To the poster who kicked this off, two questions:
1) what is being masked? It must be something taken during the race, yes, otherwise the masking could have been done ... well, less publicly?
2) what do you think the masking agent is? Are you suggesting this is like the flake of soap powder in the urine that used to be used to spoil tests? Or are you suggesting that the gummy bears contain some agent that changes the evidence of doping within the body, say turns EPO in, I dunno, sugar? Or are you suggesting it's just the normal diuretic, used down through the ages of anti-doping as a way of reducing the concentration of metabolites of flushing them from the system quicker?
Having tossed this theory out there, you really do need to stand it up, explain the science. And properly explain it, not just chuck up some URLs you found when you Googled a couple of key words in the questions.
I don't know, but those are the right questions.
The gum has this pectine (hence the link to that pothead), requires chewing, allows to spare some behind the teeth, maybe to spike the sample. ... Apparently it is useful to administer caffeine and testosterone, so maybe someone produces special candy to cover up PED taken during the final.
One advantage I can see is that the soigneur only adds the modified gums at the last moment, on top of real candy. Before and after, controls would find just that. Also, it's possible that the laced candy tastes horribly and therefore there is need to take in a huge amount, like Sagan does.
At this point it would be recommended that a chemist or biologist jumps in. I only noticed a pattern that logic can't explain. Sugar intake is not good enough.
