THINK TANK, produced by Boost Oxygen, is a revolutionary nootropic taken by inhaling 95% pure oxygen infused with organic rosemary aroma. We think of it as an epiphany. It’s not a stimulant drug, amphetamine or methylphenidate. It’s not a multivitamin that has to work its way through the liver. It’s not caffeine. It’s simply a 100% all natural, healthy and safe fuel for your brain. Rosemary oil has been used for centuries as aromatherapy for cognitive support.
