MMUSA, Muscle Marketing USA, were originally founded in the 90s with the goal of creating the worlds first liquid creatine serum - which they believe they have done with MMUSA ATP Creatine Serum. In subsequent years they have realised new versions of liquid creatine and also liquid thermogenic products like thermo serum.
