Updated September 2026. This comparison covers C4 Original, not C4 Sport. Formulas, flavors, and prices can change, so use the linked manufacturer pages and current Supplement Facts panels before you buy.
Short answer: PurePump and C4 Original now list the same 200mg caffeine amount per full serving. The bigger choice is format and what you want to see on the label. PurePump is an unflavored, 2-scoop formula with 15 individually disclosed active ingredients, no artificial flavors or sweeteners, and BSCG Certified Drug Free testing. C4 Original is a flavored, 1-scoop formula with 30 servings and a different ingredient approach.
Neither option suits everyone. If flavor and a single-scoop format matter most, C4 Original may be the better fit. If you want no artificial flavors or sweeteners, complete ingredient disclosure, and batch-level banned-substance testing, PurePump is built for those priorities.

The material differences
Caffeine amount is no longer the deciding factor
Both products list 200mg caffeine for a full serving. PurePump states 100mg per scoop and 200mg per 2-scoop serving. C4 Original's current product page states 200mg per serving.
PurePump's caffeine comes from coffee bean. That identifies the source; it does not make a special performance, stomach, or keto claim. Choose a serving that fits the directions and your own caffeine tolerance.
Both products use CarnoSyn® beta-alanine
PurePump lists 2,000mg CarnoSyn® beta-alanine per 2-scoop serving. Cellucor currently lists 2g CarnoSyn® beta-alanine for C4 Original. This is a shared feature, not a reason to claim that either product automatically wins the comparison.
PurePump prioritizes a fully disclosed, unflavored formula
PurePump lists 15 active ingredients and an amount for each one. Its ingredient panel includes 2,000mg L-citrulline, 1,000mg creatine monohydrate, 500mg L-arginine, 500mg L-carnitine L-tartrate, 1,000mg total BCAAs, and the listed vitamins. It contains no artificial flavors or sweeteners, colors, maltodextrin, silicon dioxide, magnesium stearate, or proprietary blends.
That choice has a tradeoff: PurePump is intentionally bitter. It does not try to taste like a flavored drink. If that tradeoff does not work for you, a flavored product can be the better practical choice.
C4 Original prioritizes a flavored, one-scoop experience
Cellucor's current C4 Original page presents a 1-scoop, 30-serving product with multiple flavor options. It also describes CarnoSyn® beta-alanine, caffeine, PeptiPump®, and Huperzine as current product features.
That makes C4 Original a different product choice, not an inferior one. Review the exact flavor and current Supplement Facts panel before comparing ingredients or price. Those details can change across product updates.
C4 Original is not C4 Sport
Searchers often compare C4 Original and C4 Sport, but they are separate products. Cellucor currently lists 200mg caffeine for both. Its C4 Sport page also states that Sport is NSF Certified for Sport® and has a distinct hydration-oriented feature set.
This page compares PurePump with C4 Original only. Do not use a certification or ingredient claim from C4 Sport as evidence about C4 Original. If drug-tested sport is a deciding factor, review the certification on the exact product you plan to buy.

Price deserves a live check
Price, subscription offers, and retailer pricing change. PurePump is $42.95 for 30 full servings at the time of this update. For C4 Original, use Cellucor's current product page or the retailer you plan to use. Compare the current price, serving count, and the formula you actually want—not a stale price table.
