I’ve been on LGD4033 for a couple weeks now and MK2866 for a bout a week. I know.. not the smartest stack. I’ve seen some pretty good results already but my roommate said the mk I was getting was the mk677 and when I picked it up it was 2866. I would like to switch to 677 and stop the 2866 but I don’t know if that’s a good idea and what steps to take to do so. Or if I should just finish these bottles, do a pct and then do a bulk. What should I do? If I sound like I don’t know what I’m talking about, I don’t, all I know about sarms is from threads I’ve read here and what my roommate has told me.
