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.

Great product, subject started off with 2 caps, to one a day before bed for 2 weeks. Then went back to two caps before bed. The reason for that was lethargy during the day from starting off with 2 caps. Now the 2 cap dosage has no lethargy. GTG!!!

This is by far one of my favorite research chemicals even though it technically isn’t a SARM, it does not suppress GH and does not need to be cycled, expect better quality sleep, an increase in appetite, and a slow and steady increase in strength and muscle mass. Sarmtech’s triple lab testing guarantees that what the label says is what you are truly getting and the 15mg dosage is a perfect starting point for any research study. I would highly recommend Sarmtech to anyone looking for high quality research chemicals.
