get a shot glass, rinse out with rubbing alcohol and allow to dry. Put your fina tabs(3-5 usually) in the shot glass and grind up with a blunt instrument, the butt end of a kitchen knife usually works just fine. Add 2-3cc dmso liquid and put in microwave for about 5-6 seconds. Try not to boil. Remove and stir. Repeat this until all the fina is dissolved. once dissolved, you can add a few drop of glycerol to aid in the skin penetration as well as to protect the skin somewhat from the dmso... YOu can also add a few drops of high % alcohol like 151 rum or vodka to help dilute the dmso. If the solution starts to turn cloudy, add a drop or two of dmso to clear it up. You can now rub it on a clean skin surface, I like shoulders and forearms. No need to rub it in, just keep applying with fingertips until all the dmso is applied. No need to cover with saran wrap, in about 15-30min's it will all be absorbed and you can wash it off., Expect some redness and/or burning sensation at the application site, good idea to rotate sites, shoulders, forearms, thighs, whatever to avoid chronic irritation. good luck.
