Filtering question, My Sister is a Nurse, we were talking peptides and stuff I have never used a filter but after seeing a lot of talk on here about them. I asked her if she uses them, she said no you don't need them. She said they were / are used to make sure no glass gets in due to the vials that you have to break to use. That is what the filters were for...??? She also speculated that they could hurt the peptide by forcing it through in other words being ruff with the peptide like as in you are not supposed to shake the bottles also said it has nothing to do with sterilizing. So I am asking Is her info out of date or just wrong or what?

I would say in a nicer way that gray market peptides are outside the norm for most medical professionals. Though she isn't completely off about shaking , some stuff is more robust (tirz), other peps won't do well with shaking which is why it isn't recommended on any starter guides on reconstitution.

Filters are often used in lab environments. If you start looking into it you will quickly find that there are many different filter materials used for all sorts of different chemicals. You will see that for the majority of peptides we use .22um (pore size) made of PES, size depends on amount though 13mm and 4mm being the most common. PES is hydrophilic and lets almost all proteins on through which is why we use them.

Hopefully someone will show the cool graphic about pore size compared to microscopic things that get filtered (and won't get filtered). I should have saved it for just such an occasion.

Ok, what I am getting is that they make filters for bacteria and using Gray it's a good idea to filter for it. ??

They make syringe filters of different sizes,pore sizes and materials. They are not specific to bacteria.

As far as it being a good idea? Maybe? In a vaccuum , yes its an added process that should improve the safety of the product. In the real world it isn't that cut and dry.

Every additionally step that filtering entails is another vector where you are potentially making things worse not better. That isn't an opinion just probability.

I will say if you are using a pen and cartridges there is almost zero reason not to filter.

Here is the image (thanks @Grogu ) that I was referencing earlier;
