Test prop homebrew recipe

PES membrane is for sure NOT good resistant to BB,BA,EO . Nylon and PTFE are resistant to all solvents.
Flow depends on
- viscosity of carrier
- temperature of carrier
- vacuum power ( or press )
- type of membrane

ALCOHOLS PES membrane
Benzyl Alcohol, 100% NR - no resist.
Benzyl Alcohol, 3% LR - limited resist.
He is exchanging rate of flow for quality/sterility, way to go
 
I'm bumping this thread since I felt it gave me the most useful information of any thread here in relation to brewing prop and I hope this will be another useful addition.

Full disclosure: I didn't test my raws(from PPL) nor am I in a state where I can test my bloods. I feel similar to what I do on previous test(E) runs I have done, but I can't vouch for purity.

I was able to get what I consider an average PIP(mild soreness for 1-3 days) 150 mg/ml prop solution at 1/15 in a 50/50 grapeseed/EO mix. The brew holds no problem even in the fridge. I have issues with MCT and wanted something really thin since I pin with 27g or 30g needles cause I'm a bitch about that shit. I opened up a few new pin sites(quad/shoulder) on this cycle since it was my first time doing prop and needed to do so. That my contribute to the PIP. Fuck quad shots also.

I got the idea for my brew from another user here who was brewing prop 100 in a 1/10 BA/BB solution and I don't see why that wouldn't work either. Hopefully this helps with those out there that talk about high PIP with a prop 2/20 brew. I am rather new to the brew game in general but I feel the commonly touted numbers(for BB in general) are often a bit too far on the side of caution which can take things into "PIP from hell" territory.
 
Just a side note.....if you ever decide to brew fina pellets, don't use mct oil. It won't filter the binders out for shit! I might get 10cc's thru a 45 Whatman before it clogs up. That's after I run it thru a coffee filter. And it won't hardly drain thru a coffee filter either. Had to even keep changing the coffee filter out...Mct works flawlessly with everything else...

You brew using .45 filters?
