What is Ibutamoren MK-677?
Ibutamoren, also identified as MK-677, MK-0677 or L-163,191, is an investigational, orally active, non-peptide growth-hormone secretagogue. It acts through the growth-hormone secretagogue receptor, also known as the ghrelin receptor or GHSR1a. MK-677 is not human growth hormone and is not a selective androgen receptor modulator.
Commercial descriptions frequently associate MK-677 with muscle development, recovery, sleep quality, appetite or changes in growth-hormone and IGF-1 levels. These statements should not be presented as guaranteed, medically approved or clinically established benefits of this commercial capsule product.

Safety and regulatory information
Ibutamoren is an investigational compound and should not be presented as an ordinary dietary supplement or approved medicine. FDA enforcement materials have classified products marketed with MK-677 for human performance-related purposes as unapproved new drugs in the United States.
Long-term safety has not been established. Reported concerns include fluid retention, changes in fasting blood glucose and insulin sensitivity, increased appetite, swelling, muscle or joint discomfort and potential cardiovascular or hormonal effects. FDA-related safety information has also identified a potential risk of congestive heart failure in certain patients.
The presence of a capsule format, serving information or a “Supplement Facts” panel does not establish that Ibutamoren is an authorised food ingredient or an approved medicinal product.

Ibutamoren MK-677 is included on the World Anti-Doping Agency 2026 Prohibited List among growth-hormone secretagogues and their mimetics. Athletes and other individuals subject to anti-doping testing should treat the product as prohibited at all times.
