Lightening in a bottle was the very first potion I ever purchased. It is supremely potent. To have it in a bar is a game changer. I keep it in my work locker. My days are often long as I am up at 3:30, opening the gym at 5am, and sometimes finishing the day teaching a 6pm class! This bar works to keep my energy levels burning bright through it all❤️ its a must have.
