Hi Matthew,
I'm also using DMSO, but never heard of a gel. That's probably because I'm based in Germany.
Well, 70% seems a lot, the percentage seems very high, but I'm not sure.
You can check on DMSO websites if the percentage is ok.
I only drink it and drinking it, one should use only 15% DMSO.
So for ex. one glass of water and a teaspoon of DMSO.
Your skin has to be really clean before you put on the DMSO, because DMSO goes directly into your body and takes substances left on the skin with itself.
And don't forget to never contact DMSO with plastic.
DMSO would take substances out of the plastic and would transfer it into your body.
And it should be used only once a day.
Besides that I guess DMSO is really good for healing,
