Transparent Labels, Innovative Ingredients

Every product built on the Project Clear Evolution platform is founded on three core pillars:

  • Clean: No artificial dyes. No artificial flavors.
  • Clear: Fully transparent labels. No proprietary blends.
  • Evolved: Innovative ingredients. Enhanced formulas.

As a Clean, Clear, and Evolved pre-workout powerhouse, C4® Ultimate is free from artificial flavors and dyes, made with a fully disclosed formula, and upgraded with cutting-edge performance ingredients like NitraMax (NO3-C)™ Citrulline Nitrate and a double dose of pump-boosting nitrates.*

FEATURING NITRAMAX (NO3-C™)

Created by bonding citrulline with patented nitrates, NitraMax (NO3-C) is an advanced compound that delivers dual-pathway nitric oxide (NO) support. Unlike citrulline or citrulline malate, which work through a single mechanism, NitraMax™ supports two mechanisms of NO creation, the arginine pathway (eNOS) and the nitrate-nitrite conversion system, to help promote the ultimate pump.*
