So if you take your Chinese generic GH and you shake it vigorously after reconstitution and it becomes cloudy then what you have is legit GH???
I know that's not what you're saying. Maybe this is a way to disqualify bunk GH but certainly not a way to quantify legit GH.
If the Chinese can reproduce the sides of GH I'm sure they can figure out a way to make a lyophilized powder cloudy upon violent reconstitution.
