Hey bro, Yes, it can be hard to maintain every lb of scale weight that you gain from a test,dbol,deca cycle. Thats because the cycle is designed to induce "mass". You gain a lot of fluid from this combo, which is good for strength and recovery, but you are never meant to keep that water once you're off. EQ is another great steroid and the gains will be easier to maintain, mainly because you probably won't have gained as much fluid while on it.
Nolvadex can initally cause an upregulatation of progesterone receptors. You're better off using an AI and if you have a progesterone issue, caber.
