30-Second Review

GNC's store-brand daily pre. One scoop is 160mg of caffeine from green tea extract, 200mg of L-theanine, 3g of L-citrulline, 2.5g of BetaPower betaine, 1.6g of CarnoSyn beta-alanine, and 805mg of electrolytes. Nothing is tucked into a blend. There is no creatine.

One scoop prints 160mg of caffeine from green tea, 200mg of L-theanine, and every other dose. The tub is Informed Choice tested. The tub is $24.99 for 30 servings, about $0.83 each. The limit is that 3g of citrulline and 1.6g of beta-alanine are about half of a full dose, and there is no creatine.
