I am no biochemist, but the way I understand it is that the body attempts to keep one’s test levels in check with estrogen. So as your natural test levels rise or fall, so goes your natural estrogen levels. If this is true, than does taking supplements like Carbolin 19 or Alpha Male make sense, without taking an estrogen inhibitor as well? And for that matter, could one take an estrogen inhibitor and get the same effect with their natural test production?
And for a follow up, does anyone even make a legit est blocker?
Limiting your environmental exposure to Oestrogen’s will help and through dietary manipulation. Firstly avoid tap water and Soy. Secondly cruciferous vegetables contain Indole 3 carbinol which is a naturally occuring anti-oestrogen.
There are things to limit oestrogen activity, but oestrogen activity can be specific, for example in gyno. Non-legit methods are things like Nolvadex (Tamoxifen) which is known as a SERM (selective (o)estrogen receptor modulator). This is used in the treatment of breast cancer. All it does, as do most anti-oestorgens is take the place of oestrogen at receptor sites.
Some anti-oestrogens are in fact weak oestrogens. But, Commercially available ones aimed at bodybuilders cite acitivties like suppressing endogenous oestrogen activity and stuff, rather than acting more directly.
