What the tCheck does is similar to the way one would check their cholesterol at home. The purpose is to give you an understanding of your cholesterol levels without the need for an in-depth breakdown that might take days. tCheck gives you a CBV number, or botanical Compound By Volume, which is the aggregate compounds in the infused solution. With the CBV reading you can determine the amount of un-infused and infused oil you need for any recipe. To help with the process, the calculator is a tool that helps determine exactly how much you need for a desired dose.
