Primoteston Depot - Writing on amps

I'm wondering how it's possible to spot a fake Primoteston Depot amp?

I have Primoteston Depot's from 8 different lots, and the writing is different on some of the amps.

Should it be Primobolan_Depot or Primobolan - Depot on the amps for example?

Check the pics of the amps here:http://www.anabolicreview.com/vbulle...ad.php?t=84153
