ANS Performance has launched one of its two new N-Series protein powders, seeing the original N-Pro joined by the extreme gainer N-Mass less than a month after it was unveiled. The supplement has been introduced direct through the brand’s website, where you can now purchase it in its one massive 15lb size. The price on the 42 serving N-Mass, or 21 serving if you want its promoted 55g of protein, is $74.99. While there is only the one size to choose from, ANS does have it in a total of three traditional flavors with Chocolate, Vanilla and Cookies & Cream.
