Description
Ipamorelin is a synthetic pentapeptide and selective agonist of the ghrelin/growth hormone secretagogue receptor (GHS-R1a), notable in the research literature for its high specificity in stimulating pituitary growth hormone release while exhibiting minimal off-target effects on cortisol, prolactin, FSH, LH, or TSH secretion compared to earlier secretagogue compounds. Supplied as a purified lyophilized powder in sealed 10mg vials, each batch is independently verified by third-party laboratories via HPLC/UPLC-MS with 99%+ purity and bacterial endotoxin results documented per lot. Storage in cool, dry conditions is recommended for lyophilized material; following reconstitution, the solution should be refrigerated at 2–8 °C.
Ipamorelin has been widely employed in preclinical research investigating the somatotropic axis, including studies on pulsatile GH release dynamics, IGF-1 signaling, body composition modulation, and the potential intersection of GHS-R1a pharmacology with bone density, lean mass accretion, and metabolic rate in animal models. Its favorable selectivity profile makes it a preferred reference compound for researchers seeking to isolate GH secretagogue effects from adrenal or lactotrophic confounders in experimental designs. For laboratory research use only. Not for human or veterinary use.
