Ipamorelin
Analytical Standards & Laboratory Handling
Verified laboratory protocols, reconstitution parameters, and handling guidelines.
Pharmacological Profile & Mechanism of Action
What it is: Ipamorelin is a synthetic pentapeptide (Aib-His-D-2-Nal-D-Phe-Lys-NH2) that belongs to the Growth Hormone Secretagogue (GHS) family and acts as a selective ghrelin receptor agonist.
How it works: It selectively binds to the ghrelin/GHS-R1a receptor in the pituitary gland, triggering clean, natural pulses of growth hormone (GH) that closely mimic the body's natural youthful secretion patterns. Remarkably, unlike older GHRPs, Ipamorelin does not stimulate cortisol, prolactin, or ACTH, and causes minimal hunger spikes.
Why researchers study it: Studied for deep slow-wave sleep enhancement, lean muscle preservation, accelerated wound and bone healing, body fat reduction, skin collagen synthesis, and anti-aging without hormonal side effects.
Compound & Molecular Specifications
Certificate of Analysis StandardsFrequently Stacked with Ipamorelin (GHRP Selective)
Clinically verified combinations activating complementary physiological pathways without receptor competition.
CJC-1295 No DAC (Mod GRF 1-29)
CJC-1295 (GHRH agonist) stimulates the synthesis and transcription of Growth Hormone in pituitary somatotropes, while Ipamorelin (selective GHSR agonist) suppresses somatostatin and triggers the vesicular release pulse. Together they produce an amplified physiological GH pulse up to 5x higher than either alone.
Tesamorelin (GHRH Analogue)
Tesamorelin selectively targets visceral abdominal fat while stimulating pituitary GH transcription; Ipamorelin triggers vesicular release without elevating prolactin or cortisol.
