From Jim Davies
If it’s effectively impossible to test athletes for artificial insulin,
erythropoietin or similar drugs
(11 August, p 4),
why not add a marker chemical to the drugs during manufacture?
It would have to be harmless, persistent in the body and not found there
naturally. It would also have to be added to the drug by all manufacturers.
But it shouldn’t be too hard to persuade the pharmaceuticals companies to do
this, especially given a bit of political pressure from the world’s combined
sporting bodies.
