Methandienone/Bionabol

Hi,
Can anyone tell me the difference between Methandrostenolone (Dianabol) and Methandienone (Bionabol)?
The first I can come up is that the difference lies in the manufacturer, say Methandrostenolone is made in Gr. Brittain and Methandienone comes from the Balkans.
But is this the only difference?
I have also read that the 5 mg tabs of bionabol contain 4.8 mg of Bionabol, but I could not find this on Dianabol.
So…anyone??

I have seen dbal with Methandrostenolone and Methandienone.

I don’t know the exact difference, and I can’t tell the difference when taking either one.

You probably won’t either.
