Thanks everyone for all the free information on here. I am finishing up my cardarine GW and Ostarine MK2866 cycle and very happy after 8 weeks. I went through 1 bottle of the Ostarine and 2 bottles of the cardarine, dosages were 20mgs for GW and 25mgs for Ostarine. I added 5 pounds of lean muscle. Do I still need a PCT since I only added that much weight.
