Overview

Selective growth hormone releasing peptide (GHRP) that stimulates GH release without significantly affecting cortisol, prolactin, or ACTH — making it one of the cleanest GH secretagogues. Frequently combined with CJC-1295 (no DAC) for synergistic effects. Requires reconstitution with BAC water.

Mechanism of Action

Selective ghrelin/GHS receptor agonist on the anterior pituitary. Unlike GHRP-2 and GHRP-6, it does not significantly stimulate appetite or raise cortisol/prolactin.
