I like the advice you've been given already, but I'll add my two cents...
Your supposed to, in theory, use twice your bodyweight in Deca. After that is when the side effects pick up and outweigh the good at times. Unless your 300 pounds, I wouldn't recommend 600mgs of Deca. Also as stated above, Test is the big deal in this cycle. Your using Deca and Winny, two big natural testosterone suppresants. Along with the sexual side, you won't have that much energy without a good amount of Test. Clen tires you out as well a little. I'd take the advice and up your test to the 500-750 range, lower your Deca to the 400 range depending on your weight.
