It's decent, but if it's so "extreme" why is there such a small amount of dynamine, choline bitartrate, and teacrine? There should be a yield of at least 100 mg of dynamine, not 30-something. There should be a yield of at least 200 mg of teacrine. There should be at least a gram of choline bitartrate. Plain yeah buddy is much better, so I recommend that people just order that.
