Dan Henderson Ignores Own Past in Criticizing Lyoto Machida's PED Admission

This Saturday's UFC on Fox 19 card suffered a late blow on Wednesday when Lyoto Machida declared the use of a banned substance, resulting in the cancellation of his co-main event bout with Dan Henderson.

According to an article from Tristen Critchfield of Sherdog, Machida acknowledged taking a supplement containing the performance-enhancing substance DHEA. The UFC addressed the issue in a statement posted to its website.

"Machida stated that he was unaware that the substance was prohibited both in and out of competition," the statement read in part. "Given this information, UFC officials have elected to remove Machida from his scheduled bout against Dan Henderson this Saturday in Tampa, Florida. Henderson will be re-booked for a new bout in the near future."

But UFC officials weren't the only ones to weigh in. Soon after the news broke, Henderson took to Twitter to express his own displeasure.

It was a bold and interesting take. Although Henderson has never failed a drug test or otherwise run afoul of any MMA rule or regulation, he does have a well-documented history of using legal but potentially performance-enhancing substances.

Henderson, 45, openly used testosterone replacement therapy (TRT) until its widespread blanket ban in 2014. He was able to legally use TRT because he received a therapeutic use exemption to do so.

According to the Orange County Register's Carlos Arias, the medical purpose of TRT is to treat hypogonadism, a fairly rare condition in which the male body does not produce enough testosterone on its own.

After the TRT ban, Henderson told MMA Junkie that he "just kind of quit cold turkey," with no apparent serious side effects.

Henderson (31-14) is 2-3 since the announcement of the ban, with his two wins coming against Mauricio "Shogun" Rua and Tim Boetsch.

On Wednesday, Machida cited ignorance of the rules as the reason for the violation. In more than one way, this may be the perfect, mirror opposite of Henderson's situation from a few years ago.

That must be why Henderson apparently didn't see any similarities between his own circumstances and those of Machida—hence his note that he has no respect for him.
