I've spent time reading up and researching the testing and filtration side of Gray products. There's no disagreement from me that we should verify the identity and quantity of what's in the vial. And yes, paying a little extra to filter seems like it's probably justified. That said, filtering itself introduces a chance of contamination that simply reconstituting a vial wouldn't. When you then add endotoxin screening on top of that, doing the whole thing properly turns into a fairly involved undertaking.

So my question is: do compounding pharmacies actually follow practices like these? Are they running filters? Are they screening for endotoxins? My assumption is that their product comes from manufacturers that FDA inspects, but it's also conceivable that certain gray suppliers are the very same ones. With that in mind, what do compounders actually do to make sure people are safe?
 
Dr Google covers it pretty thoroughly. Short version: testing happens in-house for some and through outside labs for others. Endotoxins, live bacteria and potency - the same things we chew over on this forum. Any batch failing those standards has to be destroyed.
 
Addendum - beyond that, their work happens in clean rooms governed by rigorous lab protocols. My setup is a different story: essentially the dining room table at home, plus a cookie sheet that's been hit with alcohol….
