Burlington, Ontario--(Newsfile Corp. - February 19, 2026) - Promino Nutritional Sciences Inc. (CSE: MUSL) (OTC: MUSLF) (FSE: 93X) ("Promino" or the "Company") announced today that a major U.S. retail partner will expand Rejuvenate Muscle Health™ into an additional 2,105 stores, with rollout set for mid May 2026.

The expansion pushes the total number of North American points of distribution very near 10,000 points of distribution, marking a significant milestone in scale for the fast-growing functional beverage brand.

Since launching with this retailer in September 2025, Rejuvenate Muscle Health™ has established a strong collaborative partnership grounded in category alignment and long-term growth strategy. The retailer's decision to significantly expand distribution reflects confidence in the brand's ability to drive incremental category growth, attract new consumers, and support evolving shopper demand across active aging, preventative health and GLP-1 supportive nutrition.

"We value the strength of our retail partnerships and the shared commitment to improving consumer's health," said Vito Sanzone, CEO of Promino. "We support our partners with disciplined execution, strategic marketing investment, and innovation that brings new consumers into the set."

Further strengthening its retail credentials, Rejuvenate Muscle Health™ was voted WINNER - Best Drink by pharmacy, grocery, and e-commerce buyers at the September 2025 program hosted by ECRM, underscoring broad buyer endorsement across multiple channels.

Positioned within the adult functional beverage category, Rejuvenate Muscle Health™ is formulated with a clinically informed essential amino acid blend designed to support muscle protein synthesis, recovery, and active longevity — a segment experiencing accelerating demand across performance, healthy aging, and wellness consumers.

The May rollout will be supported by expanded production capacity and retail activation initiatives aimed at driving sell-through across the enlarged footprint.

Promino continues to advance additional retail expansion discussions as it builds scale in the functional beverage and muscle health space.
