Mutant’s latest and greatest supplement has surfaced at it’s first US retailer. Not too long after the brand originally previewed their slow release protein simply titled Micellar Casein, it went on sale through Mutant’s UK and Canadian websites. While the third protein powder from the brand has still yet to be added to their US site, it has found it’s way into Supplement Central. The store that always seems to be the first to get things organized and online have shown up with both flavors of Mutant’s Micellar Casein. Chocolate milk and vanilla ice cream can can now be purchased in the product’s one and only 4lb tub size for $54.99. Surprisingly the availability of Micellar Casein at Supplement Central actually comes with the online retailer’s own introduction of Mutant. Before their launch of the casein formula, the store didn’t have any of the brand’s products, with Micellar being one of the nine they’re now stocking.
