Hello!
All these protocols that you mention are doable.
When applying MMS/DMSO to the skin, in my own experience as I have done it many times, you have to be quite careful with dilutions. You might want to dilute both the MMS and the DMSO. I would never put DMSO 99%, for example, on the skin, but at least a dilution of 70% with 50% working even better. The idea is to get it to enter the skin without an adverse effect. The same with the MMS. So experiment and find the dilution that works for you. You can also use CDS and add DMSO to it.
Foot baths were part of the seminar, and are a quicker way to absorb the CDS/DMSO than the more involved body bath. Also, you should know that the body bath depletes electrons (while a shower or swimming increase it by the friction). That's why we are sometimes tired when done with a body bath. A foot bath, on the contrary, can be done while working on a desk or computer. That is also an advantage.
