A bombshell investigation by the Miami New Times into an anti-aging clinic in the city revealed several notable athletes as clients and strongly suggests that they were recipients of performance enhancing drugs.

One of those athletes is Yuriorkis Gamboa, the Cuban Olympic gold medalist who has gone on to capture two featherweight titles and an interim 130-pound belt in the pro ranks.

The Miami New Times article cites a notebook dating back to 2009 that the newspaper received from an employee of the now-closed clinic. In it, the article says, is a listing of the drugs Gamboa was allegedly receiving from Biogenesis and Anthony Bosch.

“In the 2009 notebook, Bosch outlines an extensive program he was shipping to Gamboa. In addition to protein powders and calcium/magnesium/zinc compounds, he included a six-day-a-week HGH regime, IGF-1, and a cream with 20 percent testosterone,” the article said.

“What's more, Bosch even notes that Gamboa's next bout is scheduled against Brandon Rios the following April and writes, ‘Start clean-up Dec. 1’ — presumably giving the boxer enough time to pass doping tests. (The fight against Rios was later canceled, but Gamboa won two other fights by TKO and KO that January and February.),” the article said.

[It should be noted that those Gamboa wins were actually in early 2009, not in 2012, when Gamboa-Rios would have been taking place.]

HGH is human growth hormone. IGF-1, according to the article, “stimulates insulin production and muscle growth.” It has been banned in sports such as baseball.

The 31-year-old Gamboa is 22-0 with 16 knockouts and last fought on Dec. 8, outpointing Michael Farenas on the undercard to Juan Manuel Marquez’s knockout of Manny Pacquiao.
