One of the substances that has received increasing attention in recent years is MK-677, also known as Ibutamoren. Although it is often mentioned in the same context as SARMs (Selective Androgen Receptor Modulators), MK-677 is not officially one of them. It is a growth hormone secretagogue, which means that it stimulates the natural production of growth hormone in the body.
