As ive said now for a decade, higher concentrations dont mean you just get the most for your money because the "most" is not defined as what everyone thinks.. you may get more total test mg for mg out of it, but what exactly is the point when you are absolutely miserable from the the pain that goes with it? take it as a lesson learned and stick with normal concentration levels where you see 200-250 per cc or with propionate, 100 per cc... equipoise is one of the very few you can get away with higher concentrations and not get pip but its generally best to stick with the standard type concentration levels...
