Subject starting to see some size. It may just be from all the eating. It definitely increases appetite. Not a big change in strength. Been testing for 2.5 months

After a cycle of MK2866 I ran MK677 with a PCT (30mg) and put on another 10lbs (current weight 270lbs). You have to watch the food intake (since I noticed an increase in appetite) but would run this again at some point.
