If you're interested in trying MK-677 to improve your hair growth, it's important to understand how this drug works. MK-677 is a Growth Hormone Releasing Peptide (GHRP). GHRPs are a class of drugs that stimulate the release of growth hormone from the pituitary gland. They do this by binding to and activating receptors on cells in the pituitary gland, which then causes the release of growth hormone.
MK-677 is unique among GHRPs because it doesn't just stimulate the release of growth hormone; it also increases levels of insulin-like growth factor 1 (IGF-1). IGF-1 is a hormone that plays an important role in regulation of cell growth and regeneration. So, by increasing levels of both growth hormone and IGF-1, MK-677 can promote hair growth.
In one study, treatment with MK-677 increased hair count in people with male pattern baldness after 24 weeks. The average increase in hair count was 40 hairs per square centimetre compared to baseline. There were also improvements in other measures of hair loss, such as thickness and density.
Overall, the evidence suggests that MK-677 can be effective for promoting hair growth. If you're considering trying this drug, it's important to talk to your doctor first to make sure it's safe for you.
