Not a chemist but the way DMSO is absorbed into the body how are they going to tell whether it was adminstered topically or intravenously?
For those who don't know DMSO is a by-product of the wood industry which is used as an anti-inflammatory and has the ability when mixed with other drugs to help them penetrate deeper into the body. Leaves a strong lingering garlic taste that some people like me can't stand. You would mix it in with other linaments as a leg rub or or as intravenous jug a couple of days out before a race.
Back in the 70's it was dirt cheap until a 60 minutes episode and popularity caused the price to quadruple.
