Description
MK-677 (Ibutamoren) is a non-peptide small molecule that activates the growth hormone secretagogue receptor (GHSR-1a) through the same Gq/11-coupled calcium signaling cascade as endogenous ghrelin, stimulating pulsatile GH secretion from anterior pituitary somatotrophs and downstream IGF-1 production. Its oral bioavailability and long half-life of approximately 24 hours distinguish it from peptide GHSR-1a agonists such as Ipamorelin and the GHRP series, which require parenteral administration. Capsule format is the mechanistically appropriate delivery method for MK-677 in research models examining sustained GHSR-1a receptor engagement and GH pulse dynamics through oral administration.
Storage and Handling
