While we have been left wondering about the future of Muscletech’s Arnold Classic previewed Platinum Gakic and Platinum Test Booster. The brand have gone and revealed number 20 for their Essential Series, with the line’s fourth protein powder Platinum ISO-Zero. For those international Muscletech fans the name might seem familiar, as it is exactly the same as the non-US Performance Series supplement ISO-Zero. There are a lot of things separating the two aside from the Platinum title. With the pure whey isolate protein unflavored and featuring per (27g) scoop, 25g of protein, zero fat, zero carbohydrates, and a total of 100 calories. Each tub of Platinum ISO-Zero weighs in at 1.5lbs, although due to it’s extremely straightforward formula. It packs just one less 25g protein serving than Muscletech’s other fine Platinum protein, 100% ISO-Whey. As mentioned, the product does look to be an unflavored only supplement. Which we feel could see the brand become even more competitive with their new range of proteins. Especially if ISO-Zero follows the Essential Series trend and comes in a double or more size tub.
