sofa george is dead on with his answer. i've tried them alone and together, and there is great synergy....forget all that bill roberts type 1 crap. Eq can make your muscles somewhat tight, so you really want to run something to hold a little water with it (unless this is pre-contest). eq/anadrol is good, and so is eq/deca. eq also takes some of the deca bloat off. i actually think it works just as well as winstrol for this purpose. eq/deca actually gave my buddy the same results as his previous deca/winstrol cycle. i personally think eq is alot more androgenic than deca or winstrol. i get real aggressive and my hair falls out on it. also since deca increases insulin sensitivity and eq increases igf1, there is some scientific backing to their synergy. all i know is that it does work, and is a good stack if for some reason your body is screwy like mine and can't tolerate exogenous test well.
