IMO this is the best pre-workout supplement I've used compared to jack3d, superpump, NO explode, and black powder. It contains a relatively large amount of protein which other pre-workout supps lack. Inter-workout protein supplementation has been shown to increase workout benefits in studies when compared to no inter-workout protein supp. It also has less sugar than other pre-workout supplements and I think the amount of caffeine is perfect to energize you without giving the jitters.
