RCs Phenazepam solubility in propylene glycol

[RedBaron]

I am wondering what is the maximum phenazepam that would dissolve into propylene glycol? (as in what mg/ml could be achieved)
I tried searching, but couldn't find it, only a thread where someone made a 3mg/ml of phenazepam and propylene glycol solution.
And I am not good at chemistry myself to deduce from the chemical information for phenazepam and propylene glycol.
Anyone know the max solubility?

Try googlescholar I can't crawl through the studies at the moment. At least 5mg/ml almost positive though. This thread might help.

Ok, I'm shooting for 4mg/ml. Should work.
