Sermorelin
Reviewed
Short answer
Studies in people show a growth-hormone response. They do not prove broad anti-aging or muscle-building benefits. Former Geref products are no longer sold. This review found no current FDA-approved sermorelin product in the United States. Former Geref products were FDA-approved and are no longer sold. FDA said safety or effectiveness was not the reason for their withdrawal.

Study and product details
What it is
Sermorelin is a 29-amino-acid piece of growth hormone-releasing hormone (GHRH). GHRH is a body signal that helps the body release growth hormone. Geref products containing sermorelin were once FDA-approved and later discontinued. In 2013, FDA said the products were not withdrawn for safety or effectiveness.
Type of peptide: Growth hormone-releasing hormone analogue. This describes what the substance is or how it works. It does not show that it is safe, effective, or approved.
What has been studied?
- Limited: Research is too small or incomplete, or does not directly answer this question.
- Moderate: Useful evidence exists, but important limits remain.
Older studies in children exist. Research does not show that current products slow aging, reduce body fat, or build muscle.
Studies in people show that sermorelin can trigger growth-hormone release. A body response alone does not prove a health benefit.
Past records do not fully show whether modern compounded products are safe. They also do not show the safety of long-term use for wellness.
FDA records clearly describe the former Geref products. The identity and quality of each current compounded product must be checked separately.
Products with the same ingredient can differ.
The ingredient name does not tell you everything about a product. Check its other ingredients, its form, how it enters the body, and the use and people covered by the research or approval.
None identified in the United States.

What studies found
Studies in people show that sermorelin can trigger growth-hormone release. Older studies in children found limited growth results. A hormone response is not the same as a health benefit. These studies do not prove benefits for current compounded products.
Reliable studies do not show that current compounded sermorelin products slow aging or build muscle. They also do not show less body fat, better sleep, or that people live longer.
Which products do these findings apply to?
A former Geref approval does not make a current product FDA-approved. Current compounded sermorelin products are not automatically the same as the former Geref products.
Fact checks
3 statements checked. Read what the results mean.
“Sermorelin was once FDA-approved.”
FDA records document the former Geref approvals. FDA later found that safety or effectiveness was not the reason for withdrawal.

“Sermorelin raises growth hormone, so it is proven to slow aging.”
A hormone response cannot show that people live longer or age more slowly.
- What this answer is based on
- Studies of body changes in people
- Limits of this answer
- Hormone-response evidence cannot establish longer life or slower biological aging.

“Compounded sermorelin is an FDA-approved Geref generic.”
A former Geref approval does not make current compounded products FDA-approved. Current compounded products are not automatically the same as the former Geref products.

- Official record or product label
- Limits of this answer
- Current products marketed after Geref withdrawal.

Risks and safety limits
Approval of a former product does not prove the quality of a current product. This guide gives no dose, injection, or compounding instructions.
The 2026 WADA list names sermorelin as a prohibited growth hormone-releasing hormone analogue.
