There's an epidemic in the supplement world, and it has to do with pre-workouts.

What's the problem? Several things, but to name just a few: missing ingredients, other ingredients being underdosed (and thus ineffective), and even some brands flat-out lying about what's in their pre-workout.

Fortunately, you can find out most of what you need to know about a pre-workout — and whether or not you should buy it — by simply flipping the bottle around and looking at the Supplement Facts label.

In this video, Dr. Jim Stoppani, creator and formulator of the industry-leading pre-workouts Pre JYM and Pre JYM X, discusses the main issues with most pre-workouts and what to look out for.
