Thoughts on injection pens & peptide filtering?

[mercuryleaf7]

Hi everyone, I am currently waiting on my first grey order of Tirzepatide and whilst doing my research I have learnt about syringe filters and how they can remove bacteria and other nasties.

Obviously once you reconstitute and then go to pass the mixture through the filter you need a sterile vial.
I am struggling to find sterile vials or more so how to be sure they're sterile as I can't find any medical suppliers selling them in the UK.

I was thinking would it be better to just buy some pen cartridges and put the filtered solution into that to make it easier to inject each week.
I may have to sterilise the cartridges in a pressure cooker or something but I just thought if I'm going to all this effort anyway maybe I should have the convenience of a pen at the end of it.

Leading on from that what's everyone's favourite pen styles/brands? The ones I've seen so far are below.

• Injector pen v2/v3
• Bird pen
• Uni pen
• Novo Nordisk NovoPen4 (with adapter to make universal cartridges fit)

Ks-tek vials have been tested sterile and are available through Amazon or their website. I just checked and Ks-tek expanded their website to include cartridges and 4mm filters as well. Filters ordered in bulk are under $1ea!

Edit to remove "sterile" for cartridges. Seeking clarification from Ks-tek.

Omg that's great I'll have a look. Hopefully they ship to the UK.
Thank you 😊

I'm strongly considering a bird pen because it's hard to get my V1 to work one-handed. But I keep hearing whispers that auto-injectors don't work well with sterilized carts, and I am not going to screw with sterilizing my own in the instant pot where I cook garbanzo beans.

I did see people say they messed up the carts' rubber bits by doing that!

Yep--there is just nothing that can make me believe I can achieve a consistent level of sterility that way without hilarity ensuing. So I lurk on all the pen posts, waiting for someone to burst onto the scene and say "Hey, look, these sterile carts work great with the bird pen, and also, here's a place selling the bird pen for twenty dollars, and also randompersonrandom gets a pony!"

So I looked and noticed their cartridges do NOT say Sterile.
it says the packaging is sterile wth?
"Sterile Packaging: Each Cassette Bottle is individually packaged, providing you with a hygienic solution for insulin storage and safeguarding against contamination."

this is a concern.

The cartridges I use come sterilized.

This is the type of pen I use (I have 3 of them)

You could buy all your supplies from them and I think that they ship to the UK since I was able to change my shipping address to that .. but I of course didn't follow through. I would send them a message before ordering just to make sure.

underground supply also has them at a lower cost

If you search pens you'll find previous threads in which this has been discussed at length.
This is always the best way to get as much info as possible on this forum.
I am using V1 pens because I like that they: come in pretty colors, are covered by a closed cap, and they were very reasonable from Alibaba, but can be found on other websites here.

Thanks for pointing that out.

It used to say the same for their 3ml vials and Janoshik tested confirming sterility. I've emailed Ks-tek about the cartridges and will update if I hear back.

They do not ship to the UK. It looks like only the US and Puerto Rico.
