Train each muscle group 1x/week. It's all the body needs if you're training correctly, IMO. As for the question on EQ instead of Deca, that's the reason I use EQ. Less bloating... and try Nolvadex during your cycle. It should minimize your water retention.... (Someone correct me if I'm wrong...still learning here...)
Btw, I always train Bi's and Tri's on the same day... Love the pump I get!
