Depends how you define PEDs. Floyd has brittle hands. He takes shots for that. Jerry Jones down in Texas has been making a serious run on getting big fights that normally occur in Vegas to come to the Cowboys' stadium, and he's landed a few. Floyd will not go. Texas tests for whatever he uses for his hands, Nevada does not. He is also known to have employed IV's at least once to manage his bodyweight between the weigh-in and the fight 24 hrs later. Might not be a drug, but it is not exactly a natty approach to things, he is not Snow White in the performance enhancing opportunity dept.
Agreed, besides god given talents, his work ethic IS way beyond what most boxers and other athletes do.
I remember when people originally started making a big deal about this...I'm on the fence...I don't agree with how he got away with the notification process of IV injections, but I guess it pays to have friends in high places, and just like any other sport, the bigger the star, the bigger the broom...but...until he comes back dirty from testing after a fight, not much can be said about it.
So as far as I can see the situation is this:
1) Lidocaine isn’t a banned substance on the WADA or USDA lists and isn’t specifically banned by NSAC.
2) Despite that, NSAC do not allow its use on fight night or in the immediate buildup to a fight.
3) While Floyd and his camp have tacitly admitted to using Lidocaine, this has only been during the training for bouts rather than during for bouts themselves. This is in contrast to Honeyghan and Oscar who appeared to use it during the bouts themselves.
4) Lidocaine has been tested for in Nevada, at least after Mayweather/Hatton, and Mayweather came back clean.
Now the story that goes round the internet is that Mayweather is using this mysterious lidocaine substance and that Nevada has some special rules that allow him to do so while every other state doesn’t and views it as illegal. The simple issue here is that there’s no evidence of this (and the articles that say that are incredibly… and I suggest deliberately… vague about it). I can see no evidence that any… let alone a majority… of other states ban the use of Lidocaine in all circumstances and there’s remarkably little evidence that they even ban it in the week leading up to a bout like Nevada do; if anything, Nevada appears to be one of the harsher states when it comes to the regulation of lidocaine.
