With winstrol the uses shouldn't gain much mass,winstrol is a cutting and hardening drug. Anadrol on the other hand not the case, it is a very powerful mass gainer and you will retain lots of water I believe that's why people lose a lot after they come off cuz they shed all that water. And BTW I do not recommend anadrol or sunstroke only cycles. Always have test as base of cycle.
