A noble pursuit, a fool’s errand, or just an example of men at their worst?

Ben Greenfield, a self-described biohacker in the United States, claims he’s increased the size of his penis by injecting it with stem cells.

“I wanted to go from good to great, and to get a bigger dick,” he said in an interview with Gizmodo. “I’m not going to lie, that’s why guys without erectile dysfunction would do this.”

Questionable procedure? Questionable clinic?

Greenfield underwent the procedure at U.S. Stem Cell, a clinic in Florida with a reportedly questionable reputation and poor track record.

In 2017, the clinic unintentionally blinded three patients undergoing controversial stem cell treatments, U.S. Stem Cell then received an official warning letter from the Food and Drug Administration.

In part, it read: “marketing stem cell products without FDA approval and for significant deviations from current good manufacturing practice requirements, including some that could impact the sterility of their products, putting patients at risk.”

But this didn’t stop Greenfield from going to the clinic to receive his injection. In fact, as Gizmodo pointed out, Kristin Comella, U.S. Stem Cell’s chief scientific officer, appeared with Greenfield in a webinar in February praising the procedure, which involved extracting stem cells from Greenfield’s fatty tissues and then injecting them into his penis.

Has the operation been a success? Well, according to Greenfield, yes. However, he’s used a less-than-scientific form of measurement: “When inside of my wife, she can tell,” he told Gizmodo.
