As we pointed out above, there are treatments that the U.S. does not allow to be performed on U.S. soil. But let's talk about the treatments the U.S. does allow. These are the treatments that address pain relief, cosmetic, and anti-aging. If a knee pain treatment in the U.S. contains 5 –6 million stem cells, our treatments typically contain approximately 110 million stem cells. This increase in stem cells magnifies the effectiveness of the treatment significantly.
