I kno its a proprietary blend which isnt the best thing when it comes to ph especially when its a blend of hdrol, SD, and EPi. because u dont really kno how many mg of everything ur getting and if its even dosed high enough considering out the of the 250mg tab it also has tribulus in it. but if the sd is dosed high enough im sure ull see good gains and probably be shut down too. but what else are u using for pct and is this ur first cycle?
