Default How to know my chip a MUSES 8920 op.amp is fake or not

I have bought a Muses 8920 , i do not sure it original.
Because i tried and compare with another chip, not good and ordinary such as jrc 5532dd. I said poor.
I feel this is fake but seller said original.
How to know ?
Regards
Ed

Does Muses provide pictures which show what one of their 8920 opamps looks like? Other than that you can test for supply current - does that match the datasheet specification?

Wire it into a breadboard and check gain/bandwidth is correct.
