Invictus recently published an ebook called "12 Banned Substances Every Athlete Needs To Know Before Competing," written by Invictus master coach Calvin Sun. The ebook provides athletes with information regarding unexpected banned substances that might be in commonly-used medicines or supplements. 

As CrossFit has risen in popularity, so has the testing. Many athletes and teams have been suspended and stripped of participation in the CrossFit games, just for taking normal over-the-counter supplements or medicine without knowing ingredients include a banned substance. 

Invictus offers their ebook for free to all athletes and teams. You can download the ebook here!

“I didn’t know” won’t cut it anymore, and the responsibility is on the athlete to be aware of what's in their body.
