I'm pretty sure it's been available from China for many many years, they make underground gh so why not epo. It's possible that it has some effects apart from the obvious, such as antioxidant effects. A bodybuilder doesn't need or want an increase in crit but perhaps it helps in other ways, who knows.
From glancing at forum threads on it it requires a pretty dedicated admin protocol to achieve effects. It's not like one injection suddenly makes your blood into mud.
