I compete and i competed natural at first. You still need to manipulate the water and salt (at least that is what i was taught and did). The manipulation is about the same because you really do not want AAS in your system for competition. That is what the experts here have advised.
I am still expirementing with the whole dehydration thing and am using the advice provid d here. We will see what happens. I was looking flat for the competition because i started dehydrating like 5 days before.
