"Also make certain that you get the pharmaceutical grade. We got ours from a site called dmso.com "
The DMSO sold on this site is NOT pharmaceutical grade, it is industrial grade and is produced in China where there may be issues of heavy metal toxicity.
www.jacoblab.com has a pure grade of DMSO. It is also the site of the doctor and scientist, Dr Stanley Jacob who developed DMSO in the 70's for organ transport.
Please inform yourself fully of the issues of using and obtaining DMSO. There is much misinformation on the internet about DMSO. It is up to the individual to triple check all information and sources.
