C4 Whey Protein Hershey's Milk Chocolate

C4 Whey Protein in Hershey's Milk Chocolate flavor is a sports nutrition supplement resulting from a strategic licensing partnership between Nutrabolt and The Hershey Company. Launched in 2024, this product combines the high-performance heritage of the C4 brand with the iconic chocolate taste synonymous with the Hershey's name.

The product is manufactured in the United States by Nutrabolt (operating legally as Woodbolt Distribution, LLC), utilizing a blend of high-quality whey proteins. The brand's origin traces back to 2002 with the launch of the Cellucor line, which eventually gave rise to the C4 flagship brand, now a leader in the global pre-workout and energy sectors.

Since December 2022, Nutrabolt has partnered with beverage giant Keurig Dr Pepper (KDP), which holds an approximately 30% equity stake in the company. As of 2026, Nutrabolt remains a privately held American company headquartered in Austin, Texas, continuing to manage it's portfolio of wellness and active nutrition brands like C4, Cellucor, and XTEND.
