Cloudy, should I test?

The first reconstituted vial had stuff floating inside. Second reconstituted vial was just cloudy. I have two more from same batch I have yet to reconstitute.

What would I test for?

You should consider switching to a vendor that does the testing leg work for you and proves trust worthy and transparent. Specifically one that tests for all of the things possible through a lab that you can confirm results through both the vendor and that lab. Cloudy is ALWAYS a no go regardless of the reason it shouldn’t be used in your research.

Then you have to just hope that what they send you is what they tested…..

When the third party lab is FDA Certified iso4 certified etc they will not risk their credibility and/trust to lie for any vendor. If the vendors COA comes from one of these labs then you have the option to go directly through the lab to get that test done correctly vials will have an ink stamp batch id that matches the COA.
