Ipamorelin — molecular reference
Ipamorelin is a synthetic pentapeptide and a highly selective agonist of the growth hormone secretagogue receptor (GHSR-1a, ghrelin receptor). Its selectivity relative to broader GH-secretagogues makes it a common tool compound in cultured somatotroph and pituitary-cell models, particularly for parallel GHSR-1a receptor engagement and downstream cAMP / IP₃ signaling without prolactin or cortisol confounders. Supplied as a sterile lyophilized powder for reconstitution in bacteriostatic water. For laboratory research use only — not for human or veterinary use.
