FDA-approved GHRH analog (Egrifta) for HIV lipodystrophy. Has the most extensive human clinical data in this class, including visceral fat reduction and metabolic endpoints.

GH-releasing peptides fall into two functional classes: GHRH analogs (sermorelin, CJC-1295, tesamorelin) that mimic the hypothalamic signal, and GHRPs / ghrelin agonists (ipamorelin, MK-677) that act on a separate receptor. They are often combined because their mechanisms are complementary.
How we ranked: Ordered by: (1) receptor selectivity, (2) half-life/dosing convenience, (3) human trial depth, (4) FDA status.

FDA ApprovedL4 · Strong Clinical EvidenceWADA prohibited
GHRH (1-29) fragment — the original short GHRH analog. Previously FDA-approved, now withdrawn from the US market but still available via compounding in specific contexts. Short half-life; typically dosed pre-sleep.
3
Banned from Compounding (Category 2)L3 · Emerging Clinical EvidenceWADA prohibited
Modified GHRH analog. The "DAC" (drug affinity complex) version binds albumin for a week-long half-life; the "no-DAC" version matches sermorelin's profile. DAC version flattens the pulsatile GH pattern, which is pharmacologically unusual.
4
Banned from Compounding (Category 2)L3 · Emerging Clinical EvidenceWADA prohibited
Selective GHSR agonist. Produces a GH pulse without measurable rises in prolactin, ACTH, or cortisol — cleaner receptor profile than older GHRPs. Very short half-life (~2 h).
5
Research OnlyL4 · Strong Clinical EvidenceWADA prohibited
Orally active non-peptide GH secretagogue (ghrelin mimetic). Raises GH and IGF-1 chronically. Failed Phase 3 for Alzheimer's and elderly-frailty endpoints; not FDA approved. Appetite stimulation is common.
Frequently Asked Questions
What is the strongest GH-releasing peptide?
In terms of GH-pulse amplitude, the CJC-1295 + ipamorelin combination produces synergistic GH release — the GHRH + GHRP pairing exploits two separate receptors. Tesamorelin has the most FDA-reviewed human data.
Is MK-677 a peptide?
No. MK-677 (ibutamoren) is a small-molecule non-peptide ghrelin receptor agonist. It is frequently grouped with GH peptides because it is used for similar goals and is orally bioavailable.
Do GH peptides build muscle like testosterone?
No. GH secretagogues raise GH and IGF-1 within a physiological range. Lean-mass changes in trials are modest compared to anabolic steroid effects. They are not interchangeable.
