Moving Compound Pharmacy Tirz Into a Pen?

[jafarrr61020]

I don't think I'm alone here in starting my peptide adventures with compound pharmacy glp-1 and going off-road into grey. Currently I'm experimenting with a couple grey peptides and have graduated to pens with those, but am working through my supply of compound pharmacy tirzepatide, which came already set up as liquid in 3ml and 5ml vials.

I can probably just move that liquid to pen vials, right? They're multi-dose vials already, meant to be used over several weeks. The only concern I am really feeling is that I've stayed on lower doses than I was prescribed so the vials aren't four week vials, more like 12, making me think twice about putting them in the pen vials whose sterility I'm a little suspect of.

What do y'all think? Overthinking it? Shouldn't risk it, just use syringes, why not? Something in between with a risk mitigator I haven't thought of?

TIA!

I'm in the camp of those not wanting more than 4 weeks worth of reconstituted product in a single vial. So if this situation was foisted upon me, I would take my 12 week vial and aliquot it into (3) 4 week vials, freeze two of them, use the first one, then thaw out the other two and use them as needed.

There's enough evidence that freezing GLP1's does not degrade them significantly. I've done it myself and haven't had any issues, they still work just fine. I don't know if aliquoting would work the same with pen cartridges (freezing them I mean), as I don't have personal experience with that. I'd probably try it though with just bac water to see if it works. That's just me.

Slightly overthinking it but everyone's risk tolerance is different.

I'm still working through the last of my Olympia tirzepatide vials with a BUD of 9/25. There are many many of us still using them and for very extended amounts of time since they are 75mg per vial. I put them in pen cartridges and don't even track how long they've been open at this point. I'm comfortable that the pen cartridges are sterile enough as they come in steam sterilization bags with an indicator.

You can keep things very clean and minimal exposure with a pen IMO. They sit in a case in the fridge. You take them out, swab with alcohol, screw on a fresh new pen needle, inject and then they go right back in the case. I don't see any reason to believe a vial would be better.

Pretty much depends on what you consider more sterile - the pen cartridge, or the vial. I would say the vial.

I've done it. I like using pens, and didn't want to use syringes just because I was using up my compound.

RIP Olympia. I ended up with 8 last July and August. Still have two. They started out strong AF. Will probably never use them now. Will save as a Relic and possibly frame. That was peak LumiMeds.

I still have one sealed vial and will probably not use it at this point but I'm hanging onto it for awhile longer. I loved that concentration. Now people are running into having to use multiple syringes because compounders are sending out 10 mg/ml for people on 12+ mg. Annoying. I'd go grey just to avoid that if I was still on tirz. I feel better on just reta though.
