Ipamorelin

Ipamorelin is a synthetic pentapeptide and highly selective growth hormone secretagogue (GHS) that acts specifically on the GHS-R1a receptor. Unlike other GHRPs, it selectively stimulates pituitary GH release without affecting other hormones like ACTH, cortisol, prolactin, FSH, LH, or TSH, even at doses up to 200× the ED50 for GH.

  • Selective GH Stimulation: Stimulates GH without raising cortisol, ACTH, prolactin, or other pituitary hormones
  • Physiological GH Release: Maintains natural pulsatile patterns; mimics endogenous GH cycles
  • Reduced Injection Frequency: Longer half-life allows fewer injections compared to GHRP-2 or GHRP-6
  • Safety Profile: Mild, transient side effects; lower risk than non-selective GHRPs
  • Tissue Repair & Recovery: GH-mediated pathways may enhance wound healing, recovery from injury, and anabolic signaling
  • Body Composition: Potential benefits via GH/IGF-1 pathways (lean mass, fat metabolism)
  • Sleep Architecture: May improve slow-wave sleep indirectly through GH release (animal data; limited human studies)
  • Metabolic Effects: Potential glucose and lipid metabolism benefits via GH pathways (preclinical/animal data)
