Promino NSF Certified for Sport® to Support Team Canada's Elite Athletes with Low-Calorie Amino Acid Nutrition Designed for Recovery, Strength and Performance

BURLINGTON, Ontario – June 4, 2026 — Promino Nutritional Sciences, Inc. (CSE: MUSL) (OTCID: MUSLF) (FSE: 93X) (“Promino” or the “Company”), a performance nutrition company focused on muscle health and recovery, is pleased to announce that its flagship Promino NSF Certified for Sport® product has been named an official nutrition partner of Team Canada Speedsoft as the team prepares to compete in international competition during the 2026 season.

The partnership will provide Team Canada athletes with access to Promino's proprietary amino acid formulation, a low-calorie, sugar-free alternative to traditional protein supplements designed to support muscle recovery, strength and athletic performance.

Speedsoft is one of Canada's fastest-growing competitive sports, requiring a unique combination of physical endurance, explosive movement, reaction speed, strategic thinking and sustained mental focus. Through this partnership, Promino will work alongside Team Canada athletes throughout training and competition while increasing awareness of the Company's sports nutrition platform among athletes and active consumers.

Promino NSF Certified for Sport® is formulated with essential amino acids and is independently certified through the NSF Certified for Sport® program, helping provide athletes confidence that the product has been tested for quality and compliance with major sport governing body requirements[1].

"Speedsoft athletes represent the next generation of high-performance competitors," said Jordan Mosca, Director of Marketing at Promino. "Their sport demands a combination of physical readiness, recovery, focus and consistency. We are proud to support Team Canada with a clean, convenient amino acid solution that aligns with the needs of modern athletes seeking effective recovery and performance nutrition without excess calories or digestive discomfort often associated with traditional protein products."

Mike Montanaro, who operates Action Airsoft which is the major sponsor and training facility of Team Canada Speedsoft, added, "We are excited to partner with Promino as the team prepares for international competition. Our athletes train year-round and place significant importance on recovery and performance nutrition. Promino's NSF Certified for Sport® designation and athlete-focused approach make this a natural fit for our program."

The sponsorship will include product support, athlete engagement initiatives, social media collaborations and promotional activities designed to showcase the role of sports nutrition in supporting athletic preparation and recovery.

The Company believes the partnership further strengthens Promino's growing presence across amateur, collegiate and professional sports. Recent athlete and sports partnerships include Major League Baseball legend José Bautista, Stanley Cup Champion Jack Eichel, multiple NCAA Division I NIL initiatives and the Company's designation as the Official Protein Drink of Las Vegas Lights FC.
