Sportness Pre-Workout Booster Tropical 290 g: 150 mg caffeine per serving

This Sportness booster is dosed transparently, which is rarer in pre-workout powders than it should be. Each serving delivers 150 mg of caffeine and 100 mg of L-theanine, a pairing that is deliberate: theanine takes the edge off the jitteriness caffeine alone can produce.

The powder also supplies amino acids including L-citrulline and L-arginine, rounded out with a blend of vitamins and potassium. Pantothenic acid contributes to normal energy metabolism, and potassium contributes to normal muscle function.

One hundred and fifty milligrams of caffeine is roughly a strong double espresso. Take it too late in the day and it will still be working at bedtime, so keep training sessions well clear of the evening.
