NOTE: Has a little bite during injection, barely noticeable. Small amount of pip, negligible.
My process:

I added powder to beaker.
Added BB and stirred. Let sit 10 minutes then stirred again.
Added all MCT oil room temp.
Stirred and let sit 1 hour.
Stirred again and added to hotplate(old rice cooker)
Left on warm setting contantly stirring until brought up to 130F.
Take off hotplate and continue to stir until temp dropped to 110F.
Put back on hotplate to 130F once again, stirring whole time.
Remove from heat, add BA.
Stir until temp drops to 105F.(depends on your filter)
Filter by pumping to 10in/Hg.
As it filters slowly drops vacuum to 5in/Hg.
Repump to 10in/Hg.
Filtering took about 15 minutes.
To get out most of remaining oil, pump to 10in/Hg..
Walk away, it will slowly lose all vacuum. Repump.
Do this a couple times.
Some will go to the gods. Maybe 1/2ml. (greedy bastards)
Remove bottle top filter.
Place lid on media bottle.
This next part may seem sketchy, but it's fine.
I have a big Honeywell air purifier I have running in the bathroom prior. Everything is wiped down. No rugs, hardwood floor.
The purifier if off during brewing and transfer.
I wear these gym clothes that are silky, so less chance of fibers coming off clothes.
I take a 60ml syringe, put on 20G 1"needle...pull plunger back ready to remove. Unscrew cap to where it is just sitting on top of media bottle. I hold syringe with outsteetched arms and pull out plunger, remove lid from media bottle and pour/backfill 60ml syringe, put lid back on media bottle, put plunger in syringe slightly, then hold syringe needle up so air is at top and push plunger all the way in to seat it.
I use 24G needle to vent sterile sealed vials that were swabbed.
I then dispense into sealed sterile vials.
Now, I need to refill syringe.
There will be slight amount of drops lost from needle drippage.
I inspect my vials with light and have never seen any contamination such as body hair or skin, other(I shave my head bald and trim body hair regularly).
I fill the bathtub up with many bottles of Nair Hair Removal, put tape on my eyebrows, and lay in the tub fully submerged and breathe with a snorkeling tube...jk bro lol.
We are talking about 3 seconds where the oil meets outside air into syringe. Yes, not most sanitary because I am not wearing a full body suit used to capture ET and his pals.
Now some will say, and they are correct.. no need to go that high in temp.
It's fine, melting point is far far higher.
I do know some who "cold brew" by letting sit over night, while BB does all the work... and adding small amount of heat around 98F (body temp) for final stirring/mixing.
