50% water and glycogen would be my guess. even with anabolics the most muscle tissue ur body can synthesize per week would be 2.5lbs and thats in the most ideal situation. so 6 weeks gaining 30 lbs wouldnt be all muscle. in a mesomorphic person with the best diet and perfect training 6 weeks could gain 15 lbs of LBM. So Dbol is going to put on a lot of weight but ur not gonna keep more than half unless u run test with it and I wouldnt want to run dbol without test anyways. If ur gonna use Dbol then use it to kickstart a test cycle or ur selling urself short
