From someone who spent 7+ years cycling on and off steroids, he would not test positive if his fight was during his cycling off period, so that is why Mayweather would want olympic style testing.
The crap about losing too much blood is just that "CRAP", a few ounces will not effect him in any way. He lost that fight because Erik Morales was better that night.
That could be true but, as you know, it all depends on the steroid, as some stay in your system well over a few weeks (test enthanate or Sust, or especially Deca) or if it is a short acting ester it can be out quick (cypionate, propionate).
If he would be cycling down, I am sure he would use some ancillaries for anti-estro or to get his natural test production going again, which would surely be picked up in a test (hcg, clomid, armidex, nolvadex, etc). The HGH test is still pretty unreliable thus far as to my knowledge, it has only caught one person (a rugby player).
Nonetheless, I agree it shouldn't be a problem for the blood to be taken, as there is absolutely no evidence the quanitities used to test for PEDs could weaken anyone. Morales did whoop his ass that night, not the loss of blood.
It shouldn't matter if he is on steroids or not because Mayweather acts like he can kill anyone in the ring, so what does it matter anyways hahaha:eyepoke:
