So far my muscles feel more full and i am getting great recovery. I am eating a load, and yet still maintaining a 4 pack. The only sides ive hit so far are a few pimples on my shoulders and like 1 or 2 on my face. In comparison to mass fx where i broke out on my face and back/chest. I do feel like my skin is a little bit more oily think I had a little bit more strength gains on MFX but not as good of recovery. I think the alpha male mentality was a little bit more prevalent on mfx as well. HOWEVER im barely midway through this stack! so lets push this to beyond limitations!
