Ipamorelin (IPA) is a selective growth hormone–releasing peptide (GHRP) that stimulates the pituitary gland to release natural growth hormone (GH). Known for its mild and targeted GH stimulation, Ipamorelin provides strong anabolic and regenerative benefits while minimizing side effects such as cortisol or prolactin elevation. It is widely used in research on muscle growth, recovery, fat metabolism, and anti-aging. How It Works?
Ipamorelin binds selectively to GHS-R1a (ghrelin receptor) in the pituitary:
