Hot Blood is a Scitec Nutrition pre-workout product line. Identify the version before comparing caffeine or ingredients: current Infinity powder, Infinity No-Stim, older Hardcore powder and Hardcore Shot have different labels.
Hot Blood Infinity: read the daily amount
The current official EU listing gives these quantities for a 25 g daily amount, divided into two 12.5 g portions:
- 300 mg total caffeine
- 8 g L-citrulline and 2.974 g AAKG, providing 2 g L-arginine
- 3.411 g creatine monohydrate, providing 3 g creatine
- 1.4 g beta-alanine and 1 g L-tyrosine
- 250 mg Cognizin citicoline
Therefore, one 12.5 g portion supplies 150 mg caffeine, and a 350 g tub contains fourteen complete 25 g daily amounts. A listing advertising 28 portions does not mean 28 full daily amounts.
The other versions are not interchangeable
- Infinity No-Stim: The current 350 g product has its own 25 g serving and no caffeine entry. Scitec lists 8 g L-citrulline, 3.411 g creatine monohydrate and 250 mg citicoline among its ingredients. It also omits the caffeinated Infinity’s green tea entry.
- Hardcore powder: The Scitec Malaysia listing describes the earlier formula with 300 mg caffeine and 1.2 g L-citrulline per 25 g daily amount. Those numbers should not replace Infinity’s panel.
- Hardcore Shot: The official 60 ml bottle listing gives 400 mg caffeine for the full bottle, plus 3 g beta-alanine. A shot is not a liquid equivalent of one powder scoop.
Directions deserve the same attention as ingredients
Infinity’s EU instructions split the prepared drink between at least four hours before training and during training. They also say not to take it on an empty stomach or with other green-tea products that day. Check the directions on your regional package instead of applying a generic 20-minute pre-workout rule.
Caffeine from all drinks and supplements adds up. FDA’s caffeine guidance emphasizes individual sensitivity; a familiar product name cannot establish that a particular serving suits you. No-stim labeling also does not replace the full ingredient and warning review.
When comparing value, calculate the cost of the exact daily amount you intend to evaluate, then compare caffeine and ingredient forms. This is a documented product-line guide, not a taste test or a promise of greater strength, heat or fat loss.
