About Proven4

Innovation Meets Experience

The era of transparent, high-performance sports supplements is here. Proven4 was born from the combined expertise of two industry leaders: Shelley Winslow, a specialist in regulated manufacturing standards, and Frank Catalanotto, a 14-year Major League Baseball veteran. Together, they have merged the precision of quality-controlled production with the real-world needs of professional athletes to create a supplement line that elevates performance without compromise.

The Proven4 Approach

At Proven4, we are obsessed with creating products that support an athlete’s journey—from the professional stadium to the local fitness center. Our formulas are the result of years of rigorous development, designed to comply with the strict standards of the World Anti-Doping Agency (WADA) while providing the "everyday athlete" with a level of purity rarely found in the supplement aisle.

The Proven4 Product Line

Our formulas are crafted to promote peak physical output and support efficient recovery across three core pillars:

• Pre-Game Formula: Designed with moderate caffeine to promote energy and support mental focus. Our pre-workout provides the clean fuel you need to support endurance and strength.

• Recovery BCAA + Electrolytes: This stimulant-free formula supports muscle tissue repair and promotes optimal hydration, making it the perfect choice for post-workout recovery or late-day training.

• Creatine Monohydrate: One of the most researched supplements in history. Our formula helps promote muscle strength, support power output, and promote lean muscle mass gains.

Why We Insist on NSF Certified for Sport®

Because we work side-by-side with athletes, we refuse to cut corners. We take the extra step to certify every product to NSF Certified for Sport® standards. This process ensures:

1. Banned Substance Screening: Safety for competitive play in the MLB, NFL, NHL, and beyond.

2. Label Claim Verification: Guaranteed that what is listed on the label is exactly what is in the powder.

3. Contaminant Testing: Promoting total peace of mind for every health-conscious consumer.

At Proven4, transparency is our priority. You can verify our current certifications and tested batches directly through the NSF Certified for Sport® Directory.

The NSF Difference

Our Word is Our Bond

To earn your trust, we believe in proof, not promises. Instead of simply stating that our products are clean, we chose to undergo the most stringent testing in the world. The NSF Certified for Sport® program is the gold standard in third-party verification, ensuring that every claim printed on our label is a fact, not a marketing tactic.

What is the NSF?

The NSF is an independent global organization dedicated to protecting human health by holding the supplement industry to the highest possible standards. For a product to wear the Certified for Sport® mark, it must survive a rigorous, multi-stage audit that many supplement companies simply cannot pass.

The Three Pillars of the NSF Mark

Acquiring the NSF’s Certified for Sport® Mark means the product has met these three critical criteria:

• Rigorous Banned Substance Screening: Every batch is tested for over 280 substances banned by major sporting organizations.

• 100% Label Accuracy: The NSF verifies that exactly what is listed on our label—and in those precise amounts—is what is actually inside the bottle. No hidden fillers, no "pixie-dusting."

• Facility & Purity Audits: Our production follows every FDA-mandated cGMP (current Good Manufacturing Practice) and rigid quality-control procedure to ensure the product is free from unsafe levels of contaminants or masking agents.

Internal Quality Assurance (QA)

Our commitment to safety doesn’t start and end with a third-party seal. To maintain our high standards, Proven4 follows a strict internal QA protocol:

• Raw Material Verification: We verify the purity of every ingredient before it enters our blending process.

• In-Process Audits: We monitor production at every stage to ensure formulation exactness.

• Finished Product Testing: No batch is released until it is confirmed free of contaminants and banned substances.

• Full Traceability: We track every ingredient from the source to the final bottle for total accountability.

• Our Commitment to Digital Security: Just as we verify our supplements through NSF, we verify our store’s security through annual PCI DSS 4.0 audits. This ensures your payment information is handled with the same pharmaceutical-grade integrity we apply to our formulas. See our PCI Compliance Certificate here.

The Choice of Champions

The NSF Certified for Sport® program is the only independent third-party certification recognized and trusted by the world's most elite athletic organizations, including:

• The Big Four: MLB, NFL, NHL, and NBA.

• Major Global Leagues: PGA, LPGA, MLS, and the CFL.

• Governing Bodies: USADA (United States Anti-Doping Agency) and the Ironman competition.

Why It Matters to You

Whether you are a professional athlete whose career depends on a clean test or an everyday fitness enthusiast who values their long-term health, the NSF mark is your guarantee of safety. At Proven4, we take the extra step so you can take your supplements with total confidence.
