Superdrol is, first of all, banned now. So, it's gotta be some kind of clone. Just like Beastdrol was a clone of Superdrol when it became banned, and then they banned Beastdrol (I know, stupid name).
Very hard on liver. Can not use for over 4 weeks in a row. It's because of this that pro-hormones/designer steroids may put some muscle on you, but you can never keep it with 4-6 week cycles.
And, most importantly, yes, you are too young. You need some muscle to build on. Work out hard for a good 4 more years. If you need PH's/DS's for a crutch now, you'll never be able to keep with working out if you aren't on the "juice". And then, when you are ready... you'll have met enough people to get a hook up on something that WILL add keepable size to you. Some real Test, Tren, Winny, etc. (Not that someone should do anything other than just test @ 500mg/week as a newbie).
