the lad wants help...dont you think he deserves advice ? he maybe young...but he will do it soooo...i think the best way is to atleast make sure he knoes exactly what hes putting in his body, would you rather him run a cycle and not know what hes doing at all or do a cycle and have abit of knowledge on pcts ect..to make it as safe as its going to get for an 18yr old?
