It hasn't caused any bloat yet, I keep my diet very clean and do not drink any sodium beverages or eat salt etc. I drink a lot of water and the only thing I take on the side is N2GUARD. I havent gotten the bloat yet, was just a little scared that it might happen, my last cycle was 500mg test e a week with a not that good of a diet, then I got pretty bloated, but now I only do 100mg test E4D. I just hope the tren ace will give me a shredded look after some more time on it now, and not the test e will ruin it or something.
