MK-677, also known as Ibutamoren, is a non-peptide ghrelin receptor agonist that has been extensively studied for its ability to stimulate endogenous growth hormone (GH) and IGF-1 release through GHSR (Growth Hormone Secretagogue Receptor) activation.
Unlike injectable peptides such as GHRP-6 or Ipamorelin, MK-677 is orally bioavailable, making it a valuable tool in long-term research models where daily GH pulsatility and downstream anabolic effects are studied.
Research has explored its role in:
Muscle preservation and lean mass increase
Bone density enhancement in aging models
GH and IGF-1 modulation without affecting cortisol
Sleep quality and recovery enhancement in animal studies
Investigations into age-related hormone decline and sarcopenia
Studies of GH/IGF-1 axis modulation
Models of nutritional deficiency, wasting, and recovery
Exploration of neuroendocrine and metabolic signaling pathways
Store capsules in a cool, dry, light-protected environment at room temperature.
Ensure cap is tightly sealed to prevent exposure to moisture.
