I don't think you're thinking about testing, you just want info on which test to use to look the hardest. Let me advise you bro that more than your test , your diet is going to be crucial to obtain this, so fine tune that, and there is plenty of info on dieting on the board. Stay away from suspension , the stuff will make you bloat like if you had your period. Different things work for different people, for me the best combo to use to look the hardest is Test prop, Masteron, Winstrol, now that is if your BF is low enough already, I would start this three weeks out, also up your cardio, and I would run this up to the day of contest, The problem with this is the constant pinning , I run this like this, 100 mgs of prop, 100 mgs of Masteron ED, 50 mgs of oral Winny ED. Now there might be guys that disagree with me , and others will agree, but this stack has gotten me the best look, and it comes with little side effects. God bless you and good luck, keep us posted.
