Doping leaves cues such as weird looking bloodwork(off the charts high hemoglobin for example), overdeveloped muscles, deepened voice, etc...
If WADA wanted they could find the dopers.
The problem is there isn't enough out of competition testing. There is no reason athletes near a world record as well as championship finalists shouldn't be tested multiple times a month, maybe even daily. Something like 100 tests a year for these athletes would help uncover the cheats.
The former head of WADA David Howman says doping always remains ahead of efforts to catch the dopers. He says doping is "more sophisticated" than antidoping. That is the main difference today from doping in yesteryear - it is immeasurably more sophisticated, which means more efficient, more targeted, more subtle and harder to detect - in some cases virtually impossible. It is basically game-over for clean sport. We can see it at these world championships - the drugs are winning.
We learned from BALCO that it is relatively easy to change a molecule so that it retains it’s function but can evade detection. Most people have no understanding of how challenging detection can be. What are you detecting - a parent molecule? A metabolite? How are you detecting - chromatography? How do you standardize?
I don’t know for sure, but I strongly suspect that computational pharmacology allows a good portion of toxicology work to be done on a computer as well. So, adding some side groups to the molecule can make it undetectable and you can avoid killing people with it (if you care) by running some models.
I personally think that most people who get popped do so because of cross-contamination and that it only occurs accidentally. I think this goes a long way towards the Burritogate case on another similar ones.
it doesnt work that way.the east germans were notorious for what they could do in the gym,and they werent hyper muscled like todays athletes.the difference is these days theyre using cocktails of different drugs.insulin,hgh,clenbuterol,nandrolone,winstrol,anavar,the clear.in the past it was usually just turinabol,or dianabol on their own in low doses.some might have used primabolan or masteron,again on their own..
