What is it
Sermorelin is a synthetic peptide corresponding to the first 29 amino acids of growth-hormone-releasing hormone (GHRH), which stimulates the pituitary to produce and release growth hormone. It was historically FDA-approved (as Geref) for diagnostic testing and pediatric growth-hormone-deficiency evaluation, but that product was withdrawn from the U.S. market and it is no longer an approved drug; it is sometimes prepared by compounding pharmacies off-label. As a marketed 'research' or compounded peptide it lacks current FDA approval and standardized regulation, and robust long-term safety/efficacy data for anti-aging or performance use do not exist. It is not a dietary supplement and is often sold 'for research use only.'
Is it worth it for you?
Probably skip if…
- You expect a currently approved product — the original FDA-approved drug was withdrawn
- You would buy from 'research use only' vendors with no purity, sterility, or dosing oversight
- You are not prepared for limited long-term safety data for anti-aging or performance use
- You are uncomfortable with self-injection risks such as infection and contamination
- You compete in sport — GHRH analogs are prohibited under WADA rules
Safety
Common side effects
Reported historically: injection-site redness/pain/swelling, flushing, headache, occasional nausea or dizziness
Serious risks
- Unregulated purity, sterility, and dosing when obtained from research vendors
- Unknown long-term effects of sustained GH/IGF-1 elevation outside its original diagnostic indication
- Injection-related infection and contamination risk
- Rare hypersensitivity reactions; no clinical monitoring when self-administered
Who should avoid it
- Anyone without direct medical supervision
- Pregnancy and breastfeeding
- People with cancer or a history of cancer
- People with diabetes or impaired glucose tolerance (without supervision)
- Competitive athletes subject to anti-doping rules
Pregnancy & breastfeeding
Avoid — no safety data for this use.
Choosing a product
Be skeptical of
- 'Proven' anti-aging or performance benefits in healthy adults
- Vendors selling 'for research use only' product for human injection
- Implying current FDA approval or equivalence to prescription growth hormone
