"You can take a substance that works in your system, but then you take this over here that's not banned, and this over here that's not banned, but if you mix them together, you've got a banned substance in your system"

This quote by Lawrence Taylor is describing the threats of mixing compounds that are not banned individually, but when integrated, produce a banned substance. Taylor is cautioning that even if a substance is not prohibited, it can still threaten when blended with other compounds. He is emphasizing the significance of understanding what compounds remain in your system and how they connect with each other. Taylor is likewise recommending that professional athletes should beware when taking any compounds, even if they are not prohibited, as they might still be dangerous when integrated with other substances. This quote serves as a tip to professional athletes to be aware of what substances they are taking and how they connect with each other, as blending substances can lead to a prohibited compound in their system.
