Okay so your saying that your going to do steroids. Alright I'm not going to give you the lecture about how your to young.
1. Dbol isn't to be taken on its own. You need to have test with it.
2. The half life of dbol is kinda short so you don't take it all at once. In you're case, I'd recommend taking 10mgs at b'fast, lunch, and dinner.

3. You said your skinny, right? Well that's because of your diet and/or exercise. If you haven't been working out
AT LEAST 3 months (really, it should be 2 years) then don't take steroids. Here is the diet and workout link, it's pretty good for starters.

4. And now, you have the PCT (Post cycle therapy). Dbol is the best/worst steroid out there, being as it gives you the most strength/weight, but the side effects suck! I'm still learning everything about pct's, but for your case I'd get I would use clomid + nolvadex.
nolvadex (weeks 1 - 3) @ 20mg each day
clomid (week 1) @ 75mg ED
clomid (week 2 - 3) @ 25-50mg ED
If you have any questions just ask me.
Best luck - PO
