NEO SARMs MK-677 (Ibutamoren) operates as a selective agonist of the ghrelin receptor (GHS-R1α), functioning primarily as a growth hormone secretagogue. By mimicking the endogenous hormone ghrelin, MK-677 stimulates the release of growth hormone (GH) from the pituitary gland. This stimulation results in elevated levels of both GH and insulin-like growth factor 1 (IGF-1) in the […]
