Caffeine has more peer-reviewed performance research than every other supplement combined. Strength, power output, endurance, pain tolerance, reaction time, focus — all measurably improved at the right dose, in the right window, in non-tolerant individuals. It is also one of the most badly used substances in training: too much, too late in the day, daily without rotation, often combined with pre-workout 'proprietary blends' that hide the actual dose. Used correctly, it adds 2-4% to your top-set output. Used badly, it wrecks your sleep and your sleep wrecks everything else.
Effective dose (by bodyweight)
The performance dose for resistance training is 3-6 mg per kg of bodyweight, taken 45-60 minutes before training. For a 70 kg lifter, that is 210-420 mg. For an 85 kg lifter, 255-510 mg. Below 3 mg/kg the effect is inconsistent; above 6 mg/kg returns diminish sharply and side effects (jitter, blood pressure, GI distress) rise.
Most pre-workout supplements contain 200-350 mg of caffeine per serving — sufficient for smaller lifters, sub-dosed for larger ones. A regular cup of coffee contains 80-130 mg (varies widely by brewing method). One espresso shot: 60-80 mg. One can of energy drink: typically 80-160 mg.
Timing — the half-life problem
Caffeine's plasma half-life in adults averages 5-6 hours. A 300 mg dose at 6 pm leaves 150 mg active at midnight and 75 mg at 6 am. This is the single biggest reason lifters chronically under-sleep without knowing why.
Practical rule: no caffeine within 8-10 hours of intended bedtime. If you sleep at 11 pm, the last dose is 1-3 pm. Evening training sessions are the most caffeine-restrictive — a 7 pm gym session benefits from caffeine in theory, but the cost in sleep quality typically exceeds the performance gain. Most evidence-based athletes train evenings without caffeine, training mornings or early afternoons with it.
Tolerance and how to manage it
Daily caffeine use causes adenosine receptor upregulation — the body compensates for the blockade, and the same dose produces diminishing performance benefit within 7-14 days. After 30 days of daily 300 mg use, the performance benefit may be entirely absent (Bell & McLellan, 2002).
Three workable strategies: (1) Use caffeine only on hard training days (2-3x/week) — most effective for performance gains. (2) Cycle on/off in 6-8 week blocks — heavy use during peaking phases, complete abstinence between. (3) Lower-dose habitual use (100-200 mg/day) with no expectation of performance benefit — appropriate if you drink coffee for enjoyment but want to keep the option of higher doses producing genuine effect later.
What to skip
Proprietary blends. Any pre-workout that lists 'Energy Matrix: 1.5g' without separating the doses is hiding the caffeine content. Buy products that label caffeine in mg explicitly.
Caffeine + 'fat-burning stack' combinations. Synephrine, yohimbine, and similar compounds combined with caffeine produce cardiovascular load disproportionate to the modest fat-loss effect. Not worth the risk.
Pre-workouts with caffeine 'and other stimulants' totalling 400+ mg. The effective dose for resistance training caps around 6 mg/kg. More is not more — it is just more side effects.

Key takeaways
Effective dose: 3-6 mg per kg bodyweight, 45-60 minutes pre-training.
Half-life is 5-6 hours — no caffeine within 8-10 hours of bedtime.
Daily use upregulates adenosine receptors; tolerance reduces performance benefit within 7-14 days.
Best strategy: use only on hard training days (2-3x per week) for genuine performance gains.
Avoid proprietary blends, stimulant stacks, and products over 400 mg per serving.
