It comes down to this.
Gear is illegal, expensive, risky, and has health consequences.
You shouldn't use it to get gains you could get naturally, just because you're in a rush. You should use it, if you use it at all, to get supernatural gains that aren't possible naturally.
As I said in my long-winded post, I think it's actually an advantage to train naturally, because you learn how to make your body grow optimally. You learn to become more disciplined in order to keep making gains, it builds character, yadda yadda.
On a bunch of drugs, basically everything works.... to a point. It will mask flaws in your training, diet, supplement regimen, sleep patterns, etc.
You said you can bench 205 right now. I say, wait till you can bench 305 NATURALY. Use that time to learn to eat and train, to where you can get to benching 305+ naturally. Learn to use food as your main anabolic compound, along with protein and amino acid supplements.
Once you're there, if you still want to use stuff, it's up to you.
Edit: If you can't figure out how to bench 305 naturally, what will you do when the drug gains stall out at your 315 bench? Just take more drugs?
