Burlington, Ontario--(Newsfile Corp. - June 2, 2026) - Promino Nutritional Sciences, Inc. (CSE: MUSL) (OTCID: MUSLF) (FSE: 93X) ("Promino" or the "Company"), a leader in muscle health and performance nutrition, is pleased to announce that a rush supply of Promino™ - NSF Certified for Sport® was recently supplied in connection with the Stanley Cup Final.

The development comes as Promino Ambassador Jack Eichel continues to play a leading role in the Vegas Golden Knights' pursuit of a second Stanley Cup championship. Earlier this year, Mr. Eichel captured Olympic Gold as a member of Team USA, adding to an already distinguished hockey career.

Promino™ - NSF Certified for Sport® is the Company's proprietary amino acid formulation designed to support muscle recovery, performance and strength while providing a low-calorie, sugar-free and dairy-free alternative to traditional protein products. NSF Certified for Sport®¹ is one of the most recognized certifications in sports nutrition, providing assurance that products have been independently tested to meet rigorous quality and safety standards.

The Company believes increasing interest in Promino™ among athletes, coaches, trainers and sports organizations reflects growing awareness of the importance of muscle health and recovery across all levels of sport.

Promino's presence in athletics continues to expand through relationships with elite athletes and sports organizations, including former six-time MLB All-Star and Promino Ambassador, Jose Bautista. Mr. Bautista is the owner of Las Vegas Lights FC, where Promino™ serves as the Official Protein Drink and is incorporated into the club's performance nutrition program.

The Company also recently announced NIL partnerships with nine NCAA Division I athletes from Virginia Military Institute, one of the leading military colleges in the United States. Together, these initiatives reflect Promino's growing presence across high school, collegiate and professional athletics.

Promino™ - NSF Certified for Sport® is represented across high school, collegiate and professional sports programs.

"Promino was developed to support athletes striving to perform at their highest level, from high school competitors to collegiate and professional athletes," said Vito Sanzone, Chief Executive Officer. "To see Promino being associated with some of the biggest stages in sport is encouraging awareness of our brand among athletes, coaches, trainers and performance-focused consumers. We remain focused on expanding awareness of Promino™ - NSF Certified for Sport® among athletes and active consumers seeking trusted muscle health and recovery solutions."

The Company notes that the Vegas Golden Knights are not a sponsored partner of Promino, and the use of Promino™ products by athletes or sports organizations should not be interpreted as an endorsement by any league, team, or governing body.

Promino also announces that it has entered into an agreement with a third party for event marketing services. Pursuant to this agreement, Promino has agreed to issue 625,000 common shares of the Company on a quarterly basis for an aggregate of 2.5 million common shares.
