I have tried Tren Hex and Enathate, I could'nt tell much difference between the two, ran both of them at 500mg/Wk with freaky results, as for Ace, most say it gives the best results but to get the most out of it you need to shoot it ED and I'm a puss , twice a week is what I'm used to and i don't look forward to that,its all in what you want.....
