Burlington, Ontario--(Newsfile Corp. - May 26, 2026) - Promino Nutritional Sciences, Inc. (CSE: MUSL) (OTCID: MUSLF) (FSE: 93X) (" Promino " or the " Company ") today announced the launch of its next phase of e-commerce growth, anchored by the debut of its new U.S. direct-to-consumer platform, Drink Rej website, on June 1, 2026.

With initial production batches of Rejuvenate Muscle HealthTM now received and additional inventory scheduled to arrive over the coming weeks, Promino is positioned to scale a coordinated e-commerce strategy across Amazon, direct-to-consumer and TikTok Shop USA.

The ongoing production run-at nearly 4 million servings-marks a key step toward restoring consistent supply and supporting expanded participation across multiple high-growth digital channels.

The launch of "Drink RejTM" establishes a unified consumer platform across Rejuvenate Muscle HealthTM and ProminoTM - NSF Certified for Sport®, designed to drive awareness, trial, and repeat purchase through a simplified, subscription-first model.

The new Drink Rej website platform introduces a streamlined purchase experience, improved subscription functionality and a recipe-driven content hub aimed at increasing daily usage and customer retention.

At launch, the U.S. site will feature Rejuvenate Muscle HealthTM Raspberry Burst, with additional flavors-including Rejuvenate Muscle HealthTM Citrus Blast, Tropical Mango Pineapple and Harvest Grape-expected to follow within weeks as inventory continues to be received. A Canadian platform launch is expected later in June 2026.

Promino intends to replicate its demonstrated 2025 success on Amazon across its own DTC platform, while expanding into TikTok Shop USA, an emerging channel increasingly driving discovery and conversion in the U.S. supplement category through creator-led commerce.

"The momentum we experienced on Amazon starting last year sets Promino up well on the higher-margin DTC channel to build direct customer relationships," said Vito Sanzone, CEO of Promino. "As inventory continues to come online and with the launch of 'Drink RejTM,' we are positioned to scale efficiently across Amazon, DTC and TikTok Shop."

All products featured on the platform incorporate Promino's proprietary, plant-based amino acid formulation, designed to support muscle protein synthesis without the calories, sugar or dairy associated with traditional protein products.

The Company will continue to support its retail partners while leveraging its expanding digital ecosystem to drive brand awareness and demand across all channels.

The new U.S. platform will be accessible beginning June 1, 2026 at: Drink Rej website.
