You should use at least 200mgs of testosterone/week with ostarine 25mgs/ed and nutrobal 25mgs/ed (sarms1.com). Add cardrine GW for endurance/cardio @ 20mgs/ed.

At your age, a simple testosteron cycle with cardarine/ostarine/andarine mix will yield the best results.

Dbol is not good for bikers but it's alright if you want to get bigger. Add some Anabolicum LGD to the mix.
30mgs Dbol/ED
20mgs Cardarine/ED

I would do a 4 week pct, then move into the SARMS triple stack with lowered Osta/Andarine dose 12.5mgs for first 2 weeks then shift up. Like a PCT->bridge pyramid.
If you want to bulk up, you can do a short run like this.
Week 1-8
Dianabol 50mgs/ed
Osta mk2866 25mgs/ed (sarms1)
Andarine 25mgs/ed (s1)
aromasin 10mgs/eod
N2guard 7caps/ed (liver/kidney support)

Before you think about building more mass or using steroids. I suggest you cut down to 10% bodyfat with SARMS, keep your base building then one day jump back on a stack.
