Is C4 / Cellucor third-party tested?

Yes. C4 / Cellucor holds 3 verified third-party certifications: Health Canada Licensed, Nsf Certified For Sport, Fda Gmp Inspections. Third-party testing means an independent laboratory — not the supplement company itself — has verified the product's contents, purity, and/or manufacturing practices. This is one of the strongest indicators of supplement quality because it removes the conflict of interest inherent in self-testing. Not all certifications are equal: NSF International and USP are considered the gold standard, while GMP certification indicates proper manufacturing practices.

Based on GoodSupp's quality analysis, the highest-rated C4 / Cellucor supplements are: COR-Performance® Creatine, Unflavored, 12.69 oz (360 g) (score: 100/100); COR-Performance® Creatine, Blue Raspberry, 11.1 oz (315 g) (score: 100/100); COR-Performance® Creatine, Jolly Rancher, Cherry, 11.3 oz (321 g) (score: 96/100). These scores are calculated from ingredient quality, dosage adequacy, bioavailability, label transparency, and inactive ingredient safety. Scores can vary significantly across a brand's product line — a high brand trust score doesn't guarantee every individual product is top-quality.
