Caffeine
Caffeine is a stimulant that reliably improves alertness and exercise performance at moderate pre-workout doses.

Evidence summary
Research confidence: high
ISSN recommends 3-6 mg/kg ~60 min pre-exercise; 200-400 mg spans typical 65-120 kg adults. Caffeine counts toward the Dose score, earning full credit at 200 mg with no extra credit above it, and its amount also sets the stim-tier badge; it's excluded only from the Transparency score, which covers other disclosed actives.
