Are you fuckin kidding me he is 16. You obviously have no clue about AAS or the human body so stay here at eroids and research research research before you give advice that will put a kid in his grave long before his time.

im hoping your "friend" isnt you. as far as side effects you should probably be fine. but the thing is it will take your hormonal system off of its homeostatic axis. there fore you'll need something to bring it back, which is your pct (post cycle therapy). but those are what will probably give you what you dont want. some my cause aromatization which is the conversion to estrogen, which could give you gyno (bitch tits) and or stunt your growth while adding more fat or pack on some water weight, which will hide all the toning youve gotten from your anavar. now you can take an anti e, but there has been some skepticism as to whether that stunts growth or not due to it binding to estrogen receptors, there fore some what acting as estrogen on growth plates. most of the teen guys who consider hopping on roids arent as dedicated as they should be. i know everyones tired of hearing the same shit, but i know its possible. you can most definitly make tremendous gains naturally. just eat like a fucking race horse, sleep like a baby and train like a beast. good luck bro, hopefully my post helped out.
