Ibutamoren MK-677

What is Ibutamoren MK-677?

Classed as a selective androgen receptor modulator (SARM) due to its effects, Ibutamoren is a mimic of a growth hormone secretagogue (GHS) that can give gym enthusiasts and bodybuilders several advantages. While MK-677 was initially used to treat health conditions such as muscle wasting and obesity [1], this powerful SARM can also be used to achieve fitness goals. 

MK-677, which is also knowns as Nutrobal, works by impacting components of the brain, mimicking a GHS, and triggering a number of changes that impact metabolism, muscles, and bones. Research indicates that Ibutamoren can increase muscle mass [2], reduce fat by increasing metabolism [2], improve body composition [2], increase bone mass [3], and improve sleep quality [4].
