That said, what's the real state of UGL's and why. Get on board for the ride.
One minute this UGL is "g2g", the next they are the devil.
This problem seems to be twofold:
1. Materials
2. Procedures
The self-imposed radical secrecy surrounding powder sources doesn't help. #1. If people and UGL's had multiple sources - the bad ones would fade away in favor of the better vetted sources.
Onto the questions you should ask of yourself and your choice of lab.
Is your choice of UGL doing an continuous check on it's source materials?
Do the compensate the dosing based on analysis?
Are the rest of their materials USP/NF or AR grade?
(Sorry - supermarket oil doesn't cut it).
Do they even know why they are using BA and BB?
Do they know of the other options such as chlorobutanol?
Are they using aseptic procedure and sterilizing everything with heat and time in either dry ovens or autoclaves? Not "chemical" sterilization or "baking fluids".
Do they use 0.2 um membrane filters to purify the vial-ready mixed oils?
If they use a pump like a Dispensette, is it sterilized before use and is the makeup air also sterilized? (the pressure-equalization air can be filtered using one of those small whatman filters and an adapter)
Are the Vials stoppered IMMEDIATELY after filling? In a sterile manner?
Are the crimps solid and the vials/stoppers/crimp rings of adequate quality
These are the questions that need to be asked.
It would be optimal if the lab submitted random samples of finished product for biological contamination testing as well. Not sure if that's even possible on a large scale, though.
Can your UGL lie about these things? Sure.
But enough people asking enough questions,,, and...
The truth shall set you free.
Just a short ride, but we can go on a long one it needed. As I've always stated. AnalogMan does not "promote' anyone's products. I don't need "free" stuff.. I have enough . So, I'll keep it "real".. That's a promise.....AnalogMan
