I am a lifelong endurance athlete (running, triathlon and bike racing). I tried my first cycle of EPO. Diving into the world of endurance gains and blood doping I was under the impression that taking that drug you would see serious noticeable gains in performance. A lot of studies show that your time to exhaustion and V02 max go up between 5%-10%+. Some studies are inconclusive. With that said reading tons of material on professional cycling in the 90's-2000's when EPO was first abused by the peloton; a lot of the pros talk about once it was introduced the speed of the peloton went up so steeply that if you were not taking the drug you could barely hold on in races. Also accounts of heavier sprinters (usually heavier and have trouble getting over mountain stages in multi day tours like the TDF etc..) who normally could barely get over mountains in grand tours, were winning mountain stages. Everyone's favorite doper Lance Armstrong said EPO was "rocket fuel" and "minimum provided 10% gains."...So naturally when I took the drug I thought that I would notice serious performance improvement. I got my hematocrit up to around 52.3 and my hemoglobin around 17.1 (from a base of around 44 and 15ish). While I have seen my power increase on the bicycle it is so subtle it is hard to tell if it is just from hard structured training or the drug itself. I guess what I am getting at is my experience is that the gains are underwhelming. Maybe that is just the way it goes with different physiologies or perhaps I have not jacked my blood values high enough into the more dangerous territories to see a difference. I know there are not a lot of endurance athletes on these threads (let along endurance athletes who have cycled EPO) but would love to hear anyone's experience or insight.
