I get my Sust in a 10ml multidose bottle, made here in a local lab (HOMEBREW).
It's very good shit, now my question, is that I picked up my next couple bottles and the oil is a darker color then the first batch that was made.
I'm told it's good and tested I just wanted to confirm that the oil color isn't that important (incidently I DO trust this lab). It looks and feels to be the same consistancy in the syringe etc ... just looks to be a darker yellow
