MK677 SARM mechanism of action
MK677 SARM is a growth hormone receptor agonist and growth hormone secretion agent that mimics the secretory effect of the endogenous hormone ghrelin on growth hormone (GH). It does not act directly on androgen receptors, so Mk677 is not a strict SARM. But many supplement manufacturers classify it as SARM.

MK677 increases the secretion of growth hormone (GH) and islet-like growth factor 1 (IGF-1) but does not affect plasma cortisol levels.

1. Growth hormone (GH) is used in bodybuilding

Growth hormone (GH) is a potent anabolic hormone that promotes linear growth, weight gain, and systemic nitrogen retention. Growth hormone (GH) therapy has been shown to increase muscle mass in older men and promote protein accumulation in subpituitary subjects. These anabolic features suggest that it may be helpful in the treatment of catabolic patients, especially those caused or worsened by inadequate caloric intake. The anabolic effects of growth hormone (GH) have been used to partially reverse dietary energy restriction, exercise, surgical over-energy utilization, glucocorticoid excess catabolic effects and aging. Unfortunately, while recombinant human growth hormone (HGH) is available, treatment with growth hormone is expensive and requires parenteral administration. Therefore, growth hormone secretion agents such as MK677, which stimulate endogenous growth hormone (GH) secretion, are reasonable alternatives. It can help improve the body's anabolic metabolism and increase protein synthesis, thereby promoting muscle gain in bodybuilders. This is good for bodybuilders.

2. Islet-like growth factor 1 (IGF-1) is used in bodybuilding

IGF-1 is released in the liver and binds to intracellular IGF receptors, eventually leading to stimulation of cell growth (both lead to the formation of new tissues and the growth of existing tissues) and inhibition of cell death. It is a highly anabolic and anti-catabolic compound. For bodybuilders, this has many positive effects: increased nitrogen retention and protein synthesis because it is highly anabolic. IGF-1 (in the presence of sufficient protein) promotes the growth of new muscle cells, which increases the total number of cells in the muscle. IGF can also protect brain neurons, promoting the growth of new motor neurons, allowing them to learn new skills faster during use. IGF-1 is also responsible for connective tissue production, improving collagen formation, and aiding in cartilage repair. Similarly, it affects bones by aiding in bone building and repair.
