A single AS is not a bad way to go if you have the time and the patience. I'm on my first cycle and I chose Sus/deca/dbol. I'm pretty sure I'll have good gains but the problem is I will never know which AS gave the best gains. I also won't know the most effective dosage for my body either. But, I'm 34 and been training natural for 18 years now. I'm done being patient.
If you're young, start lite.
