NOT FDA APPROVED

Growth-hormone-releasing hormone analog

Evidence score
66/ 100
MODERATE EVIDENCE

A real evidence base, with gaps

  • Regulatory standing. Sold as a research chemical, not approved
  • Human trials. Backed by controlled human studies
  • Registered human trials. 27 registered studies on ClinicalTrials.gov, most advanced Phase 4
  • 1 cited source. Cited references provided

A read on the weight of evidence and regulatory standing behind this compound. It is not a safety score, not a purity or quality rating, and not medical advice. It is not a claim that this compound treats, cures, or prevents any condition, and not an endorsement or a recommendation to buy or use it. A low score means the evidence is thin — not that a product is unsafe; a high score means the evidence is strong — not that anyone should take it. PLOBT is independent and takes no money from any vendor; no company can pay to change this score.

What's actually proven

Proven: it stimulates the body's own growth-hormone release and was historically approved to diagnose/treat GH deficiency. NOT established: the anti-aging and body-composition benefits it is currently marketed for.

Half-life
Short (minutes).
How it is used
Subcutaneous injection.

What it is

A GHRH analog. It stimulates natural, pulsatile GH release rather than replacing GH directly.

What the research says

Stimulates growth-hormone releaseHUMAN TRIALS

Historically FDA approved for GH-related indications before the product was discontinued.

Anti-aging / body compositionANECDOTAL

The main marketed use today. Not well established in controlled trials.

FDA recalls & enforcement

Sermorelin has no FDA recall or drug record at all — because it is not an FDA-regulated drug. That absence is not a safety signal. It means this compound is sold outside the system that inspects, tracks and recalls unsafe products in the first place.

Risks & unknowns

  • No currently approved product: quality depends on the compounding pharmacy.
  • GH/IGF-1 elevation carries theoretical growth-signalling risks.

Doses reported in studies & protocols

Compounded protocols vary. This is not a recommendation.

Purity reality

Compounded product quality varies by pharmacy.

Verified lab data

None yet. PLOBT does not publish invented purity numbers. Real third-party COA data, mapped to vendor and batch, is in development — and it is the one thing we refuse to fake.
