EPO, HGH, or some other designer steroid that doesn't stay in your blood for past 72 hours. Whatever. The specific substance doesn't matter.

The most of important part of this thread, is to highlight the fact that using the drug during training will give you an unfair advantage on the fight night. It doesn't need to be in your system on fight night (or on other fixed date blood tests) to give you a seriously unfair advantage against a clean fighter.

Olympic style random testing prevents this. I can't see why so many people are defending Manny for this. If the roles where reversed, and it was Floyd trying to prevent any possibility of being tested fairly, every fight forum on the internet would crash due to the number of people posting about it.

Manny shouldn't be allowed to cheat, just because he has convinced the general public he is a humble likable guy.
