30-Second Review

Optimum Nutrition's high-stim. The serving is 3 scoops, 18g: 300mg of caffeine, 6g of micronized L-citrulline, 3.5g of beta-alanine, and 900mg of Neumentix spearmint extract. The electrolyte blend is 890mg and is not split out. No creatine. Do not take more than one serving a day.

Three scoops write out 6g of citrulline and 3.5g of beta-alanine, and the tub is 20 of those servings. The tub is $24.99 for 20 servings, about $1.25 each. The limit is that there is no creatine, and 300mg of caffeine is a lot if you are new to pre-workout.
