So you were suggesting members brew sub optimally ?

I am suggesting that if they are going to refilter their ugl gear, they should consider homebrewing. If they choose to, there is the minimum effort way and there is the optimal way.

Check your state laws. You are in a favorable location IIRC. 20g of AAS in a kit vs 500 to 1000 g for some home brewing. Big difference from legal risk standpoint.

You seem like a smart guy.
I have seen you on the HYB thread and like the feedback you have given there, regularly.
Do you refilter what you buy or not?

No homebrewer for personal use needs more than 50gr of 4-5 compounds for years worth of gear. If you get a kg you either dealing or you are a gear preper like me.

Order once a year or order once. I understand your point. I might be able to muster the balls to order once lol.

I think the “regularly” may be exaggerated, don’t you think ?
I have received grape seed from Hyb and mct from Ga (before Ga went downhill and increased prices)
Haven’t refiltered a single vial from either.
I check for floaters to the best of my abilities, if I was to find a floater in any ugl vial. It would go into the garbage and I would move onto a different vial that passed my personal inspection
Lucky I haven’t came across that yet.

You can always pay a little extra and get it domestic. Raws don't leak either

It was meant for most of the things you bought (orals and oils).
I should have written it like that.
Apologies.

How did this become a home brewing thread? We already have those. What filters do you all like to use to refilter and what's your method?

PTFE 0.22micron 33mm, 20ml syringes hand, 50ml for caulking gun

I am sure some people simply can't due to space, time or other constraints. Time not so much I am dedicating max 4h every 6 months or so from start to finish. But space or other reasons I do understand.
And that's ok. But if one can, he should absolutely give it a go. Having peace of mind for 10+ years is liberating on so many levels. Like having a fully stocked self sustained banker in your backyard. You may not truly needed ever but what if.... mental state

My girl would think I am cooking meth. She is already not super excited with all the pharmacy and chemistry lab stuff I have.

In your opinion, what are the commonly available reputable companies for syringe filters?I'm just kidding of course
But in my opinion. the very last line of defense, the final items used in quality control, should be medical grade products from trustworthy sources. Syringes, vials, filters.
Those Ultra Spec vials are so cheap, yet certified to all the USP/FDA standards applicable to vials. there's really no reason to use others. (unless you want even higher spec like Corning Valor Glass vials and WestPharma stoppers, a good idea for long term storage).
The FDA has already advised no one use Chinese made syringes and banned most.
Filters should be sourced from reputable specialist companies, and not unbranded generics from Temu, Alibaba, or even Amazon.

For oils?
Syringe Vent Filters Hydrophobic PTFE Autoclavable
Autoclavable hydrophobic PTFE syringe filters. Pore size: 0.2 μm. Diameter of 13mm/25mm/33mm with Luer lock. For venting and air filtration.
shop.cobetter.com
There are marginally better filters but at astronomical prices.
For Petides:
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.

The best in this category use the "Supor" PES membrane, like Pall Filters, or B Braun. They're much much more expensive ($4-5 each). I buy them at huge discounts from science gear surplus sellers (I live near a "research triangle"). Pall is the standard for compounding pharmacies. But Cobetter is 95% as good, and superior (less protein adhesion, faster flow) to many name brands, never mind generics.

Thanks. I don't know anything about these companies so wouldn't know the difference between "Cobetter" or random generic Chinese name. The price for Cobetter Is actually pretty good.For oils?

They're huge, and while a Chinese company, have offices all over the world and supply many pharma manufacturers and high tech companies. Very well established with an excellent reputation of over 20 years. All they focus on is filtration.
As you noticed, they offer terrific value, even compared to "no names".
