Unfortunately this guy never seems to stop, and he has the "I know everything, you are a fucking retard" mentality so telling him anything he doesn't want to hear is impossible.
We were chatting last night and he told me he purchased a Tribulus product(probably the cheapest crap he could find). So he tells me that he GAVE SOME TO HIS GIRLFRIEND. I just stare at him and he goes on to tell me:
"it makes guys produce more testosterone so in girls it makes them produce more estrogen...so she got really horny"
I pretty much wanted to punch him in the face. However I figured rather than tell him how stupid he is, I just calmly asked him to not give anymore to his girlfriend, that it's not designed for females, and if he wants to know why I would find some information to lay it out in detail(paging Cy Wilson, Cy to the front desk please). Now, granted what he got is probably garbage, and as far as I know she only took one dose, I can't imagine it did much damage, but what are the effects of prolonged use in females, if even known?
