GAT Sport Nitraflex
GAT Sport Nitraflex is a pre-workout with 325 mg caffeine per serving. StimIndex grades it F tier (12.7/100, methodology v2.10.1). Third-party testing: none on file. It isn't clinically dosed, so there's no fair price per clinically dosed serving (lowest price $29.99, checked Oct 2, 2026).
The label math says this one is mostly hope.
