Research Data

What Is Ipamorelin?

Ipamorelin is a pentapeptide growth hormone-releasing peptide (GHRP) that selectively stimulates pituitary GH secretion via GHS-R1a (ghrelin) receptors. Landmark selectivity research (Raun et al., 1998) demonstrated it stimulates GH release without significantly elevating cortisol, prolactin, or ACTH — distinguishing it from older GHRPs like GHRP-2 and GHRP-6.

Research Context

Selective GHS-R1a receptor agonism and pituitary GH release
Cortisol and prolactin-sparing profile vs first-generation GHRPs
Combination with GHRH analogs (CJC-1295) for synergistic GH pulse amplification
GH pulsatility and half-life studies
Bone density, body composition, and metabolic effects of GH axis stimulation
