MK-677, also known as Ibutamoren, is described in the original listing as a compound that promotes growth hormone (GH) secretion and increases insulin-like growth factor 1 (IGF-1). It is described as mimicking the action of ghrelin and binding to the ghrelin receptor (GHSR) in the brain.
The original description states that activation of GHSR can stimulate growth-hormone release and may also influence appetite and functions associated with mood, sleep rhythms, memory, and cognition.
Benefits and Results
The original listing highlights potential support for muscle development, preservation of lean mass, bone density, sleep quality, and recovery.
Muscle Support
Ibutamoren is commonly presented as an oral compound used to support lean body mass. The original listing states that its effect on GH and IGF-1 is one reason it is used by people looking to support muscle size and strength.
