The company I'm getting my oil from offers USP Grapeseed oil and the same oil that they filtered through a .22 micron filter. The filtered version is over 3x more expensive than the non-filtered version.
Would it be okay for me to prepare my injectable solution with the USP Grapeseed oil that hasn't been filtered, heat it like normal (which should sterilize it itself) and then filter the prepared solution through my own .22 micron filter?
I read somewhere that sterilizing oil for injections requires many steps that also involve removing some of the oil. Here's what I read on a different forum:
Would these steps be necessary for the non-filtered USP oil, or can I just do what I described above? Or... would it be best to just get their filtered USP oil and do my original plan (prep & filter)?
Thanks!

I read somewhere that sterilizing oil for injections requires many steps that also involve removing some of the oil. Here's what I read on a different forum:
1. Allow oil to sit undisturbed for 7 to 10 days.
2. Using a sterile 20cc irrigation syringe decant the top 1/3 of oil.
3. Place oil into pyrex container and heat to 275 degrees for 45 mins.
4. Place oil into testtubes and centrifuge at 1500 rpm for 10 mins.
5. Decant all but the last 3ml or so from the centrifuge containers into sterile vial.
6. Use in preparation of injectable product.
