If you're not too concerned about budget and just want the best, you should be looking at Pall brand filters, and specifically for peptides, ones using the "Supor" membrane, which is a superior type of PES filter.

The "Pharmassure" line is the ultimate, and the gold standard used by compounding pharmacies and big pharma researchers.

It's my preferred filter, the main advantage being a much higher flow rate and more accurate filtration (more precise holes in the membrane).

I buy them from a scientific surplus company that scoops up excess supplies from completed research projects. That said, from a safety standard, pretty much any brand will do what you need it to.

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.
Have a buddy that will reuse needles.. that shit bothered the hell outta him. I give him needles for free ( I have a 3-4 years supply)

I had an idiot buddy that said he would reuse needles too. I had to confirm he was doing exactly that and he told me yes he would reuse the same needles.

Fucking people man. Wtf.

Oooofff. You are not a cheap date. My goal is to be Ghoul type of rich. The quantity isn’t specified, but if I’m mathing right, the PES ones are 50/pkg for $167.

I spent my childhood in ill fitting yard sale clothes and being the "second shopper" at the grocery store to get around "1 per customer" discount limits.

What was a kind of humiliating experience as a kid turned out to be good preparation for later, when I discovered that, while my wealthy employers/mentors appeared to spend extravagantly, behind closed doors valued and practiced the art of "squeezing a dollar out of a quarter" on every purchase they made.

Try your luck on ebay:
