Frequently Asked Questions
Is C4 / Cellucor a trustworthy supplement brand?

C4 / Cellucor receives a brand trust score of 79/100 in GoodSupp's independent analysis. The company was founded in 2002 and is headquartered in Austin, Texas, USA. Our research did not find independently verified third-party certifications for this brand. While this doesn't mean their products are low quality, third-party testing is considered a strong indicator of commitment to quality assurance. Note: C4 / Cellucor has 6 historical regulatory incidents on record. These are factored into the overall trust score and are detailed in the violation history section above.

Is C4 / Cellucor third-party tested?

GoodSupp's research did not find verified third-party testing certifications for C4 / Cellucor. Third-party testing by organizations like NSF International, USP, or Informed Sport is considered one of the strongest indicators of supplement quality. Without it, consumers must rely more heavily on the brand's own quality claims. This doesn't necessarily mean C4 / Cellucor's products are low quality, but it does mean there's less independent verification of their claims.

What are the best C4 / Cellucor supplements?

Based on GoodSupp's quality analysis, the highest-rated C4 / Cellucor supplements are: COR-Performance® Creatine, Unflavored (score: 100/100); COR-Performance® Creatine, Blue Raspberry (score: 100/100); COR-Performance® Creatine Jolly Rancher Cherry (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.

Where is C4 / Cellucor located?

C4 / Cellucor is headquartered in Austin, Texas, USA. The company was founded in 2002. They currently offer 60 products in their supplement lineup. Their official website is cellucor.com. Manufacturing location may differ from corporate headquarters — look for GMP certification to verify manufacturing quality standards.
