taking testostarone tablets and aa tablets

Hi All,

My little brother wanted to know if taking testostarone tablets (tribilus or triandabol) please see link of product:

would make you more hairy. He is worried about facial vellus hair becoming more noticable if he takes these for body building. He also wanted to know if amino acid tablets (Melibol BCAA 2200) could make you more hairy. Your response would be much appreciated.
