Not sure if this was posted before. Interesting to hear it from the "horse's mouth."

SPIEGEL: With Marion Jones ...
Heredia: ... it was about the recovery phases. In 2000 she competed in one event after another, and she needed to relax. I gave her epo, growth hormone, adrenaline injections, insulin. Insulin helps after training, together with protein drinks: insulin transports protein and minerals more quickly through the cell membrane.
Heredia: There are tablets for the kidneys that block the metabolites of steroids, so when athletes give a urine sample, they don’t excrete the metabolites and thus test negative. Or there is an enzyme that slowly consumes proteins - epo has protein structures, and the enzyme thus ensures that the B sample of the doping test has a completely different value than the A sample. Then there are chemicals that you take a couple of hours before the race that prevent acidification in the muscles. Together with epo they are an absolute miracle. I’ve created 20 different drugs that are still undetectable for the doping testers.
