Ok first of all you can mix anything any way that you want, but try to stay around 3cc or maybe 4. I have even mixed water bases with oil bases, so no big deal. BUT the best protocol would be to use everything and then do that twice per week. For instance lets say I am going to do a stack of 400 test cyp/400deca/400eq. What I would do is pull up 200,200,200 and shoot that twice per week. Better to not do say 400 of any single one by itself. Makes sense?
