Heating raws?

[Purge]

Personally, I think filtering is enough. Endotoxins and pyrogens don't seem to be a major problem, based on anecdotes about PIP. You could further avoid them by using sterile pharm grade oil.

If I were a UGL, I might feel differently (and pre-heat the oil), just because the risks are greater if you're brewing liters per year, not 100 ml here and there.

sounds about right....no need for the .22 .45 filter has always worked fine with me ...also 100ml isnt using much powder at all ...id get a 500ml at least to use

As a lab founder I cant believe you dont think a .2 micron filter is necessary. I could understand if you were brewing for yourself, but your making a product others inject. At least your honest and members will see you take short cuts in your brewing process.
