Considering the vast number of competitions that are held, many with different substance lists, it would be difficult to narrow down which ingredients in our products comply with your competition. Our product ingredients are legal under U.S. law. To keep things simple, we ask that you cross-reference our product ingredients listed on our website, Animalpak.com, and compare it to the requirements of your competition. The safest way to ensure your compliance is to contact your sanctioning authority (whoever is hosting the event and conducting the drug testing) and provide them with the label ingredients. Unfortunately, with lists constantly changing, we cannot answer this question definitively, but we can guarantee that the contents of our products stay consistent. If you bought a product from us and cannot use because of your competition, we will back it up with our IronClad Guarantee.
