So when I took mk677 it was for hunger. The first day it worked perfectly. I was hungrier than i’d been in months. Then by day 3-4 it started decreasing and by the end of the week it was right back to where it was before but with an added benefit of feeling more lethargic. 0 hunger. Then I got off the mk and the lethargy went away. I wouldn’t use it again. There are old allergy medications and weird stuff that coaches like Chad nicholls has used on clients but to be honest, if you want to get really big, you’re going to need to force food, feel nauseous, maybe throw up, and just repeat that over LONG periods of time. MK677 doesn’t help in my experience aside from the very short term
