MK-677, or Ibutamoren, is a potent growth hormone secretagogue with significant potential. Research has established its ability to increase GH and IGF-1 levels while combating muscle wasting and enhancing bone density to improving sleep and cognitive function.


MK-677, also known as Ibutamoren or Nutrobol, is a compound that has garnered significant attention in the realms of research and bodybuilding. It is a non-peptide growth hormone secretagogue that mimics the action of the hormone ghrelin in the body. This interaction stimulates the pituitary gland to release growth hormone (GH), which has numerous benefits for muscle growth, fat loss, and overall health.


  • Muscle Growth: MK-677 stimulates the release of GH and IGF-1, which are critical for muscle hypertrophy (growth). This leads to increased muscle mass and strength, making it a popular choice among bodybuilders looking to enhance their muscle-building efforts.
  • Fat Loss: Growth hormone has lipolytic properties, meaning it helps break down fat. Users of MK-677 often report improved body composition, with a reduction in body fat and an increase in lean muscle mass.
  • Recovery: One of the key advantages of MK-677 is its ability to improve recovery times. Enhanced GH levels help repair and regenerate muscle tissues faster, allowing athletes to train more frequently and with greater intensity without overtraining or injury.
  • Joint and Bone Health: For bodybuilders, joint and bone health are crucial due to the heavy lifting and intense physical activity involved. MK-677 supports joint health by potentially improving collagen synthesis and bone density, which can prevent injuries and support overall skeletal integrity.
