What Is MK677?

MK-677 is a growth hormone secretagogue designed to mimic growth hormone treatment in an effort to treat catabolic patients (patients with diseases that reduce mass).

Application Of MK677

A human trial that went through a quick treatment of MK-677:

“[MK-677] increased the mean IGF-I concentration significantly to 264 ± 31 ng/mL (mean for the last 5 days of treatment) compared with 188 ± 19 ng/mL with placebo (P < 0.01).”*
What this means is that patients who use MK-677 can see a SIGNIFICANT increase in IGF-1 promoting drastic changes in fat mass (reduction) and muscle mass (increase).
Lastly, “neither the serum cortisol nor the PRL response was significantly greater after 7 days of MK-677 dosing compared with 7 days of placebo.”*
