What the evidence says

Caffeine is effective and safe in moderation; the risk comes from unknowingly stacking multiple sources.

Typical dose & timing

Dose: Keep total daily caffeine under ~400 mg for most healthy adults; less if sensitive.

Timing: Avoid stimulants within ~8 hours of sleep.

Role in a stack

A safety principle, not a product.

Redundancy check: Count every caffeine source together.

Cautions & safety

Pre-workout + coffee + energy drinks + fat burners can stack dangerously. Theacrine/dynamine add to the load.

Tachycardia/anxiety/insomnia from over-stacking. Educational only — not medical advice.
