MK-677, also known as Ibutamoren, is a growth hormone secretagogue that is highly popular among athletes and bodybuilders. It is one of those compounds that is often referred to as a SARM, while it actually isn’t a Selective Androgen Receptor Modulator at all.

Ibutamoren is actually a selective agonist of the growth hormone secretagogue. It is an orally active compound that stimulates the secretion of growth hormone (GH) and insulin-like growth factor 1 (IGF-1).

Compared to other growth hormone secretagogues which are mostly peptides such as GHRP-2, GHRP-6, Hexarelin, and others, MK-677 has not been shown to increase cortisol levels.  This property makes it a unique and impressive compound.

Benefits of MK-677

Increase lean muscle mass

Ibutamoren increases GH and IGF-1 secretion. Both hormones are well known for their anabolic effects. Therefore MK-677 can increase lean muscle mass or help to maintain muscle waste, depending on caloric intake and some other factors. It can be beneficial in the treatment of catabolic conditions.


Another benefit associated with increased growth hormone and IGF-1 levels is the possibility to increase bone density. The loss of bone mass is a common issue at a later age in life or as a result of many medical conditions. MK-677 has the potential to drastically decrease bone loss. This effect is proven in numerous scientific studies.


Growth hormone plays an important role in the quality of sleep. Ibutamoren improves sleep quality, especially REM sleep when most recovery takes place. Improved sleep quality is known from scientific studies but is also an effect that is much reported by users.

MK-677 FOR FASTER Recovery

One important effect of heightened growth hormone levels is a decrease in the time needed for recovery to take place. Issue regeneration is improved which translates to an increase in the healing of tendons as well as skin and nails.


Since MK-677 shares a lot of similar qualities to Ghrelin and binds to its receptors, it is believed that MK 677 can have the same effects on the brain that Ghrelin has. Ghrelin is known to have nootropic effects, including a positive effect on cognitive functions.


The most common side effects associated with the use of MK-677 are increased appetite, mild lower extremity edema, and muscle pain.

It can also increase blood sugar, which is a risk for people with diabetes or high insulin sensitivity. These side effects are common when growth hormone levels are elevated.
