Frequently Asked Questions

Is Cellucor legit?

Cellucor earns a Trust Score of 52/100 (C Tier). C4 pre-workout is a real and widely used product, but some ingredient amounts are hidden in proprietary blends. Quality for protein and creatine products is average at above-market pricing.

Is C4 pre-workout safe?

C4 Original is generally considered safe at recommended doses for healthy adults. It contains caffeine, beta-alanine, and creatine nitrate. The partial use of proprietary blends limits transparency on exact dosages of some ingredients.

Is Cellucor NSF certified?

No. Cellucor does not hold NSF Certified for Sport status. Athletes subject to drug testing should choose NSF-certified alternatives such as Thorne, Klean Athlete, or Garden of Life.
