30-Second Review

AlphaBomb by Cellucor C4 is a high-stim pre-workout. C4's highest-stim tub. One scoop is a 336mg caffeine complex of caffeine anhydrous, liposomal caffeine, and Deura9 d9-caffeine, plus 8g of beta-alanine and 8g of VELOX, which splits into 4g of citrulline and 4g of arginine. It also has 1.5mg of rauwolfia. Cellucor says not to take more than one serving a day.

The caffeine, the 8g of beta-alanine, and the 4g of citrulline are all written out. One scoop is the full serving, so you are not doubling it. The tub is $39.99 for 20 servings, about $2.00 each. The limit is that 8g of beta-alanine is past a comfortable daily dose, and 1.5mg of rauwolfia sits on top of 336mg of caffeine.

Pros

The caffeine, the 8g of beta-alanine, and the 4g of citrulline are all written out
One scoop is the full serving, so you are not doubling it

Cons

8g of beta-alanine is past a comfortable daily dose, and 1.5mg of rauwolfia sits on top of 336mg of caffeine
4g of citrulline is a light pump dose, so this blend will not fill you up the way a 6g or 8g formula does
