I've got news for everyone. Just about every fighter now days is taking a cocktail similar to the following;
-HGH
-E.P.O
-Cortico's out the yen yang
-Nolvadex to boost natural levels (don't test me, this has been proven to bring you way up)
-Mucho, mucho pain killers
I know a fighter that lives in Vegas who confessed to me this is true. When you think about it none of these things are tested for and help tremendously in the endurance/recovery game. Even the Nolvadex is just used to boost test levels to recover better. Everything else is a given.
