I recently discovered this website that carries EPO or Erythropoietin and I got interested in it I have heard that alot of bicyclists got caught doping or using Erythropoietin because it increases red blood cells. I have never taken EPO and was looking for some advice on what its benefits are and is a permanent increase in blood cells or are they increased while taking it and then go back to normal when you stop? Also, could it make my veins pop out more? Anyone ever try it and what was your experience? thanks
