What is Gainful Pre-Workout?
Gainful is a supplement brand with several pre-workout formulas. Its current range includes Performance, High Intensity, and Caffeine Free Pre-Workout. Choosing between them starts with the exact product name: caffeine, creatine, and several other ingredient amounts change between versions. This label-based guide uses Gainful’s manufacturer pages and Supplement Facts images checked on October 12, 2026.
Caffeine and creatine by version
- Performance: 150 mg caffeine and 3 g creatine monohydrate per approximately one-scoop serving.
- High Intensity: 200 mg caffeine and 5 g creatine monohydrate per approximately one-scoop serving.
- Caffeine Free: 3 g creatine monohydrate, with no caffeine listed in the formula.
These are distinct recipes. High Intensity also contains more leucine and L-theanine than Performance, so comparing only their caffeine totals misses part of the difference. All three manufacturer pages offer Watermelon and Strawberry Lemonade flavors.
What else is on the labels?
The current labels for all three versions list 4 g L-citrulline DL-malate 2:1 and 1.5 g beta-alanine per serving. The citrulline figure refers to the combined citrulline-malate ingredient, rather than 4 g of pure L-citrulline.
Performance and Caffeine Free each list 1 g leucine, 500 mg isoleucine, and 500 mg valine. High Intensity raises leucine to 2 g while retaining 500 mg each of isoleucine and valine. Performance supplies 250 mg L-theanine; High Intensity supplies 330 mg. The Caffeine Free label does not list L-theanine.
Flavoring ingredients include natural flavors, stevia leaf sweetener, and beet powder. Strawberry Lemonade also lists lemon fruit powder. Read the selected flavor’s complete label when checking ingredients.
Serving size and buying checks
Each current tub label states about 20 servings. Scoop weights vary: Performance is 12.7 g for Watermelon or 12.9 g for Strawberry Lemonade; High Intensity is 16.1 g or 16.6 g; Caffeine Free is 12 g or 12.3 g, respectively. An old scoop from another formula is therefore a poor measuring reference.
Gainful’s mixing instructions call for 8 oz of cold water, approximately 20 minutes before exercise. Follow the directions and warnings on the product you receive. The manufacturer identifies these supplements for healthy adults aged 18 and over and advises consulting a physician for pregnancy, nursing, medication use, or medical conditions.
For a practical comparison, check the caffeine amount you want, whether you already use creatine, the serving count, and the exact flavor label. These ingredient facts do not establish how a product will taste or perform for you.
