30-Second Review

Nitraflex Advanced by GAT Sport is a high-stim pre-workout. The current Nitraflex. One scoop is 325mg of caffeine and 1g of Nitrosigine. Citrulline sits in a 3.7g blend with that Nitrosigine, and beta-alanine sits in a 2.6g energy blend with tyrosine, DMAE, and rauwolfia, so neither pump dose is written out. No creatine.

325mg of caffeine and 1g of Nitrosigine are written out. The tub is $29.99 for 30 servings, about $1.00 each. The limit is that citrulline and beta-alanine share blends, so those doses are not written out.
