30-Second Review

Bulk by Transparent Labs is a medium-stim pre-workout. A daily driver. Bulk is 200mg of organic caffeine, 200mg of L-theanine, 8g of citrulline malate, 4g of beta-alanine, 2.5g of betaine, 1g of tyrosine, and 300mg of alpha-GPC. It is Informed Sport tested. A few reviews say the stevia flavors taste sharper and less like candy than typical pre-workouts, and it depends on the flavor.

You get 4g of beta-alanine, 300mg of alpha-GPC, and 200mg of caffeine paired with theanine. It is Informed Sport tested, and every dose is right there on the label. The tub is $49.99 for 30 servings, about $1.67 each. The limit is that 8g of citrulline malate works out to about 5.3g of actual citrulline.

Pros

You get 4g of beta-alanine, 300mg of alpha-GPC, and 200mg of caffeine paired with theanine
It is Informed Sport tested, and every dose is right there on the label

Cons

8g of citrulline malate works out to about 5.3g of actual citrulline
The scoop is still useful, but the tub looks more loaded than it is because part of that number is malate
