Red Powder?

More news is coming out of the Operacion Puerto affair, which seemingly has links to several different locations around the world. German magazine Der Spiegel reported that the Spanish Guardia Civil found fake EPO, originating from China, at Dr Eufemiano Fuentes Madrid laboratory, as well as anabolic products from a "secret laboratory". There are also reportedly small groups of "doping doctors" all over the globe with links to Dr Fuentes.

In their searches, the Guardia Civil found four envelopes containing a red powder, which is able to neutralise synthetic EPO so that it doesn't show up in urine tests. It's guessed that riders rub the powder on their hands and drop some of it in as they give a sample.
