I'm not sure, but I think you mean Han Seo's anadrol 50, which is in korea, not china.
I can't tell you how it compares with anapolon, but it's what I am currently using now. Seems quite effective (gained 20+lbs in a matter of weeks). I haven't retained much water at all, which is a big suprise to me, but a welcome one at that
Sides seem usual with all other forms of anadrol, high blood pressure, and an increase in my pulse.
