That's what real life tells us: pharma aas are more expensive for that exact reason.
Years of experience has taught me that people lie for financial gain when there is a low chance for consequences. There are more fake/underdosed gear than fake wholesale coke for a reason
What I didn't really know is what Zebedee and SpacemanSpiff have been saying about sterility.
I thought each batch could be tested for it and its sterility guaranteed.
But they said that the many stages of the production process do not allow for this to happen and for confirming that the tested batch is sterile, in its entirety.
So, this would make the sterility test useless.
I wrongly assumed otherwise (well, ignorance).
Aside from hplc testing of the raws, you also think anything else is irrelevant.
If sterility cannot be confirmed, the same would go for endotoxins, if the two things can be related in the way contamination can happen.
We go back to purity (+ concentration for finished products) being the only test of interest, as far as ugl and home brewers are concerned.
Anything else, cannot be tested in a way that is reliable, because of the way it is produced.
= enhanced testing and more expensive lines for ugl are a waste of resources
