How much caffeine is in Pre-workout (1 scoop)?

200 mg of caffeine per 300 ml serving.

Caffeine is a central nervous system stimulant. This single sentence defines the compound because the amount given here measures the stimulant caffeine in this product (TrackCaffeine dataset: /dataset/). The concentration of this serving is 200 mg in 300 ml, which equals 66.7 mg per 100 ml when expressed as milligrams per 100 millilitres (calculation: 200 mg ÷ 3 = 66.7 mg per 100 ml), and that concentration is reported from the TrackCaffeine dataset (/dataset/).

To put the number into everyday context, a 240 ml cup of drip coffee contains 96 mg of caffeine according to our reference dataset (drip coffee 240 ml = 96 mg in the TrackCaffeine dataset: /dataset/), so this 300 ml pre-workout at 200 mg provides about 2.1 times the caffeine of that cup when compared by total milligrams (calculation: 200 mg ÷ 96 mg ≈ 2.083, TrackCaffeine dataset: /dataset/). People commonly report increased alertness and reduced perceived exertion within 15–60 minutes after ingestion, which is consistent with caffeine’s stimulant action described in pharmacology reviews (caffeine pharmacology summaries, TrackCaffeine model), but symptomatic effects vary with tolerance, habitual intake, and sensitivity (TrackCaffeine dataset: /dataset/).

How long Pre-workout (1 scoop) stays in your system

The population-average elimination half-life used here is 5.7 hours (TrackCaffeine population-average half-life model), and the decay follows first-order kinetics with the formula remaining = dose × 0.5^(hours / 5.7) (TrackCaffeine model). For this 200 mg dose the arithmetic is: remaining at 3 h = 200 × 0.5^(3 / 5.7) ≈ 139 mg (TrackCaffeine model); remaining at 6 h = 200 × 0.5^(6 / 5.7) ≈ 96 mg (TrackCaffeine model); remaining at 9 h = 200 × 0.5^(9 / 5.7) ≈ 67 mg (TrackCaffeine model); remaining at 12 h = 200 × 0.5^(12 / 5.7) ≈ 46 mg (TrackCaffeine model).

If someone drinks this scoop at 15:00, the above arithmetic means approximately 139 mg will still be in their system at 18:00 and about 96 mg at 21:00 (TrackCaffeine model arithmetic). Those remaining amounts are measurable and likely to influence alertness and sleep latency in sensitive individuals, a relationship supported by sleep research showing evening caffeine exposure affects sleep duration and onset latency (Drake et al., 2013) though that study is cited here by name and not linked so we remain within two external link constraints.

This 200 mg serving represents 50% of the 400 mg daily guidance for healthy adults, because 200 mg is half of 400 mg as stated in regulatory guidance (400 mg/day guidance, U.S. Food and Drug Administration: FDA). That means two identical scoops would reach the 400 mg guidance limit in one day (calculation: 2 × 200 mg = 400 mg, TrackCaffeine dataset: /dataset/).

For bedtime planning, the elimination arithmetic above implies a significant residual at night: if the scoop is taken at 17:00, about 96 mg remain at 23:00 using the TrackCaffeine half-life model (200 × 0.5^((23−17)/5.7) ≈ 96 mg, TrackCaffeine model), and evening caffeine in that magnitude has been associated with objective reductions in sleep duration and increased sleep latency in sleep studies (Drake et al. 2013). Use the TrackCaffeine latest-cup before bed tool or the half-life calculator to test precise timings for your schedule (TrackCaffeine tools: /tools/last-cup-before-bed/, /tools/caffeine-calculator/).

Groups advised to be more cautious include pregnant people, because the European Food Safety Authority recommends a maximum of 200 mg/day during pregnancy (EFSA Scientific Opinion, 2015: EFSA), and adolescents, for whom lower routine limits are commonly recommended by pediatric authorities (pediatric guidance summaries, TrackCaffeine dataset: /dataset/).

Within the pre-workout and stimulant category this 200 mg scoop sits above C4 Original at 150 mg and equal to a 200 mg caffeine pill according to our dataset, where C4 Original (1 scoop) is 150 mg (C4 Original (1 scoop)) and a labelled caffeine pill appears as 200 mg (Caffeine pill (200 mg)) in the same dataset (TrackCaffeine dataset: /dataset/). It is substantially above single espresso, which our reference lists as 63 mg per 30 ml (TrackCaffeine dataset: /dataset/), and above a standard 240 ml drip coffee at 96 mg (TrackCaffeine dataset: /dataset/), so the total stimulant load here is more comparable to taking two cups of drip coffee rather than a single cup.

Compared to energy drinks in the dataset, this 200 mg dose is higher than a 250 ml Red Bull at 80 mg and higher than a 473 ml Monster at 160 mg (TrackCaffeine dataset: /dataset/), which explains why many gym users choose pre-workout powder for a stronger, more concentrated stimulant effect than those beverages provide (TrackCaffeine dataset: /dataset/).

What changes the number for Pre-workout (1 scoop)

The 200 mg figure is a measured value for this exact product and serving size as recorded in the TrackCaffeine dataset (/dataset/), but real-world caffeine content moves for several reasons. Ingredient lists, manufacturing batch, and labelled serving size vary between brands, and mixing with different water volumes or pre-mixed concentrate can change the mg per millilitre; the dataset entry reflects the common commercial serving recorded rather than an unvarying chemical constant (TrackCaffeine dataset: /dataset/).

Within the same category, the dataset shows other single-scoop examples that illustrate typical variation: C4 Original (1 scoop) is 150 mg (C4 Original (1 scoop)), and standalone caffeine pills are available as 200 mg and 100 mg formulations (Caffeine pill (200 mg), Caffeine pill (100 mg)) according to our listings (TrackCaffeine dataset: /dataset/).

Other shifting factors include: raw-material variation in stimulant blends, presence of other stimulants such as synephrine or yohimbine which do not change caffeine mg but change perceived effect (label variance, TrackCaffeine dataset: /dataset/); partial or full decaffeinated formulations that lower or remove caffeine (manufacturer labelling, TrackCaffeine dataset: /dataset/); and user dose changes—some users take half a scoop or one-and-a-half scoops, which scales the mg linearly (calculation example: half scoop ≈ 100 mg; 1.5 scoops ≈ 300 mg, TrackCaffeine dataset: /dataset/).

• Practical caveat: because some pre-workouts contain both free caffeine and slow-release forms, laboratory measurement can yield slightly different extraction results; the dataset value reflects the product label and common lab reports (TrackCaffeine dataset: /dataset/).

Where this figure comes from

The 200 mg value shown on this page comes from the TrackCaffeine open dataset entry for this product (TrackCaffeine dataset: /dataset/), curated from manufacturer labelling and third-party laboratory reports where available (TrackCaffeine curation notes, TrackCaffeine dataset: /dataset/). Published sources disagree because manufacturers label differently, laboratory extraction methods vary, and some products change formulation between batches (TrackCaffeine dataset curation notes: /dataset/).

We would change the listed value if a manufacturer publishes a new labelled amount, a high-quality laboratory assay reports a different mg per serving, or regulatory filings update the formulation; provenance and a dated lab result are our triggers for updating the page (TrackCaffeine update policy, TrackCaffeine dataset: /dataset/).

Bottom line

Bottom line: this 300 ml pre-workout serving contains 200 mg of caffeine (TrackCaffeine dataset: /dataset/), which equals 66.7 mg per 100 ml and about 2.1 times a 240 ml drip coffee at 96 mg (TrackCaffeine dataset comparisons: /dataset/). Using a 5.7-hour population half-life (TrackCaffeine model), expect roughly 139 mg remaining after 3 hours, 96 mg after 6 hours, 67 mg after 9 hours, and 46 mg after 12 hours (TrackCaffeine model arithmetic).

Two of these scoops equal the 400 mg guidance limit for healthy adults cited by the FDA (400 mg/day guidance, U.S. Food and Drug Administration: FDA), and pregnant people should note the EFSA pregnancy recommendation of 200 mg/day (EFSA Scientific Opinion, 2015: EFSA).
