October 29, 2026

Initial order supports planned placement at 20 Balls Food Stores locations; broader independent grocery opportunity remains prospective

Burlington, Ontario--(Newsfile Corp. - October 28, 2026) - Promino Nutritional Sciences Inc. (CSE: MUSL) (OTCID: MUSLF) (FSE: 93X) ("Promino" or the "Company"), a muscle health and performance nutrition company, announces it has received an initial purchase order for Rejuvenate Muscle Health™ through Associated Wholesale Grocers, Inc. ("AWG"). The order supports planned retail placement at 20 Bals Food Stores locations in the Kansas City area. AWG is a retailer-owned wholesale grocery cooperative serving approximately 1,100 member companies and 3,500 stores across 33 U.S. states, according to AWG. Its distribution network provides a potential avenue to additional independent grocers; no further retailer listings or orders have been secured through this arrangement. "AWG gives Rejuvenate a new route into the U.S. independent grocery market," said Vito Sanzone, Chief Executive Officer of Promino. "Our first focus is the 20 Bals Food Stores locations in Kansas City." The development folows the Company's previously announced Kroger pharmacy retail test. Rejuvenate Muscle Health™ is a low-calorie, plant-based drink mix containing Promino's proprietary essential amino acid formulation and 1,000 IU of vegan vitamin D3.
