"HIV drugs" are typically just anti viral drugs that keep the virus from multiplying or at least slow it down although patients need to rotate drugs regularly. GH is just so they can maintain muscle and body wait so they don`t waste away.
Taking an anti-viral will NOT protect you from a drunken night having sex with a hooker that has HIV either. Bag it up... then you`ll only get a rash, bumps or something on the outside
