I just celebrated my 40th birthday, and I'm thinking I need to take my running performance to the next level. I've been doing everything that letsrun posters recommend. I been logging lots of miles, doing my threshold runs, training in flats, and no matter what I can't get my 5k pr below 17 minutes. I don't have any kids, and I divorced my wife five years ago, so I have some cash in the bank. I really want to step up to the next level and have a shot at getting some decent PRs before its too late -- I'm hoping to run mid 14s or so. This is my question: where can I get some EPO and how can I use it in a way that's not going to harm me. I'd like some serious advice here from people in the know. I'm through clowning around.
