I find using more compounds at more reasonable doses reaps more gains than say a high dose of one compound. Only have one cycle with a higher dose and more than a few with multiple. I'd say if you were to run Dbol/Test/deca run it as follows. Btw, wasn't saying you were too young just stating the obvious. We're all lookin out for you Test, we know you have basic knowledge of different compounds.

Dbol: 30-50mg/day wks 1-4(or 6)
Test: 750mg/wk 1-12 (since last cycle you did 600)
Deca: 400mg/wk 1-11
This would put you a bit over a gram total but still be resonable dosages at your level IMO.

This stack should do you well building Mass if that is what you are aiming for. Simple, yet very effective.
