Bute has no affect on a horse's performance after 12 hours, yet its withdrawl is 7 days. The chemists can tell, by the way the drug breaks down in the body, when it stops having any direct affect, despite it still being present, yet if you give it at 5 days, not 7, and get a positive, you're out for 6 months for something that wouldn't help you in a race anyway!

Being a banned substance in Australia doesn't mean something is performance enhancing... and for the record, there is also a threshold of allowable DMSO in a horse's system. While it can be used in conjunction with other substances, remember the positive here is for DMSO only and nothing else.

Witchazel is also a carrier and there are many others...
