.... DHMO?
http://www.dhmo.org/facts.html
"One technique commonly used by endurance
athletes in sports such as distance running and
cycling is to take a large amount of DHMO
immediately prior to a race. This is known within
racing circles to dramatically improve performance.
Sports-medicine physicians warn that ingesting
too much Dihydrogen Monoxide can lead to
complications and unwanted side-effects, but do
acknowledge the link to improved performance.
DHMO is not currently considered a banned
substance, so post-race urine tests do not
detect elevated or abnormal levels of DHMO."
"Some of the known perils of Dihydrogen
Monoxide are:
Death due to accidental inhalation of DHMO,
even in small quantities.
Prolonged exposure to solid DHMO causes
severe tissue damage.
Excessive ingestion produces a number of
unpleasant though not typically life-threatening
side-effects.
Gaseous DHMO can cause severe burns. "
