Managing Director James Phillips explains, “There are a number of all-on-bodybuilding supplements on the market at the moment. We’ve always see OSX as the market leader in terms of composition and quality since it contains numerous premium ingredients like Creapure Creatine and has always been free from soy protein. But now we’ve really taken things to another level with OSX. The partnership with Albion®, the addition of Betaine Anhydrous and the work with LAB2PRO® means that OSX is in a different league”.
