All right, here’s an interesting question that we get from athletes, “What is a non-approved substance and why is it prohibited?” There’s a non-approved substance category on the WADA Prohibited List unser “S zero.” These are substances that are not approved by any government regulatory authority. And they’re not approved for human use. They may not fit in nicely into other WADA Prohibited List categories, but nevertheless, because of their potential to enhance performance, they’re prohibited under “S zero.” Some examples of these substances are peptides, such as BPC-157, and 2,4-Dinitrophenol.
