Only that it was a dense heavy smoke and would couch lock you and it grew big dense chunky collars .Amsterdam Amnesia is a version of Amnesia Haze. I got some seeds of it not long ago, but I haven't run it yet.
Anything else you can tell us about Amsterdam?
Maybe someone can narrow it down, or knows a similar strain.
Other than that I couldn't really tell you anymore, I only saw it once in the early 90's
