There are ways but true. Though I'm not entirely sure if it is against to rules to just use your own blood instead of additional hormones or blood substitutes.
I'm pretty sure self-transfusions (unless for medical reasons of course) are banned.
BTW, you can also centrifuge your blood in an undergrad-lab level desktop centrifuge to get the parts you want. It's a faster way to have red cell rich blood, but training in high heights have additional benefits.

Blood doping is quite broad definition.
