The bottom line then, is that doping seems to work VERY WELL. It’s still difficult, if not impossible, to put an exact number to the benefit, though the data of Franke et al give a pretty good indication that it’s at least 15% in those power based sports. It may be slightly less for endurance based sports, like cycling. But as i wrote yesterday, there’s substantial evidence that hormone levels, particularly testosterone fall during the course of a race like the Tour. And so if Floyd Landis and others are using the drug, the benefit would come from defending this drop-off, which promotes recovery and hence allows them to maintain their form throughout the Tour. In theory then, the systematic use of drugs will have a large effect in cycling, not because it acutely boosts performance, but because it allows it to be maintained. Think of your own training – you always have good days and bad days. But what if I said that by using a drug, like testosterone, you could drastically reduce the number of bad days – that is what these drugs will do for cyclists.
There is a big controversy on this matter. There are some sources, which tells that turinabol depot is detectable up to 18 months and oral turinabol is detectable up to 12 months in worst-case scenario. Some other people on the forums tell that 6-8 weeks in more than enough. However, we cannot understand where they all took such huge and unreliable numbers from. Doping tests rarely shows chlordehydromethyl-testosterone indeed and it was widely used in 60es and 70es so there is a good evidence that real detection times are much shorter. Most likely this mistake happened because athletes used some long-living substances like deca long with it. Or, maybe, these sources misrepresent turinabol with the same deca, we have seen some product descriptions, supposedly made for turanabol but after reading we understood they were just copypasted from deca descriptions, stupid, isnt’ it? Also, just as brain-storming: YES, it quickly leaves the body and not detectable in the urine tests, but probably modern blood tests can detect it for longer time, especially when using injectable turinabol.
