Caffeine-based products: when the main point is alertness

This category is for people who want a formula where caffeine does the heavy lifting.

The main comparison is between how much caffeine the product contains and how much caffeine is already coming from other sources. A product that is too strong for your routine is simply a poor fit, even if the label sounds energetic.

The practical choice is usually the product that makes total daily caffeine easiest to track. Small tablets, capsules, or clearly labelled servings tend to be simpler than a scoop that also includes several extra stimulants and flavour systems.

Caffeine-based products should match both the session and the hour on the clock. If you train late, drink coffee throughout the workday, or react strongly to stimulants, a lighter option or stimulant-free pre-workout may fit better.
