The formulation of Hustle Drops was inspired by recent research on athletes using peppermint oil. Athletes exposed to peppermint were all around faster, stronger, and tougher. The main constituent of peppermint oil is L-Menthol, a potent muscle relaxant and local anesthetic. The performance benefits, based on the current general consensus across studies, appears to be the expansion of their airways and the increased availability of oxygen. Hustle Drops' two main active ingredients are properly sourced, blended, and tested, peppermint oil and L-Menthol.
