Although manufactured for erectile dysfunction, Viagra was promoted last year for having benefits on pulmonary hypertension patients and this year a study shows that it may improve the athletic performance of mountain cyclists at high altitudes.

In order to finish a stage in racing the high Rocky Mountains, many of the cyclists are already taking illicit drugs to get them through the race which takes about an hour to finish. By using Viagra, the cyclist were able to finish the race in 39 minutes and improve their performance by 45%.

During the study, 10 cyclists got the pills, some Viagra some placebos. It was impossible for them to say whether they took the drug or not while they were cycling but it was surely obvious in the shower when the race was done.

The Viagra did not work on all the participants, it worked just on those were most affected by the high altitude to compete better.
