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.
