Really need help-If Peptide Vendors Can’t Be Trusted for Sterility, Why Trust the Filters?

[Eleanor]

Where can I find vent needles for a decent price? I thought of using just regular 1ml syringe, pulling out plunger and seeing if that worked. No expense burning those Comfort syringes. Anybody w/opinion?

Thank you!

@Eleanor, I use a 31-ga insulin syringe with the plunger removed; never had an issue. Sometimes I use a luer-lock needle, but I don't have many of them around anymore.

@Chuxpeps Thank you so much! I have plenty of the 1ml and the physics made sense, so I don't want to buy anything I don't have to buy. Muchas gracias!

Biologix USA sells PES fillers. I learned that Hydrophilic PVDF filters are better because they stop less of the peptide material than PES.

@Eleanor i just use regular lurelock 32ga needles from Amazon. They are super cheap for a box of 100. I bend the vent needle by 20 degrees so the plastic part is out of the way while I fill my pen vial.

@vpeptides Either that, or as Our Host does, push some extra bac into it to clear it.
@theckman80 That's a good idea too. Either way I go, I'm going to have to bend the needle.

You can also just add a small air bubble at the topmof you syringe full of peptide and push the last of the peptide through with air.

In the end your needed safety level is a personal thing. You can go down the rabbit hole and find possibilities for problems everywhere. You may fall at the level where gray peps just don't make sense to you. I have friend that doesn't test anything and just pins. I am more in the middle. I filter, have tests done on batches, and do what I can do minimize the chances, but know the risks.

Also, there are sources for the filters that can be confirmed legit, you just won't find them on Amazon.
