Alex a natural only can get a certain amount of muscle no matter what his genetics. So you are not close to pro size, not at all. Pros are on tons of gear and have way more muscle than you have, if you dieted down most of what you see as muscle would disappear.

Bingo. Alex has no neck, plenty of blubber there. I don't see the need for sauce already big n beefy. If you have to find out research it, do 1 or 2 cycles just to find out how it works in your case, what differences it makes, Not because it's realistic to win shows. A coupla cycles isn't going to seriously impact health compared to pro intakes over years.
As far as dieting down of course some of the size will go but a more athletic look will be there instead of great measurements. Is it worth the pain of dieting and maintaining it for that more athletic, smaller look..
