Apex is a performance enhanced magnesium chloride (MgCl2) brine but is vastly different than other magnesium based enhanced products. Rather than add in substantial amounts of additives that work alongside the MgCl2 in order to improve performance, they opted to simply improve the performance of the MgCl2 itself without diluting the concentration of the active ingredient. Simply put, Apex has taken MgCl2 and made it Better - Faster - Stronger.
