Good for you!
In looking up the CDS, I came across an item I bought several years ago at a friend's urging:

DMSO 8 oz. Glass Bottle Non-diluted 99.995% Pure Low Odor Pharma Grade Liquid Dimethyl Sulfoxide Super High Quality Made by DMSO Store

Stupidly, I bought FOUR bottles (economy!) for $32. Two remain unopened (and likely expired). The other two were barely used. (I'd asked my family doctor to test it out on his own knees; it's also used for aches and pains in horses; he returned it, opened but basically unused).

I do love your sense of humor. :)
