Positive experiences
“From my own experience (also have suffered from poor sleep), i experienced a noticeable increase in sleep quality even with a low dose.”
“I've tried mk677 and it supposed to pharmacologically improve rem sleep and allowed me to get away with less sleep.”
“I ran 25mg mk677 and 10mg LGD 4033 for 3 months and I gained 9.5kg but my body fat stayed the same.”
“Amazing sleep with mk 677. I track my sleep with an App on my Apple Watch. It almost doubles my deep sleep.”
“MK-677 @ 25mg for 6 months is a pretty standard and effective plan, and I know more than a handful have run it for the skin and anti-aging benefits with good results.”
“I went from 72kg / 159lbs ( 17.6% Bodyfat ) ➡️ 76.5kg / 169lbs (14.5% Bodyfat )... No side effects, no crazy hunger... felt well overall.”
Negative and mixed experiences
“MK-677 lately... The sleep that it gives me is extremely fragmented and the total sleep time is reduced. But during the day I feel like I've had a better than average nights sleep.”
“It worked! My nausea and sickness was quickly replaced with an extreme hunger.”
“MK677 had some conflicting effects for me. On one hand, hunger pangs all the time, water weight... On the other hand, sleep and recovery were incredible.”
“My own experience (so far) with 20mg/day is I have not had a massive increase in hunger...retained some fluids right away and gained a quick 4 lbs but that seems to be normalizing already (two weeks in).”
“Mk-677 gave me some serious water retention and fatigue, it doesn't happen to everyone though. Huge impact on the quality of my sleep, in a good way.”
“I took mk677 and the only real effect I felt was more hunger which made me gain a lot of weight. So good for bulking. Didn't tell a difference on recovery or sleep.”
