I have cycled at 25%+ and got down to 9% on a 16 week cycle. Came out looking jacked as hell too. It took a strict diet and workout routine. Very strict. Steroids don't do the work for you.
To be honest, I was probably a lot higher than 25%. I was 242lbs at 6'1. I dropped down to 189lbs, and maintained it around 195lbs. I looked 225+ though.
