Joo tämmönen se juttu oli minkä Bryan Haycock oli siinä artikkelissaan kirjoittanu.
"Green tea has compounds that block COMT. I stopped using as much green tea when I found that they were anti-androgenic. They not only block androgen at the receptor, thay also apear to downregulate androgen receptors.
Green tea is basically an anti-endocrine factor. It seems to reduce the effects of all steroid hormones. I don't mean to freak anybody out, it's just that the flavones (especially epigallocatechin gallate) are well known to reduce the actions of endogenous androgens (and estrogens) as well as even lowering testosterone levels themselves."
Mutta tosiaan voihan vaikutus olla niin vähäinen ettei sillä ole merkitystä.
