Ipamorelin is a selective pentapeptide growth hormone secretagogue and ghrelin receptor (GHSR-1a) agonist studied for its ability to stimulate pulsatile GH release from the anterior pituitary with high specificity and minimal off-target hormonal effects.
Unlike first-generation GH secretagogues, ipamorelin demonstrates exceptional receptor selectivity — producing robust, dose-dependent GH pulses without clinically significant elevations in cortisol, prolactin, or ACTH in research models, making it a highly controlled tool for studying the GH/IGF-1 axis.
Preclinical research has examined ipamorelin’s role in lean body mass preservation, lipolysis, bone density modulation, sleep architecture improvement, and anti-aging cellular signaling, establishing it as one of the most widely used selective GH secretagogues in peptide research.

Excellent product and great customer service. Had a question about reconstitution and the concierge team got back to me same day. Quality is exactly as advertised.
