RivalUs has just launched its first Promasil spin-off with a fairly self-explanatory supplement called Promasil Casein. The product is as you could probably guess, a casein protein powder, which has very little in common with the regular Promasil protein.
Promasil Casein is a slow release protein competitor designed to feed your muscles over an eight hour period. The unique combination of protein sources the new RivalUs supplement relies on for that eight hours includes native micellar casein, regular micellar casein, hydrolyzed casein protein, and alpha-lactalbumin.
The macros making up each of Promasil Casein’s servings are actually pretty clean with 24g of protein, less than a gram of fat, 2g of carbohydrates with a gram of that fiber, no sugar, and 110 calories. Those numbers are from the product’s Max Chocolate flavor, with its other option Vanilla Overload, only being slightly different with 3g of carbohydrates and no fiber.
RivalUs fans can now grab their favorite brand’s new Promasil Casein from its official online store in just the one 2lb, 28 serving tub size. The cost on the supplement is $34.99, which is in fact cheaper than the regular Promasil or at least on the RivalUs website it is, by about 15%.
