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.

Important context
