i have literally covered this like a million times... lets do it again
GW is going to protect you from cortisol, which is your biggest enemy in pct along with estrogen... when your cortisol increases, not only will you add unwanted fat but your in a huge catabolic state... you CANNOT add muscle either with a cortisol increase and your going to lose all of your gains from your cycle... By using GW-501516, your preventing this from occurring...
