Evidence brief
Sermorelin
Written and source-checked by Anthony Treviso, founder of The Peptide Field.
Direct answer
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.
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.
- How strong is the evidence?
- Emerging
Some studies in people exist. Important questions remain about benefit, safety, who it helps, or how long the effects last. This is not an approval or recommendation. - What evidence exists?
- Human pharmacology only
Studies in people measured how the substance changed the body. This did not establish a health benefit on its own. - Sports rules
- Prohibited
The checked rules list this substance or group as prohibited under the stated conditions. Check the current rules for your sport.

01 · Evidence profile
Four questions about the evidence
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.
02 · Identity
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 In 2013, FDA said the products were not withdrawn for safety or effectiveness.
Scientific group: Growth hormone-releasing hormone analogue. This group name describes the type of molecule or body signal. It does not prove a benefit, safety, or approval.
03 · Exact product
The molecule is not the finished product.
Formulation: The finished product's ingredients and physical form. Route: How the product enters the body. Indication: The approved or studied use and group of people for a product.
None identified in the United States.

04 · Research results
What the research shows
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.
Exact product
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.

Claims I checked
3 claims checked for this brief.
“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.
- Evidence used
- Regulatory or product record. This answer uses an official regulator record or a specific product label.
- Limits of this answer
- Historical Geref products, not current compounded sermorelin. This answer covers only the named molecule and finished product. It also covers the product form and how people used it. The study limits include who took part, what was used for comparison, what changed, and how long the study lasted.
“Sermorelin raises growth hormone, so it is proven to slow aging.”
A hormone response cannot show that people live longer or age more slowly.
- Evidence used
- Human pharmacology. This answer uses a study of how the substance enters or changes the body in people. This alone does not show a health benefit.
- Limits of this answer
- Hormone-response evidence cannot establish longer life or slower biological aging. This answer covers only the named molecule and finished product. It also covers the product form and how people used it. The study limits include who took part, what was used for comparison, what changed, and how long the study lasted.
“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.
- Evidence used
- Regulatory or product record. This answer uses an official regulator record or a specific product label.
- Limits of this answer
- Current products marketed after Geref withdrawal. This answer covers only the named molecule and finished product. It also covers the product form and how people used it. The study limits include who took part, what was used for comparison, what changed, and how long the study lasted.
