I have no baldness in either side of my family, my father, uncles, and grandfathers all have full heads of hair. D-bol never did anything along those lines, but winny did. My hair started looking thinner and at first I thought I was just paranoid. Then every morning while on it my pillow would have hair all over it. It also gave me terrible acne on my chest that took monthes to get rid of. After I stopped winny, my hair went back to normal and got thick again. I'll never touch that shit again.
