Research has shown that MK-677 amplifies chemical signals directed to the pituitary gland to secrete growth hormone increasing overall growth hormone and it also acts to slow the release of somatostatin which essentially turns off the release of growth hormone. Because its powerful androgenic activity it essentially changes the way androgen receptors function thus giving it comparisons to real anabolic steroids with many less side effects. MK-677 increases not only muscle mass but also bone density and is shown to increase fat loss. Research has shown that MK-677 can also improve endurance partially because it chemically stimulates a hormone known as ghrelin which is responsible for the distribution and rate of energy use. IGF-1 which aids in protein synthesis among other things is also released at an increased rate with MK-677. Above all MK-677 acts on various different hormonal plasma levels for sustainable long lasting increases. With very little side effects MK-677 produces many great benefits with endurance,lean mass,fat loss,increase in the healing ligaments and tendons,tightens loose skin,and promotes an overall sense of well-being.
