From the Founder

Designed to fit your life and your goals

I still care about training hard, but my life doesn’t revolve around a two-hour workout. I have a business to run, kids to raise, and a schedule that changes by the day. I developed this formula because I wanted a pre-workout that supported the way I train now, with ingredients for energy, focus, endurance, strength, and power.

I also wanted the women in my life to have more than an energy drink disguised as a pre-workout. That’s why one scoop is a real performance serving with 150mg of caffeine, while two scoops gives you the complete formula when you want more. Different people and different workouts need different things, and the formula was designed to respect that.
