( — December 16, 2021) — MK-677 is a compound that was originally designed for treating adults with growth hormone deficiency under the brand name Ibutamoren. A study involved 33 male and 34 female participants, aged 18–55 years old, who had normal levels of IGF-1 (insulin-like growth factor 1). They were given the growth hormone peptide MK-677 as a daily orally administered dose or a placebo under double-blind conditions for 3 months.

Of the participants, 21 were in the treatment group and 22 were in the control group. The results show that there was no change in body weight between groups, but there was a significantly increased lean muscle mass by 1.7 kg and reduced fat mass by 1.6 kg in the treatment group than the control group. There were no effects of MK-677 on lower body strength or aerobic capacity, but it did significantly improve upper body strength and stair-climbing power. Serum IGF-1 levels increased by 61% in the treatment group compared with 4% in the control group.

The research that prompted this study was done by independent researchers rather than Merck but is still listed as Merck in PubMed. 


MK-677 works to improve sleep and the treatment group reported waking less often during the night and needing less time to fall asleep than those receiving a placebo, but this was only significant in men. The treatment group tried to eat significantly more calories per day than those receiving a placebo, which lead to an increase of weight by 2.2 kg, but body composition was still significantly better than the control group. Bone mineral density increased by 2.6% in the spine and by 1.4% in the femur in the treatment group, whereas there was no significant change in either measure in the control group.

So overall, MK-677 seems to be effective in increasing lean muscle mass and reducing fat mass, while also having positive effects on bone density, sleep, and caloric intake. It was safe and well-tolerated for the study participants. There are still some unknowns about MK-677 such as its long-term effects, but the initial results are very promising.

MK-677 has been found to be an extremely beneficial compound for a variety of reasons. It can help increase lean muscle mass and reduce fat mass, while also having positive effects on bone density, sleep, and caloric intake. It is safe and well-tolerated in humans, and further research is needed to determine its long-term effects. For now, MK-677 appears to be a promising compound for possible therapeutic benefit.
