This new formula by bpi is a very decent Pre-workout and gives you the pump and energy you want from a pre-workout. Very similar to the original 1MR without the DMAA and other additives. Overall, it is a good pre-workout to use either by itself or with a stack. The value is probably the best part of this product as it is 50 servings (1 scoop per serving) and for its price you can't get much better. Only negative I have on this product is the taste. I tried the fruit punch flavor and did not like the mixture at all. Basically, if you don't mind the taste it is definitely worth purchasing.
