Sure, use clen. Clen is anti-catabolic so no real need to worry about burning muscle for fuel. Dose as you see fit, you'll start low, say 20 or 40mcg to start, then build up to your tolerance level within the first week. Run 2 weeks, then stop for 2 weeks; repeat. You can buy ketotifen which would allow you to run clen non-stop. 1ml ketotifen daily.
