30-Second Review

PEScience's original stim. The label serving is two scoops: 320mg of caffeine, 6g of L-citrulline, 2.5g of betaine, 1.5g of taurine, 200mg of L-theanine, and 250mg of Cognizin. No beta-alanine. The tub is 40 scoops, which is 20 full servings. One scoop is the half dose.

A full serving is 6g of L-citrulline, 2.5g of betaine, and 200mg of L-theanine with no tingles. 320mg of caffeine is split between anhydrous and delayed di-caffeine malate. The tub is $39.99 for 20 servings, about $2.00 each. The limit is that the tub is 40 scoops, but the doses on the label are for two scoops, so you get 20 workouts.
