As a 19 year old guy, what will taking zinc pills do to my testosterone levels?

So I don't need it but I noticed guys taking steroids and testosterone but I decided why not go to the source, and i have been taking zinc capsules for about a month now, and i have noticed faster growth of my bodily and facial hair. I dont know if this is just the normal process of my body, since im 19. but if you guys can tell me if its also because of the zinc and what its doing to my testosterone levels...and what will it continue doing latter on.....
