Thread: where can i get sterilized GSO

You can make it yourself by running it through a sterile filter.
Or if your using it to make gear it will be sterilized when you filter it.

Researchsupply has it but brundels idea is better.

Sorry, I have been lazy lately.


Often people pay an arm and a leg for filtered oil. Somewhere in the realm of 17$ for

100ml.This is insane as its very cheap to buy. You can buy a couple liters of safflower oil

or grapeseed oil from your local grocery store and filter it yourself.

Lets start with 1000ml just to get the idea.
You will need:
1000ml, your oil of choice
1x Millipore 22um stericup filter and receiver cup combo. * You will also need a hand pump
1x septa top



1. Setup your filter by attaching pump and filling the top with 1000ml oil.
2. Give the pump a few squeezes untill the PSI guage reades 8.5-9 (no higher).
3. Every few min squeeze a few more times to keep pressure at 8.5-9 PSI.
4. When all the oil has been filtered carefully remove septa top from packaging and carefully replace the filter on top of the receiver with the septa top being careful not to infect the bottle.
The septa top has a silicon stopper that allows a needle to pass through and you to draw oil from it in smaller than 1000ml increments.
You can add 10ml of BA if you want but there is not really any need unless you plan on injecting the oil straight from the flask. For example, you are cutting a bottle of prop shot by shot. (not recommended)
Usually you will be filtering the oil again so the BA can be added then.
I say 10 ml BA so that you can add another 10ml when preparing an injectable =2%
You can usually run 3000 ml easy through a filter and even more if you use a prefilter.
There is usually not a reason to produce more than 1k sterile oil at a time.
No you do not need to heat it. A 22um pore filter wont let anything through. It shouldnt take more than 2-5 min.

Good luck

^^ beat me to it...

supermarket/grocery store and do what brundel just said

Brundel is my hero

southern research company is where I got mine. I thought it was decently priced
