It actually turned out to be a letter, anyway as requested:
"We have recently been involved in
the care of a 21 year old amateur
bodybuilder, who was admitted after taking
an excessive amount of insulin intrave
nously. He developed severe brain damage
after prolonged
neuroglycopenia. His case
brought several points to our attention.
Since anabolic steroids have been desig
nated illegal in competitive sport, athletes
have been looking for alternative drugs to
help them put on muscle mass and burn off
fat. With little understanding of the poten
tially serious side effects, they are now using
preparations that have no proved benefit in
sports training.
After reading several bodybuilding
magazines and scanning numerous internet
web sites we have realised that the extent of
misuse is considerable and growing...
...It is worrying
that a drug such as insulin is being
described as “the most powerful anabolic
hormone on the planet”3 to a readership
that can be obsessive and often has a poor
body image.4"
