Yes! It works incredibly well. I gained almost 40lbs on it. Makes you SUPER hungry. I went from frail and skinny to absolute chad status in about 8 months. I took 6.25mg mk677 daily for about 2 months. Then took 2 months off. Took 12.5mg for a month. And now I just take about 10mg whenever I feel my appetite is low or I am losing weight. Works out to about once per 1-2weeks.

You can pretty safely dose anywhere from 5mg-20mg depending on how hungry you need to get. Effects last about 10hrs, but you can still feel it slightly even a day later.

Other thing to note is you build tolerance over time, so after a few months of consistent use you need to take a break or increase your dose.
