Here's a fun example: So, Tommy D... Here's a guy that has used o2 vector doping, and with some success. But when you test him, without o2 vector doping, you quickly see this guy has massive aerobic ability. O2 transport isn't the limiting factor with his body/mind. However, he is not a mentally strong athlete. He succumbs to nerves and pressure very easily.
So, in looking at his physiology and psychology, the rate limiting factor is the latter, not the former. So, working on that makes huge strides. Giving him o2 vector doping is akin to putting a bigger engine in a car with a flat tire, because you want it to go faster. yes, it will make the car with the flat tire go faster, but you could just go ahead and fix the flat tire instead?
This isn't true with with lots of guys. Imagine a psychologically strong athlete that has great tactical sense, and is muscularly very strong as del, but who doesn't have a great o2 delivery system. This athlete benefits perfectly from o2 vector doping, and it would be difficult for them to perform as well without it. So, as a manager, i need to know that going in.
With Tommy D, I knew I could get great performances out of him, clean, but it would take some unconventional work. This is not always true.
