Of these two options, which one is better for building muscle: taking 300 mg of testosterone per week or taking 200 mg of testosterone per week along with 20 mg of dianabol daily?
Do the dbol and test for your first 2 or 3 weeks while your testosterone levels build up. Then stop taking the dbol. It is best for jump starting your cycle, but it is very liver toxic. So you don't want to stay on it for a long time.
I think it really depends on your goals and how your body reacts. Some guys swear one is stronger, but stacking properly and sticking to a good diet makes all the difference. I've seen better gains when focusing on my nutrition and training rather than just relying on the compound itself. If you're looking for a reliable source, steroids-usa.org has been solid for me.
