What Is Sermorelin?
Derived from an endogenous hormone called GHRH, Sermorelin is a synthetic peptide that effectively binds to somatotroph cells in the pituitary gland, triggering the release of growth hormone.
Initially, Sermorelin received approval from the United States Food and Drug Administration (FDA) for the treatment of short stature disorder in children. It proved to be safe and effective in promoting catch-up growth by increasing GH and insulin-like growth factor 1 (IGF-1) levels.
Two different longer-term studies evaluating once-daily subcutaneous injection of sermorelin demonstrated that Sermorelin can safely boost GH and IGF-1 levels in healthy older adults, leading to fat loss and increased lean body mass after sermorelin treatment:
• Roughly 2x secretion of GH
• Increased IGF-1 levels
• Increased lean body mass and reduced fat
Moreover, human trials demonstrated that Sermorelin can safely boost GH and IGF-1 levels in healthy older adults, leading to fat loss and increased lean body mass.
The use of Sermorelin and other GH-releasing peptides in anti-aging research has gained significant interest due to their potential to enhance body composition, improve skin thickness, well-being, and libido. However, it’s important to note that further research is still needed in this area.
What Does Sermorelin Do?
Sermorelin, also known as GHRH (1-29), is a 29 amino acid peptide derived from the first 29 amino acids of the endogenous peptide hormone GHRH. It falls under the category of growth hormone secretagogues (GHSs) due to its ability to enhance the natural production of growth hormone.
There are two subcategories of GHSs: compounds that bind to the growth hormone secretagogue receptor (GHS-R) and compounds that bind to the growth hormone-releasing hormone receptor (GHRHR). Sermorelin belongs to the latter category, as it is a 29-amino acid fragment derived from GHRH.
Sermorelin was initially FDA-approved in 1990 for diagnosing GH deficiency in children. It rapidly stimulates GH secretion, making it a valuable diagnostic tool for identifying the cause of growth deficiencies. Subsequent studies led to another FDA approval in 1997, specifically for the treatment of growth failure in children with idiopathic GH deficiency. However, due to manufacturing issues and competition from recombinant human growth hormone (rhGH), Sermorelin was withdrawn from the market in 2008.
Unlike rhGH, which delivers a single bolus of hormone, Sermorelin stimulates pulsatile GH secretion that mimics the natural pattern of GH release. This pulsatile secretion is believed to be essential for maximizing the benefits of the GH-IGF-1 axis. Furthermore, Sermorelin helps maintain GH and IGF-1 levels within a physiologically safe range, avoiding the negative consequences associated with GH therapy.
The Benefits of Sermorelin Peptide Therapy
Sermorelin, through its ability to stimulate GH and IGF-1 secretion, offers a range of benefits for researchers and potential therapeutic applications. Let’s explore some of the notable benefits:
1. Diagnosis of Growth Hormone Deficiency
Sermorelin has been extensively studied for its effectiveness in diagnosing growth hormone deficiency (GHD). Its potent ability to induce GH secretion in individuals with intact hypothalamic-pituitary axis (HPA) makes it a valuable tool for identifying the cause of growth hormone deficiencies.
2. Treatment of Short Stature in Children
Following FDA approval in 1997, Sermorelin has been used to treat children with short stature caused by idiopathic GH deficiency. Studies have shown that Sermorelin effectively induces catch-up growth in a significant percentage of growth hormone-deficient children.
3. Increased Growth Hormone Secretion in Healthy Adults
Research has demonstrated that Sermorelin can increase growth hormone secretion, even in healthy older adults with lower endogenous levels of GH. Both intravenous and subcutaneous administration of Sermorelin have shown positive results in boosting GH and IGF-1 levels.
4. Improvements in Body Composition and Fat Loss
Sermorelin has been associated with increased lipolysis (fat breakdown) and reduced fat mass. By stimulating GH secretion, it promotes the utilization of stored fat for energy, leading to improved body composition.
5. Enhanced Muscle Strength and Exercise Performance
Through the upregulation of IGF-1 secretion, Sermorelin has the potential to improve muscle strength and enhance exercise performance. IGF-1 plays a crucial role in mediating the effects of GH on muscle growth and repair.
6. Increased Skin Thickness
One of the desirable effects of GH is its ability to thicken the skin, which can help reduce the appearance of wrinkles and fine lines. Sermorelin, by stimulating GH secretion, may contribute to improved skin thickness and overall skin health.
7. Improved Memory and Well-being
Studies have shown that Sermorelin treatment can lead to improvements in cognitive function and memory. This effect is believed to be mediated by the upregulation of IGF-1, which plays a role in neuronal health and synaptic plasticity.
8. Increased Resting Energy Expenditure
Sermorelin has been observed to increase resting energy expenditure, which refers to the number of calories burned at rest. This effect can potentially contribute to weight management and metabolic health.
It is important to note that while Sermorelin has shown promising results in these areas, further research is needed to fully understand its therapeutic potential.
Safety and Side Effects of Sermorelin Peptide Therapy
Sermorelin has been extensively studied in clinical trials and has demonstrated an exceptional safety profile. The most commonly reported side effects are minor injection site reactions, such as pain and irritation. These reactions are typically mild and transient.
One of the reasons behind Sermorelin’s safety profile is its ability to leverage the natural regulatory mechanisms that control GH and IGF-1 levels. By mimicking the action of endogenous GHRH, Sermorelin ensures that GH secretion remains within a physiological range, avoiding the negative consequences associated with GH therapy.
It is recommended that researchers monitor IGF-1 levels while administering Sermorelin, as IGF-1 serves as a more stable indicator of GH secretion. Additionally, individuals with diabetes or pre-diabetes may consider monitoring glucose and insulin sensitivity during treatment.
While Sermorelin is generally safe, it is essential to consult with a medical professional before considering any peptide therapy or treatment.
Is Sermorelin Legal?
Sermorelin, though previously FDA-approved, is no longer available as a medical product due to commercial reasons. It is important to note that Sermorelin’s classification prohibits its marketing for human consumption and medical treatment in the United States, United Kingdom, and the European Union.
The lack of regulatory oversight in the peptide market has led to the emergence of unauthorized vendors making unsupported medical claims. These vendors face legal penalties in several countries, and consumers are exposed to health risks when using adulterated compounds.
Researchers should be aware of the regulatory landscape surrounding Sermorelin and prioritize purchasing from reputable vendors like Peptide Sciences, who adhere to rigorous quality control standards.
Current Peptide Regulations
Peptide therapies, including Sermorelin, operate within a nascent regulatory framework. The lack of clear regulations presents challenges for the approval and distribution of peptide products for clinical trials and medical use.
Despite the regulatory ambiguity, there is a growing demand for peptide products globally. It is crucial for qualified researchers to prioritize vendor quality and exercise caution when purchasing peptides. Established vendors with a track record of delivering high-quality research-grade peptides should be preferred.
Doping Drugs: Sermorelin and Competitive Athletics
Researchers interested in applying Sermorelin therapy to competitive sports should be aware that it is classified as a banned substance by multiple doping agencies. It falls under the category of non-specified substances and is prohibited for use by the World Anti-Doping Agency (WADA) and the United States Anti-Doping Agency (USADA).
Compliance with anti-doping regulations is essential for athletes and individuals participating in competitive sports.
Sermorelin Dosage and Administration
Sermorelin dosing can vary based on individual needs and treatment goals. It is crucial to establish an appropriate dosage that balances effectiveness and safety. Below is a hypothetical dosing protocol that researchers can consider:
- Tolerance Assessment: Begin with a subcutaneous injection of 100mcg of Sermorelin to assess individual tolerance.
- Low-Dose Protocol (200mcg/day): Administer 100mcg of Sermorelin via subcutaneous injection in the morning and again in the evening before bedtime, totaling 200mcg per day.
- High-Dose Protocol (600mcg/day): For individuals who do not respond to the low-dose protocol, administer 200mcg of Sermorelin in the morning, afternoon, and prior to bedtime, totaling 600mcg per day.
It is essential to monitor the effects of Sermorelin treatment by regularly measuring IGF-1 levels. Baseline blood work should be conducted before initiating treatment, followed by follow-up blood work after a minimum of two weeks at a specific dosing protocol.
Sermorelin is typically supplied as a lyophilized powder in a vial. Prior to injection, the powder must be reconstituted and dissolved in bacteriostatic water. Researchers should follow proper reconstitution procedures and handle the peptide with caution.
