MK-677

MK-677, also known as Ibutamoren, is a growth hormone secretagogue that stimulates the release of growth hormone and insulin-like growth factor 1 (IGF-1). It is primarily used to enhance muscle growth, bone density, and overall body composition, which are important for longevity and health optimization. Its ability to increase growth hormone levels without affecting cortisol levels makes it a promising compound for anti-aging purposes.
