Ive run this stack many times. As stated by other is typically keep the Rad140 in the 20mg range occasionally going to 30mg a day. GW always at 20mg/day dont go higher.
If you add in MK2866 which I love run that starting at 25mg/day and can up to 50mg/day if you want. Ive run both and had better results with no sides that i can see through feel or bloodwork.
