Reviewed by Fat Man in the Arena · Updated March 2026
How Ipamorelin works
Selectively binds to the ghrelin/GHS receptor in the pituitary gland to stimulate natural growth hormone release in a pulsatile pattern. Unlike other GHRPs, it does not significantly increase cortisol or prolactin levels.
Reported benefits
Based on available research data, Ipamorelin has been associated with the following benefits:
- Increased growth hormone release
- Improved body composition (less fat, more lean mass)
- Better sleep quality
- Enhanced recovery from exercise
- Minimal side effects compared to other GH secretagogues
- Does not significantly raise cortisol or prolactin
Supporting research
Ipamorelin, the first selective growth hormone secretagogue
European Journal of Endocrinology, 1999 · PMID: 10580762
Ipamorelin demonstrated selective and potent GH release without affecting cortisol, ACTH, prolactin, or FSH/LH levels, making it the most selective GHRP studied.
