Reformulated testosterone optimisation product is powered by four human clinical studies, delivering enhanced strength, energy and focus

Published: 22-Apr-2026

PLT Health Solutions, Inc. announced that Jocko Fuel (Jay, Maine, USA), the performance nutrition brand founded by retired Navy SEAL officer Jocko Willink, is launching COMBAT TESTED 3.0, a reformulated testosterone optimisation supplement featuring TestFACTOR, PLT's clinically studied botanical complex for men's health

The new formula replaces 300 mg of Fadogia agrestis with 325 mg of TestFACTOR, reflecting Jocko Fuel's commitment to science-backed ingredients and disciplined formulation standards. COMBAT TESTED 3.0 will be available direct-to-consumer via jockofuel.com, Amazon, and select retail partners beginning in mid-April 2026.

Reformulated Around Clinical Evidence

According to Cam Fischer, Marketing Director for Jocko Fuel, the reformulation aligns directly with the brand's mission: Your mission is our purpose. "Jocko Fuel is built for serious lifelong workout diehards and those getting back on track," said Fischer. "When we evaluated the clinical data behind TestFACTOR, we saw measurable outcomes in testosterone and vitality. That's the standard we hold ourselves to — no fillers, no fairy dust, no compromises."

Ashley Freeman, Product Research & Development Specialist, Jocko Fuel's lead formulator for the new product, added that testosterone was a primary endpoint in all of TestFACTOR's clinical studies — a key factor in the reformulation decision. "Our target consumer is the active, health-conscious man — often in his mid-40s and beyond — who wants to support strength, performance, and vitality as part of a disciplined lifestyle," she said. "TestFACTOR gave us a clinically substantiated anchor ingredient." COMBAT TESTED 3.0 retains complementary nutrients such as vitamin D and boron to support hormonal balance, while centering the formula around 325 mg of TestFACTOR.

Four Clinical Studies Support Enhanced Testosterone

TestFACTOR is a patented botanical complex derived from Mangifera indica bark and Sphaeranthus indicus. The ingredient has been evaluated in four randomised, placebo-controlled trials in both trained and untrained subjects. In these studies, supplementation with TestFACTOR demonstrated:

  • Up to 19% increase in total testosterone levels
  • Up to 20% increase in free testosterone levels
  • Improvements in measures of vitality and energy
  • Support for strength performance, including grip strength

TestFACTOR was recently recognised with the "Ingredient Idol" award at SupplySide Global, underscoring its scientific and market validation.

According to Steve Fink, Vice President of Marketing for PLT Health Solutions, the partnership reflects aligned philosophies. "Jocko Fuel stands for discipline, transparency, and performance," said Fink. "By reformulating COMBAT TESTED 3.0 around TestFACTOR, they've elevated this product with a clinically demonstrated solution that supports healthy testosterone, vitality, and strength in men. We are excited to see consumers respond to this product in the market," he added.

Built for the Mission-Driven Consumer 

Jocko Fuel intentionally differentiates itself from trend-driven, neon-coloured performance supplements, focusing instead on clean, purpose-driven formulations. COMBAT TESTED 3.0 is designed for men who are committed to training, leadership, family, and long-term performance — including those rebuilding momentum and lifelong athletes alike.
