5/5
This stuff is top notch all the way. Full doses of all ingredients and no proprietary blends (other than their creatine blend). It's the best non-stim containing preworkout out on the market.
Flavor- It's a citrus-y orangeish kinda flavor which goes well with the large amount of B-vitamins. I have no trouble chugging it down or sipping on it during training.
Stacks very well with carnitines like PLCAR, Alcar , and LCLT
It won't give you a jolt of energy like most stim-based preworkouts but it's effects on endurance and strength were definitely what kept me buying. I've used it many time when I cycle off stims or simply don't want a stimulant "buzz" in the gym.
