I don't think much, if any, was muscle loss... I took the DNP with clomid post cycle and my biceps measured roughly the same from the day i started clomid and about 2 weeks after i stopped the DNP... So the measurements, of at least my biceps, say none of it was muscle loss..
My diet was about maintenance level calories, 1.5g per pound of bodyweight, fairly low fat (about 40g day) and i basically ate all the carbs i could find - about 5-6 apples/day, oatmeal, and i took a glycerol supplement (glycerol fuel by twinlabs) 3 times daily.
