Ipamorelin

Q: Why is ipamorelin called "selective"?

Compared to GHRP-2 and GHRP-6, ipamorelin produces minimal increases in cortisol and prolactin while still stimulating GH release, making it a cleaner signal in GH axis research.

Q: Is ipamorelin often paired with CJC-1295?

Yes. Ipamorelin (a GHRP) is frequently studied alongside CJC-1295 (a GHRH analog) in research exploring synergistic GH pulse stimulation.

Ipamorelin (Selective GHRP)

Research Use Only · Not for Human Consumption

Ipamorelin is a pentapeptide (5 amino acids) that acts as a selective growth hormone secretagogue. It binds to ghrelin receptors (GHSR-1a) in the pituitary and hypothalamus, stimulating GH pulse release. Ipamorelin is notable for its selectivity — research shows it does not significantly elevate cortisol, prolactin, or ACTH at typical research doses, distinguishing it from older GHRPs like GHRP-2 and GHRP-6.
