A Russian scientist who injected himself with a bacteria that he believes is the key to eternal youth, as previously reported by HNGN, claims that he now feels stronger, according to the Telegraph.

Anatoli Brouchkov, a scientist at Moscow State University, injected himself with Bacillus F., a bacteria that has been able to remain alive in permafrost for approximately 3.5 million years, leading him to believe that it harbors some sort of secret to longevity.

"We have to work out how this bacteria prevents aging," said Brouchkov. "I think that is the way this science should develop. What is keeping that mechanism alive? And how can we use it for our own benefits?"

Although Brouchkov has test the bacteria on mice and human blood cells, this is the first time that he has tested it on a live human subject.

"I started to work longer, I've never had a flu for the last two years," he said. "After successful experiments on mice and fruit flies, I thought it would be interesting to try the inactivated bacterial culture."

Brouchkov admits that his lack of sickness is likely not solely the result of his injection with the bacteria, but he hopes to use the bacteria in an upcoming clinical trail to narrow down its specific beneficial effects, according to the New York Post.

"It wasn't quite a scientific experiment, so I cannot professionally describe the effects," he said. "But it was quite clear for me that I did not catch flu for two years.  Perhaps there were some side effects, but there should be some special medical equipment to spot them. Of course, such experiments need to be conducted in clinic, with the special equipment and statistics."

The Bacillus F. bacteria was discovered back in 2009 at Mammoth Mountain, and thus far has been shown to allow older female mice to reproduce, although its mechanism of action is still not known, according to The Siberian Times.
