I already did an advance search and nothing came up to fully answer my questions. So I thought that I would see what everyone has to say, and PLEASE ONLY PEOPLE THAT KNOW WHAT THEY ARE REALLY TAKLING ABOUT OR HAS A LINK TO VERIFY. So i have been taking animal pak for about four weeks and I have seen some improvements but what weirds me out a little is that when I urinate after taking them my pee is a neon yellow green color. I have two friends that are taking them to and have the same thing happen. I have also noticed that other people in this forum saying the same thing. My question is does anyone really know why this happens?
