Sterile filters are always individually packaged.
This is another decent brand, and you should pick yourself up some 13mm .22um PES filters for your peptides. Not just for particulates, but to reduce the number of aggregates to prevent immunogenicity and minimize the risk of, god forbid, hitting the "peptide horror lottery" of a self replicating misfolded protein from lodging in your brain and saddling your relatives with a drooling version of yourself with a destroyed mind.

I have read someone say that you can run a little BA through a filter and sterilize them... but i have no idea if that would work. However why.. i mean i try and be frugal myself but we are talking about one of the most important factors tors of gear...(sterility) so spare no expense in that department is my opinion..

Seriously asking, does it truly matter if the syringe filter itself is sterile?
On one end of the filter you connect it to the syringe tip containing non-sterile fluid.
On the other end you have a sterile needle poking into the vial's rubber stopper.
So long as the fluid goes through the filter and into the needle wouldn't it be guaranteed that everything flowing in the vial is sterile?
I have never used a syringe filter so IDK.
I grabbed 5 of these. Pricey but I will shop around more next time. This site sells out a lotSterile filters are always individually packaged.

Thanks, I actually have the pekybio filters for the primo. Don’t remember what brand I got for the HGH, but they are sterile. Forgot why I decided not to get cobetter, but might get some next go around.Sterile filters are always individually packaged.

I wonder how their bottle top filters compare to millipore.Sterile filters are always individually packaged.

A compounding pharmacy once had an injectable product they produced lead to the deaths of numerous people because it was determined a mold that developed on a pile of rotting leaves outside got into the ventilation system and deposited a few spores at essentially undetectable levels into a few vials within their "sterile processing area".
Unsterile filters are not produced in a way that focuses any concern whatsoever about what they may impart into what they're filtering because they're not expected to be used in processing anything that will be injected into a living creature.
I will say that if you are just filtering smaller amounts.. like a kit is make sure and get the 25mm diameter.. the 33 would be rate to filter a larger volume but it will hold more of you product.. I mean you can clear it out with pushing air thought it. Ut I don't lije doing that

The oil, syringe, and needle should always be sterile (if your goal is harm reduction). Ditto with the bac water you use for peps. You’re injecting this stuff into yourself after all. Unless you’re the reusing needles kinda guy, in which case just use tap water, olive oil, and send it.

They offer sterile and unsterile filters. I was linking to the site, not the specific product.
Sterile 0.2 μm PES Syringe Filters
Hydrophilic PES syringe filters with single or double-layer membrane. Pore sizes of 0.2μm. Diameter of 13mm/25mm/33mm with Luer lock. Sterile individually packed. Used for sterile filtration of protein solutions, cell culture media, and buffers.

Suggest foregoing the prefilter version, it's unnecessary and likely wastes some peptide.
The filter is what does the sterilization.. so if you ard filtering with a non steril vial the only thing you are doing is catching debris.. not sterilization
Oh I looked at there site and did not see the sterile optio... imma look again!! I looked again and the only ly sterile options for the syringe filters are in pes and pvdf

For the primo, I use 25mm because I dilute with MCT. I might have just one vial, but I divide that into 5 vials and between filtering the primo and USP MCT, I think I need the 25mm.

Best deal I've found for sterile.
