• Largest Production Order to Date: Approximately 3.5 million stick production run (≈225,000 units) initiated to support increasing retail and e-commerce demand, with product expected to reach market starting in April.
• Proprietary Formula with Planned Patent Filing: First large-scale run utilizing the Company's new proprietary formulation; patent filing expected in Q2 2026.
• Rejuvenate Channel Expansion: In addition to retail and Amazon demand, the Company is introducing TikTok Shop USA and stronger direct-to-consumer efforts in North America.

Burlington, Ontario--(Newsfile Corp. - March 16, 2026) - Promino Nutritional Sciences Inc. (CSE: MUSL) (OTC: MUSLF) (FSE: 93X) ("Promino" or the "Company") announces it has initiated production of approximately 3.5 million sticks (servings) of Rejuvenate Muscle Health® ("Rejuvenate"), representing the largest single production run in the Company's history.

The production is expected to yield approximately 225,000 consumer units across multiple count sizes and flavors, including Raspberry Burst, Citrus Blast, and two new flavor additions, Tropical Mango Pineapple and Harvest Grape. Finished goods from this run are expected to reach the market starting in April 2026.

Current demand for Rejuvenate is primarily driven by national retail distribution and Amazon. The Company is introducing a TikTok Shop USA launch in May 2026.

This production run is the first to utilize the Company's new proprietary, enhanced formulation. Promino expects to file for patent protection in the United States in Q2 2026, with additional jurisdictions to be considered thereafter. There can be no assurance that patent protection will be granted.

Rejuvenate Muscle Health® was named WINNER - BEST DRINK 2025 at the September 2025 ECRM session, based on voting by attending retail buyers.

The Company notes that increasing consumer adoption of GLP-1 weight management medications is contributing to broader awareness around muscle preservation during weight loss¹. Rejuvenate's 5-calorie, sugar-free, dairy-free amino acid format provides a low-calorie alternative to conventional whey-based protein products, which may be less suitable for some consumers due to volume and density.

"We are encouraged by ongoing demand across retail and e-commerce channels," said Vito Sanzone, CEO of Promino. "This production run supports our existing distribution and positions the Company to service anticipated growth initiatives in 2026."
