Good point - my guess is that Voet used a lab that couldn't achieve the Cologne group's limits of detection. Someone help me out if I'm wrong, but wasn't Voet writing about how things were done in the early 90s? LOD would probably be 100 to 500-fold higher in those days - the preferred assay...

I absolutely agree. I don't need to see stability data from human blood. We draw reasonable conclusions from surrogate or analogous measurements all the time. Many with science backgrounds are aware that enzymatic degradation shuts down (not slows down) at low temperature, and that oxidative...

Good addition to the knowledge base. Someone should set up a Contador wiki! It think it's becoming obvious that if clen were in his blood bags it would end up in his urine. It still seems like a rookie mistake to me, given that whoever was in charge of a (putative) blood doping plan would...

Agree. I'm not used to seeing any stability data in cold whole blood in the literature. I'd expect that if blood was bagged and stored during a clenbuterol dosing cycle there would be plenty of drug left after 6 months to give a urine positive. But from everything I read about sophistication...

I did indeed read your post. I was unable to find data on plasma or blood stability, I didn't say there wasn't data on metabolism and PK in vivo. Won't be the same at all in a bag. Agreed that we can conclude that if the urine concentration is low, the plasma level is low as well. That's...

A couple of things to be aware of: 1) the number 50pg/mL refers to a concentration, not an amount. We don't have any data - there isn't any - to suggest how much urine AC passed in 24 h, so it's inappropriate to guess at the amount in his body. Concentration is a surrogate measure of drug...
