Not looking to start a spit war about who does what, etc... Very good article for those interested in the subject from a good source.

A course of steroids combined with exercise can translate to a 38% increase in strength in men, potentially more in women. those taking human growth hormone saw their sprinting capacity increase by 4%. They can accomplish this through blood-cell transfusions or by taking EPO. In one study[url]2[/url], blood doping increased normal humans stamina by 34%, and in another[url]3[/url], it allowed them to run 8 kilometres on a treadmill 44 seconds faster than they could before. And work published last month[url]4[/url] by Max Gassmann and his colleagues at the University of Zurich in Switzerland, there are signs that the hormone has an effect on the brain, increasing an athletes motivation to train. Earnest estimates that athletes taking creatine could see their performance improve by as much as 8%. Another effective supplement is beetroot juice. Researchers at the University of Essex have found that the nitrate present in the juice increases nitric oxide levels in the body, allowing muscles to use oxygen more efficiently. As a result, the team found that divers could hold their breath for 11% longer than normal[url]5[/url], which could help swimmers who want to minimize the number of breaths they take in short-distance events.
Not terribly long be interesting if you want to get some more information about the effects of PED's. Also a pretty reliable site in terms of information integrity. Knew you would be interested.
