I'm about 1.5 weeks into a Test Enanthate/Winstrol cycle and I'm getting progressively more painful back pumps. I get it anytime my back is not relaxed, so pretty much anytime I'm standing. I could barely stand-up after squats and had to cut the workout short. I've seen others have experienced similar problems while 'on' but I didn't find anything saying how to alleviate the problem. Anyone have any luck? I tried eating a ton of bananas for potassium but it didn't do anything. Stretching = nothing. Warm baths = nothing. Anything else?
