MK-677, also known as Ibutamoren or Oratrope, is an orally active and selective agonist of the ghrelin receptor. Preclinical research suggests it may stimulate the natural secretion of growth hormone (GH) and insulin-like growth factor 1 (IGF-1) without significantly affecting cortisol levels. Studies in animal models have explored its potential in growth hormone-related pathways, including muscle and bone health, appetite regulation, and neurological research. Research in mice has indicated its potential to influence Alzheimer 's-related mechanisms when administered before significant amyloid beta accumulation. Additionally, MK-677 has demonstrated promising effects on sleep quality in experimental settings. This compound is strictly for research purposes, supporting investigations into metabolic, musculoskeletal, and neurological mechanisms.
