more growth hormone (GH) [1].

In 1997, the U.S. Food and Drug Administration (FDA) approved sermorelin for the purpose of diagnosing and treating idiopathic growth hormone deficiency (GHD) in children [2]. It was released under the trade name Geref, and continued to be sold until 2008. In that year, the drug’s FDA approval was withdrawn for reasons other than safety and efficacy [3]. Currently, the drug is still available as a reference material to qualified researchers.

Benefits of Sermorelin

Sermorelin offers numerous documented benefits as follows:

Diagnostic test for GHD in children

When it held FDA approval (1997-2008), sermorelin’s primary use was to diagnose idiopathic growth hormone deficiency (GHD) in children. A review of sermorelin’s use for this purpose noted that sermorelin could, when administered intravenously at a dose of 1μg/kg body weight, produce a “rapid hormone response.” It’s considered to be more efficient at diagnosing GHD than other provocative tests [1].

Treatment for GHD in children

Clinical data showed that once-daily subcutaneous injections of sermorelin dosed at 30 mcg/kg body weight were “effective in promoting growth” in prepubertal children diagnosed with idiopathic GHD [1]. However, the height velocity achieved with sermorelin treatment was less than that achieved by regular HGH (i.e., somatropin) at the same dosage.

Safer than somatropin for GHD treatment

Although the effects of the recommended dosage of sermorelin (30 mcg/kg body weight) have not been directly compared with those of somatropin, the limited available data shows that an “intravenous single dose and repeated once-daily subcutaneous doses of sermorelin are well tolerated” [1]. This indicates that sermorelin has a better safety profile than somatropin for treating children with idiopathic growth hormone deficiency, and suggests that doctors were more likely to prescribe sermorelin as an HGH alternative due to its favorable safety profile.

Increased HGH production and secretion

One of sermorelin’s proven benefits is to increase the production and release of HGH in the body. In a study on rainbow trout, sermorelin acetate was shown to be effective at stimulating the pituitary gland to naturally produce and deliver more HGH into the system [5].

Potential treatment for male hypogonadism

In 2020, a review of existing literature on the use of growth hormone secretagogues (GHSs) suggested that sermorelin could be “a potential novel adjunctive therapy for some of the symptoms of hypogonadism” [4]. The review studied a number of GHSs including sermorelin and explored the “potential complementary role” they could play in the “management of hypogonadal and eugonadal males with metabolic syndrome or subclinical hypogonadism (SH).”

The authors of the review cautioned that current data on the clinical efficacy of GHSs (including sermorelin) remains lacking and concluded that their findings opened “opportunities for future investigation” [4].

Purported anti-aging benefits

Despite a distinct lack of supporting clinical data, anecdotal evidence suggests that some doctors at anti-aging clinics prescribe or advocate the use of sermorelin for its purported anti-aging benefits. To date, there have been no human clinical trials into sermorelin’s use for this purpose and experts recommend against using HGH or any related peptides to treat aging or age-related conditions.

Identifying the origin of the theory that sermorelin offers anti-aging benefits is beyond the scope of this guide, but the genesis may be a 2015 study conducted on swine with subacute ischemic cardiomyopathy. While the study didn’t involve sermorelin, it showed that growth hormone-releasing hormone agonists (GHRH‐As), similar to sermorelin, were able to reduce “myocardial infarct scarring” [6]. This study may have given rise to the theory that sermorelin, as a GHRH analogue, may offer comparable benefits in humans.

Purported performance-enhancing benefits

Anecdotal evidence suggests that many recreational and professional athletes, bodybuilders, and other individuals take, or have taken, sermorelin for its purported performance-enhancing benefits. To date, there have been no human clinical trials into sermorelin’s use as a performance-enhancing substance. However, the World Anti-Doping Agency (WADA) has banned the use of all growth hormone-releasing hormones (GHRHs) and related peptides including sermorelin from sports [7]. This strongly suggests that sermorelin can enhance athletic performance.

A randomized trial conducted in 2010 and funded primarily by WADA found that recreationally trained athletes who received growth hormone (2 mg/day) for 8 weeks experienced [8]:

  • Significantly reduced fat mass
  • Increased lean body mass through an increase in extracellular water
  • Increased sprint capacity

While this trial did not involve sermorelin, its findings do suggest that GHRHs like sermorelin may indirectly offer comparable benefits by stimulating the production and release of endogenous HGH. However, it should be noted that the increase in sprint capacity by the group that received HGH was “not maintained 6 weeks after discontinuation of the drug” and that the “study was too small to draw conclusions about safety” [8].

It should also be noted that under no circumstances do we encourage the self-administration of research peptides like sermorelin for recreational purposes.

Sermorelin and sleep

Sleep cycles play an important role in your body repairing tissue; many of our body’s repair functions happen when we are asleep. This also happens to be when your body naturally secretes the most HGH [9].

Research suggests that both tissue growth and healing are strongly associated with the higher HGH levels that are found in your body as you’re sleeping. For that reason, some people suggest that sermorelin, as a peptide analogue of GHRH, may help regulate sleep indirectly, by way of increasing the production and release of endogenous HGH.

While sermorelin has yet to be tested for this purpose, anecdotal evidence from doctors who work at anti-aging clinics suggests that sermorelin can help improve the quality of patients’ sleep.
