Sermorelin Research Peptide

Sermorelin is a growth hormone-releasing hormone analogue. This topic brings together its molecular identity, historical clinical use, evidence, and comparisons.

TOPIC OVERVIEW

About Sermorelin

Identity and names

Sermorelin is also described as sermorelin acetate or GHRH(1-29). Product names and salt descriptions require context rather than being treated as interchangeable materials.

Compound type

It is a synthetic analogue corresponding to the biologically active first 29 amino acids of human growth hormone-releasing hormone. It is distinct from growth hormone itself.

Mechanism

Sermorelin acts through the GHRH pathway to stimulate pituitary growth hormone release. This mechanism differs from the ghrelin-receptor pathway used by Ipamorelin.

Research focus and evidence

Historical research and clinical use include growth hormone diagnostic testing and pediatric growth hormone deficiency. That evidence does not establish every adult wellness or anti-aging claim.

Regulatory status and limits

GEREF had specific historical U.S. approvals; approval was later withdrawn following discontinuation. FDA subsequently determined that the products were not withdrawn from sale for safety or effectiveness reasons. This history does not confer approval on other formulations.

Topics covered
  • GHRH and growth hormone signaling
  • historical diagnostic and pediatric evidence
  • product and formulation distinctions
  • comparisons with related secretagogues
  • storage and research limitations

RESEARCH SUMMARY

What Is Sermorelin?

LAST VERIFIEDOctober 7, 2026

Sermorelin is a 29-amino-acid GHRH analogue with historical diagnostic and pediatric clinical uses. A published clinical review describes the growth hormone response and the scope of studies in children with idiopathic growth hormone deficiency. Its conclusions apply to that clinical context rather than serving as proof of broad adult benefits. Clinical review of pediatric and diagnostic use

FDA records distinguish discontinuation from a finding of unsafe or ineffective treatment. Its 2013 determination states that the specified GEREF presentations were not withdrawn from sale for safety or effectiveness reasons, while noting the earlier withdrawal of their approvals. This does not establish approval or equivalence for compounded or research-labeled preparations. FDA GEREF determination (2013)

CLINICAL REGISTRY

Selected registered research

No matching intervention record was found in ClinicalTrials.gov during this verification. This does not mean that no research exists.

How to interpret this profile

Registry and publication counts describe discoverable records, not proof of effectiveness or safety. Study design, compound identity, population, endpoints, and regulatory context must be reviewed individually.

Primary sources: ClinicalTrials.gov · PubMed (defined query)Snapshot checked October 7, 2026. Registry counts include only explicit intervention names/aliases, not fuzzy search totals, biomarker measurements, or related compounds. Active means recruiting, not yet recruiting, active not recruiting, or enrolling by invitation. PubMed counts use the displayed title/abstract query and are search matches, not a curated count of treatment trials. Sermorelin/GEREF/GHRH(1-29) search returned 42 broad matches; none explicitly named these as an intervention. Older unregistered human studies remain relevant.

Displayed records are selected for relevance and recency; the page does not reproduce the complete source databases.
