Read alongside Ipamorelin
Compounds this one is commonly compared with or mistaken for. Listing a pairing is not a suggestion to use them together.
- CJC-1295 (no DAC)Research use onlyOften discussed together: ipamorelin is a GHRP and CJC-1295 without DAC a GHRH analogue, acting on different receptors in the same growth-hormone pathway.
- CJC-1295 with DACResearch use onlyAlso discussed together. The DAC variant’s much longer half-life makes it a different compound from the no-DAC form, not a stronger version of it.
- SermorelinNot FDA-approvedBoth used as growth-hormone secretagogues through different mechanisms, and frequently compared on that basis.

Dose-escalation study in healthy male volunteers. Dose-proportional PK with a short terminal half-life of 2 hours, clearance 0.078 L/h/kg, Vss 0.22 L/kg. Confirms the 2-hour half-life used here — one of the few research-only entries here with genuine human PK.
