GHRP-2
Growth hormone Approved · Japan Human trials
Also called Pralmorelin, KP-102
A six-amino-acid synthetic peptide that activates the ghrelin receptor, prompting the pituitary to release growth hormone. Like ghrelin it also increases appetite, and it can raise cortisol and prolactin somewhat, so it is less selective than ipamorelin.
Why people take it
What studies report
- Reliable growth hormone release in human studies, used diagnostically in Japan
- Increased appetite and food intake
- Rise in IGF-1 with repeated use
In practice Off-label
- Chosen over GHRP-6 when appetite stimulation is unwanted
Reported real-world use, not evidence and not a recommendation.
Worth knowing: Also nudges cortisol and prolactin up. Appetite stimulation is strong enough to be unwanted for some.
Status: Approved in Japan as a diagnostic test for growth hormone deficiency. Otherwise a research compound.
