Professional athlete running back Saquon Barkley has joined forces with Nutrabolt as the brand’s newest athlete partner, as announced by Nutrabolt on May 28, 2025.[1] The partnership is heating up for the new season, and highlights C4 Sport’s NSF Certified for Sport designation, which ensures the products meet rigorous testing standards for competitive athletes.
NFL superstar Saquon Barkley teams up with C4 Sport! The NSF Certified for Sport pre-workout ensures clean, tested supplements perfect for competitive athletes. Limited-time bundle available Sept 3-14 with 26% off + $1,000 contest running!
Barkley, who rushed for over 2,000 yards in the 2024 season, has been using C4 products for years according to the announcement. The partnership will include marketing campaigns, social media content, and retail activations featuring the athlete.
What Makes C4 Sport Stand Out for Athletes
The big story here is C4’s commitment to providing clean, tested supplements that athletes at all levels can trust, specifically with the C4 Sport line. The NSF Certified for Sport designation means every batch undergoes independent testing to verify it’s free from substances banned by major athletic organizations including WADA (World Anti-Doping Agency).
Limited-Time Bundle and Contest
From September 3-14, C4 is offering a special bundle with 26% off that includes:
- A limited-edition Saquon Barkley shirt
- C4 eye black
- Your choice of one case of C4 Energy OR one tub of C4 Sport
Additionally, C4 is running a $1,000 contest for fans! Check C4’s social channels for entry details and official rules.

-
C4 Energy Drinks
The ready-to-drink C4 Energy line provides 200mg of caffeine in carbonated form, featuring the same performance ingredients as the powder but in convenient 16oz cans. Recent flavor additions include the Jolly Rancher collaboration with Blue Raspberry, Green Apple, Watermelon, and Peach options.

Why NSF Certification Matters, Especially for Athletes
C4 x Jolly Rancher expands! Jolly Rancher Green Apple flavor now in C4 Original and C4 Sport pre-workouts, joining Jolly Rancher Cherry in C4 Sport Ripped. Hard candy flavor meets hard-hitting performance in these nostalgic workout supplements!
The NSF Certified for Sport program tests for more than 270 substances banned by major athletic organizations. This third-party verification gives athletes confidence that what’s on the label is what’s in the product… nothing more, nothing less.
For competitive athletes subject to drug testing, this certification removes the guesswork from supplement selection. Every batch is tested, and the results are publicly available through NSF’s database.
The Bottom Line
While celebrity endorsements are great, what’s remained longer in this industry than any endorsement contract is C4’s commitment to quality. We’re getting close to the point where C4 was around before some of its users were even born — now that’s time-tested trust. The brand’s expansion from a single pre-workout to a comprehensive lineup of performance products shows its dedication to meeting athletes’ diverse needs.
Whether you’re a professional athlete requiring NSF certification, a weekend warrior looking for an edge, or someone just starting their fitness journey, the C4 lineup offers options backed by science and tested for safety. The Barkley partnership simply reinforces what many athletes already know: C4 delivers the energy, focus, and endurance needed to push through challenging workouts.
