- | Compound | Mechanism | Half-Life | Dosing Frequency | Peak GH Elevation | Key Research Applications ||—|—|—|—|—|| Ipamorelin | GHSR-1a agonist (GHRP) | ~2 hours | 2–3× daily | 5–8× baseline | Selective GH release without prolactin or cortisol elevation. Cleanest GHRP profile || Hexarelin | GHSR-1a agonist (GHRP) | ~70 minutes | 2–3× daily | 8–12× baseline | Most potent GH release per dose. Some studies note desensitization after 4–6 weeks || CJC-1295 (no DAC) | GHRH analog | ~30 minutes | 2–3× daily | 3–6× baseline | Synergizes with GHRPs. Amplifies pulse height when co-administered || CJC-1295 DAC | GHRH analog with albumin binding | 6–8 days | Once weekly | 2–4× baseline sustained | Continuous low-level GH elevation. Mimics tonic secretion rather than pulsatile || MK-677 (Ibutamoren) | GHSR-1a agonist (oral) | 4–6 hours (24h GH elevation) | Once daily | 3–5× baseline over 24h | Oral bioavailability, sustained elevation, appetite stimulation via ghrelin mimicry || GHRP-2 | GHSR-1a a
