What percentage of CBD in hemp rub?

How much CBD is in our tubes. To clarify, the "MG" that we list on our products is the TOTAL amount of CBD in that product. So in our Cold Therapy Hemp Rubs, there's right around 100mg CBD concentration. 

To get that amount of CBD in the tubes, we have to formulate it with more hemp extract. The hemp extracts we work with typically have a 75-80% concentration of CBD. So to do some reverse math, to get 100mg of CBD in each tube, there's actually around 125-133mg of hemp extract per tube (100mg divided by 0.75-0.80)
