Zoro, I think the problem with USA junior cycling and the teams mentioned is not specifically that people here think they are definitely doping from age 14 onwards (although some in the Clinic seem to think everyone who competes dope). There is undoubtedly some fantastic young talent in those teams. The huge worry is that the TEAMS, managers, coaches and moneymen are the same people who successfully doped a whole generation including Levi, Hincapie, Casey, Lance, Tyler - the list goes on and on...
Why should these people be entrusted with our kids??? Why should they be beyond VERY heavy suspicion? They have such a bad reputation and dirty history that it should be up to them to prove innocence in this case, not for us to prove them guilty (many of them already are guilty from previous work with the doping riders forementioned).
It's taken as read that these development teams are preparing these kids (mentally, not necessarily with syringes like the USA olympic team) for what comes next in the espoirs and pros and it ain't pretty. Mentoring by people who have been part of the problem is NOT the way forward to rid cycling of doping. Taking and promoting supplements (which is where this thread started) is not a great place to start juniors' thought processes around what they put in their bodies. Having elite junior "teams" with no grass roots foundation other than as a feed for Weisel's USAC organization is also very unhealthy. These kids (and I'm talking 12-18 ages) should be with LOCAL teams where they can be mentored by local riders and coaches who have a real world grounding, not masters from the dope-ridden world of pro-cycling.
BTW, no USAC junior I know of has been caught doping. But I've also never seen doping controls in 99% of USA junior races I've been to. Same goes for age-checking.
