Today, as yesterday, the name Animal stands for trust, integrity and a unique no nonsense approach to the game. Animal also represents a group of products that have stood the test of time, proven again and again in the labs, and in trenches where it counts most... The gym and the stage. Dedicated to serious nutrition for the serious athlete, Animal is your choice when it comes to complete and comprehensive supplementation. Animal. The choice of champions. What Animal Flex is Rock solids. No, we ain't talking about thick slabs of meat that hang from your frame-those are easy to see, simple to assess. We're talking about your joints, bones, ligaments and other support structures that make lifting possible...The stuff you take for granted, what you can't see but can definitely feel when there's a problem. All too often, lifters focus only on building strength without thinking twice about the underlying support structure. Truth is, you are only as strong as your weakest link. If your weakest link are your joints, then you increase the risk of injury and that mean's you're out of the game. Now you can't afford that, can you? Didn't think so... Our Ironclad Guarantee Animal is dedicated to being the best in the business, no two ways about it. If this product doesn't meet with your tough requirements for any reason, let us know. When it comes to standing behind our products, we don't mess around. That's the truth.
