I've heard that, tried that, and found it untrue (for me). Maybe if crushing SHBG and the like is thrown into the bag, otherwise the body is going to neutralize that shit anyway, and fucking A the side effects surely do go up.
I have been up to a gram and a half without any anti A though, where in the past I needed it ~600mg a week. The human body adapts, I found no magical shortcut. I still prefer lower doses and stacking. :shrug:
I know several guys who would put almost everyone here to shame and they are on low dose shit, rookies run more than them. I also remember a first time cycler who started out at 2 grams a week, thinking it was the hot ticket. Now he wont even touch the shit his experience was so bad.
