I have talked to many home brewers, and many reported very little effect from aas heated for sterilising pourposes.
Some "big" friends have tried home brewed stuff NOT HEATED, and they claim to be much more effective than the "heated" one.
I myself tryed some home made Cypio and Deca (heat sterilised, 30 min x 3), the Cypio had been analised and was legit, with no effect whatsoever...
I have made some deca 200mg/ml sterilising the oil (60 min 180 degress - I live in Europe ) and the vials (of course), 7% BA and 15% BB, filtering 0,44 and 0,2 and NO HEATING either the powder or the final solution.
I sent a sample to the microbiology lab where it was cultured: NO GROWTH.
They actually tested only aerobic bacteria.
There are few other microorganisms who could theoretically be in there:
anaerobic bacteria
virus
fungi
prions
spores
Anaerobic bacteria: I do not know how they could be in the stuff. They do not survive in air. The oil was sterile so it cannot contain anaerobs. The only contaminant could be the powder. BUT, powder was dry and exposed to air. Besides BA kills bacteria, yet I do not know if it kills all kind of anaerobs.
Virus: destroid by BA 7% (it should be enough with 1% actually)
Fungi: after some time they should "show" in the oil. I have had the stuff for 6 weeks now and it is still clear. Besides, I suspect the BA kills them.
Prions: are proteins which can transmit seriuos diseases like the mad cow one ... I do not know much about these. I wonder why they should be in the original raw powder, where they could come from ... and I do not know the effect of BA and filtering ... I suspect they being pretty much difficult to eliminate or denaturate without a proper heating cyclus, but I do not know ...
Spores: again ... why the hell should a raw powder contain spores? No idea whether BA destroys them ... spores which give bith to aerobic bacteria should have shown with the test, which was negative ...
As u see, there are fre unanswered issues, but I have the practical test by at least ten people who have been using the stuff since last spring and are alive and kicking ...
Just my two cents

PS - I have not still tried the last Deca ....
