Muscletein was one of the best proteins available back in the day. German American Technologies had the formula, quality, price and best taste. Since it was deleted and replaced by Prolein GAT have been hanging out for something better. Supertein is a new protein powder releasing this year. Unlike Prolein it could be that 5lb powder all the fans have been waiting for. Along with JetFUEL Superburn, GAT have a top line up for 2012.
