I live my life as an N=1, he told Gizmodo, referencing research studies with just one subject.
In November, Greenfield visited U.S.
Stem Cell, a controversial clinic in Florida, to have his penis injected with his own stem cells.
In August 2017, the Food and Drug Administration sent U.S.
Stem Cell did not respond to repeated requests for comment.)
I wanted to go from good to great, and to get a bigger dick, he told Gizmodo.
Im not going to lie, thats why guys without erectile dysfunction would do this.
In the webinar, Greenfield and Comella explain how the procedure worked.
Stem Cell isolate stem cells from his bodys fat cells.
Then, said Greenfield, those stem cells were injected into the meat of the tissue of his penis.
Severalearly-stage studieshave shown that stem cells do show promise in treating erectile dysfunction in men.
The stem cells were injected at the base of their penis.
Greenfield, though, was seeking to enhance his manhood, rather than to fix any medical problem.
The evidence that such a treatment could help treat erectile troubles is still nascent.
Evidence that it could enhance a man without any such issues iseven more tenuous.
The body doesnt necessarily work that way.
Nonetheless, Greenfield said in the webinar that the procedure had made him noticeably better hung.
Three or four days after the procedure, he said, it was almost like it grew.
His erections were also bigger, his penis got harder, and his orgasms were better, he said.
Gizmodo asked Greenfield whether he had measured his change in size.
But he thinks it looks noticeably larger.
When inside of my wife, she can tell, he added.
Greenfield, who considers himself a biohacker, is a big believer in stem cells.
Hesalso injectedthem into his own arm as a performance enhancer at home.
There is still a risk, he said.
But the payoff in terms of health is very big.
You cant always wait for things to be thoroughly studied.
Stem cells do have lots oftherapeutic promise.
Some treatments, including some of those offered by U.S.
Stem Cell, seem to flout those rules, but so far the FDA has had difficulty cracking down.
That may change, with anew regulatory initiativeannounced last fall.
Its not normal, he said in the webinar.
I dont think ancient man injected stem cells, especially into his nether region.
Were fighting an uphill battle, he said.
