What Ipamorelin is
Ipamorelin is a pentapeptide growth-hormone secretagogue. Unlike earlier compounds such as GHRP-6, it shows little effect on cortisol or prolactin in the published studies, which is why researchers describe it as selective.
It is often combined with a GHRH analogue such as CJC-1295, because the two act on different receptors in the GH axis.
What the research literature studies
- Ghrelin-receptor binding and selectivity
- Comparison with other GH secretagogues
- Combination signalling with GHRH analogues
Evidence rating: 2/5
Mostly animal and in vitro. A small number of human studies. Never approved. See our methodology for how levels are assigned.
- A phase 2 trial in another indication did not meet its primary endpoint.

Ipamorelin FAQ
Why combine ipamorelin with CJC-1295?
They activate two different receptors on pituitary cells. Researchers study the combined signal because the pathways converge on GH release.
