I was one of them.
You need to reconstitute with WFI (water for injections) basically sterile water, and you should be good for 4 weeks, you can do 1 part WFI and 2 parts BAC, but reconstitute first with the WFI and once its completely dissolved add the BAC.
If you have already mixed BAC and it's cloudy, then you'll need to add WFI and it will clear over night
I suspect the PH,
We contacted the factory and they recommend Acetic Acid 0.6% and not BAC, I have some arriving today and will test it in a vial.
But TBH sterile water is just fine if you use it within 4weeks max
No DAC,
Just to be clear it does not effect the quality, what's happening is that the peptides are clumping together, when you add WFI (sterile water) you are increasing the PH and they then disperse and the vial goes clear
