I know your not a big fan of anti-estrogens and regardless what anyone thinks, even when on a boat load of anti-e's the average cycler here will still have significantly elevated estrogen. Is estrogen essential? Sure it is, but at the same time men, generally speaking can not handle 10x the amount of estrogen nearly as easily or sidefree as they can 10x normal androgen levels.
No offense Nelson but you used to come at this issue by toughting lower dose cycles but ever since you busted into the suppliment biz your focuse seems to be more cuppliment and hence profit driven.
