AST Sports Science is a long standing supplement company that credits themselves with the introduction of the first whey protein product back in 1992. Recently we saw the veteran brand drop one of their more iconic supplements, the mass protein Muscle XGF. Unfortunately since it’s departure from their website and most AST stockists, nothing has come to replace the weight gainer. The latest update from the company is sadly another notification going the way of Muscle XGF with the brand dropping yet another fan favorite. Beta-X AST Sports Science’s patented beta alanine product, has had it’s original caplet form listed as discontinued on a number of stores, as well as no longer appearing on the company’s official website. While fans of the supplement may be disappointed to hear that their endurance driven product is now only available in powder form. AST have tried to make it up to their followers by swapping out their regular beta-alanine, for the branded and relatively popular form of the ingredient, CarnoSyn.
