Our ingredients and quality standards

How to Do Vitamins.

Taste warning: PurePump is bitter. Intentionally. There's no sucralose, no artificial flavoring, nothing hiding the raw ingredients. If you want a delicious fruity beverage, this isn't it. If you want 15 active ingredients with nothing to hide behind, welcome.

We suggest less liquid, not more. Think of it like a shot. Water will be bitter; a citrusy, sour juice or a sports drink can help balance the bitterness. Use a shaker bottle, and follow the label directions.

When to take it: Take PurePump 15-30 minutes before training.

Full dose (2 scoops / 7.7 g): 200 mg of natural caffeine from coffee bean and all 15 active ingredients at full strength.

One scoop: 100 mg of caffeine. Start with one scoop to assess your tolerance.
