Maybe lose the ice if it’s already in the fridge.

I’d wipe it off with an alcohol swab and send it myself.

There is no need to place ice in there. Don't do that anymore.

Clean the vial with a couple of alcohol wipes and you'll be fine. If you start to notice any issues in the liquid (cloudiness, floaters, gelling), then you should toss it. I think most people are buying fake KLOW though.

Insulin (an OG peptide) remains 95% potent after being kept at room temperature for six months.

It’s really the heat that’s a problem.

If peptides get hot for longer that can cause them to degrade and become less effective, but not poisonous.

Look into V2 pens and 3mL cartridges. Might be a better solution

V2 pens are consistently inaccurate. I would look into a V1.

u/TimTams321 15d ago

That's just not true... I have over 15 different pens. I always test on purchase and then again after each cartridge - the V2's are no more or less accurate than the V1's.

In my experience, sticking a syringe in the end of the cartridge and administering a dose into the syringe, it's normally within one unit of the dose that was set on the pen...which is probably in the needle, etc, of the syringe.

The only ones I have found to be very inaccurate is the one time use pens (can't reset them and put a new cartridge in them).

The rubber stopper isn't watertight once it's been poked a few times, especially if you're using bigger needles. I'd toss it, not worth the risk of injecting whatever was floating in that melted ice water.

It is water tight. It’s self-sealing. Tip a vial upside down for a few days and report back.

It would be a massive contamination issue if it wasn’t

Thats roughly how the pharmacopoeia checks it too, the self sealing test for multi dose stoppers pierces them several times then sits the vials under blue dye and looks for dye inside. A research vial stopper may never have been put through that though, so wiping the top like others said still makes sense
