I agree with you. Estro does become an issue for many. Ive managed to keep my estro around 30-40 with the doses of test i run and its because ive been taking .25mg adex every day for all these years. I havent had any sides from the adex in my bloodwork that people claim adex causes. And it all depends what your goals are too. i just know from experience i feel and look better on 600mg test than 200mg test and the higher doses have not effected my bloodwork in any negative way. in fact my bloodwork now is better than it was in my 20s. and i contribute that to my extremely disciplined diet.
