Ipamorelin
Ipamorelin is a selective growth hormone secretagogue and ghrelin receptor agonist. It is one of the cleanest GH-releasing peptides studied, with high selectivity for GH release without significant increases in cortisol, prolactin, or ACTH. Research focuses on its potential for improving body composition, recovery, sleep quality, and metabolic function.

Mechanism of Action
- Selective agonist at ghrelin/GHS-R1a receptor
- Stimulates pulsatile GH release from pituitary
- Minimal effect on cortisol and prolactin
- Synergistic with GHRH analogues (e.g. CJC-1295)
