Hexarelin: what it is, what the evidence says, and its real status
A potent ghrelin-receptor GH-releasing peptide from the legacy bodybuilding toolkit, restricted, with prolactin and desensitization issues.
Short version: an older, potent GH-releasing peptide with real downsides (prolactin, receptor desensitization). WADA-banned and restricted, education only.
Can you actually get it?
Plain-English verdict: Education only.
Regulatory status: Restricted · research-only · Education only.
Not available to prescribe. Hexarelin is a research-only GH-releasing peptide, restricted and prohibited in sport (WADA S2). Not FDA-approved, not compoundable, education only; the legal GH-axis answer is Sermorelin.
How does Hexarelin work?
A potent ghrelin-receptor agonist that triggers a strong pulse of growth-hormone release.
What it does — and what it does not do
What it does: Raises growth hormone strongly; used historically in performance circles.
What it does not do: It is not approved or available, and tolerance plus prolactin effects limit its usefulness.
How honest is the evidence?
Evidence grade C — older human GH data; desensitization and prolactin concerns. Read our grading methodology for what each grade means.
What we still don't know: Long-term endocrine effects and the desensitization curve are poorly characterized.
WADA status: Banned (S2).
How it is taken
Not offered; education only.
Who should not take it
WADA S2 banned; prolactin elevation; not characterized for safe human use.
