Short answer: A keto pre-workout should make it easy to evaluate what you are taking. Start with the serving size, caffeine amount, full ingredient disclosure, and any independent certification. A phrase such as "keto friendly" is not enough on its own. Read the Supplement Facts panel and ingredient list, then decide whether the product fits your dietary plan and stimulant tolerance.
PurePump® is an unflavored, Keto Certified pre-workout with 15 disclosed active ingredients. A full 2-scoop serving is 7.7g and lists 2,000mg beta-alanine, 2,000mg L-citrulline, and 200mg caffeine from coffee bean; one scoop contains 100mg caffeine. It contains no artificial flavors or sweeteners. The current certificate record is dated September 8, 2026, for lot 797797 and describes a testing menu of more than 450 drugs. Match a certificate to the lot on the product you receive before treating it as batch-specific evidence.
A keto pre-workout label checklist
Use this checklist before you buy a pre-workout for a ketogenic diet.
1. Look for complete ingredient disclosure
You should be able to see the amount of each dietary ingredient per serving. A proprietary blend can list a combined total for several ingredients rather than each individual amount. That makes it harder to compare a formula with the research or another product.
The FDA requires a proprietary blend to identify the blend and its total weight, with the other dietary ingredients listed in descending order by weight. It does not require an individual amount for every ingredient in that blend. Learn how proprietary blends work →
2. Check the serving size and caffeine amount
Do not compare tubs by scoop count alone. Check the recommended serving, the number of servings per container, and the amount of caffeine in the serving you plan to take.
PurePump has 60 scoops, or 30 full 2-scoop servings. Its label provides 100mg caffeine per scoop and 200mg per 2-scoop serving. Follow the label directions. If you have a health condition, take medication, are pregnant or nursing, or have questions about caffeine, consult a qualified clinician before using a supplement.
3. Check the nutrition and ingredient lists against your own plan
Review the complete label rather than relying on a front-label claim. People following keto use different carbohydrate targets and food plans, so a product choice should fit the plan you actually follow.
For example, a pre-workout can be sugar-free and still use ingredients you prefer to avoid. Similarly, a non-nutritive sweetener does not create a universal, predictable response for every person. Keep the decision grounded in the full label and your own dietary approach.
4. Distinguish certification from a marketing phrase
Independent certifications give you another record to review. They do not replace reading the label, but they are more useful than an unsupported front-label phrase.
For an athlete who competes in drug-tested sport, third-party banned-substance testing can be especially relevant. A lot-specific certificate is useful only when its lot matches the product in hand. View the September 2026 PurePump Unflavored lot-797797 certificate →

A note on caffeine source
PurePump's caffeine comes from coffee bean. That identifies the source; it does not change the amount of caffeine in the serving or replace normal caffeine precautions. The relevant numbers are 100mg for one scoop and 200mg for a full 2-scoop serving.
A note on creatine
PurePump contains 1,000mg creatine monohydrate per full serving. That is not a replacement for a separate daily creatine routine if you are aiming for the amounts commonly used in creatine research. The NIH Office of Dietary Supplements notes that studies often use 3 to 5 grams per day after an optional loading phase. Read the NIH overview of exercise supplements →
How to use an unflavored pre-workout
PurePump has no artificial flavors or sweeteners. That means it tastes bitter on its own. This is intentional: the formula does not use flavoring or sweetening systems to mask the ingredients.
Use one to two scoops with a beverage you already use 15 to 30 minutes before training, according to the label. Because the powder is bitter, use less liquid, not more—think of it like a shot. A citrusy, sour juice or a sports drink can help balance the bitterness. If you are new to the product or prefer a lower caffeine amount, start with one scoop.
