At my rate, I figure I'll use somewhere around 4ml, maybe 5ml, of Hospira BAC each month. Has anyone here stretched a 30ml vial across 6 mos? Or am I overthinking this whole thing?

I’ve finally used up a vial that I first punctured back in August.

Wait, seriously!? That's great news. Once you punctured it the first time, what did you do for storage?

The way to pull this off is turning yourself into a total lab rat and pinning at minimum 6 peptides. That makes the BAC run out quicker.
Every vial I've had, I've kept using right through to the end. A few empty out quicker than the rest, but if it's handled and kept properly, a 6-month stretch wouldn't worry me.
that's just my take...
- wiped down both before and after use
- kept away from the toilet, never used or stored there
- put away somewhere cool and dark (a cupboard)
that's just my take...

Seriously, you're not wrong at all. I originally showed up for the tirz, yet now I've got a reta order in the works, plus I keep spotting all sorts of other stuff I could inject into a lab rat

I've got a vial of bac water sitting around that I opened more than 2 years back, and I'm still drawing from it.
Water doesn't go bad, and neither does alcohol — no expiration, no breakdown. Not within my lifetime, at least.
Bacteria? Not a concern for me. I keep the vial clean and don't introduce anything into it. And suppose I did slip up — that's exactly why benzyl alcohol is mixed into the water in the first place.

That reasoning seems sound to me. Still, since I'm quite inexperienced with all of this, I figured I should check. Getting that input is a huge relief. Thanks.
So far, nobody has given me a solid reason not to freeze, thaw, then freeze again a bac vial that's already been opened.
On top of that, when it comes to tirzepatide (though this doesn't apply to other peptides), I'm fine with mixing up several vials in one go and sticking the extra reconstituted ones in the freezer.
Your mileage may vary. Do whatever feels right for you.

Would you take the same approach with reta?

Nope, reconstituted Reta should never go in the freezer—keep it in the fridge. As for me, I keep using my BAC until the vial is empty.

Keep in mind the parenthetical (but not other peptides) — that distinction matters. Tirzepatide gets nicknamed the cockroach of peptides because of how tough it is, so to speak. Situations that would heavily break down other peptides are ones Tirzepatide basically brushes aside. I don't know reta very well, but freezing it would give me pause; my guess is its effectiveness would drop sharply, maybe even be completely destroyed.

When I was dividing up R50, I did. Nothing to worry about. I don't know of any testing on it, but several others have done the same without problems. Since I increased my dose, it no longer makes sense, though back in my early Reta phase it worked well for me.
I keep my hospita bac in the fridge too — again, the common wisdom says that's a no no. Given that I live somewhere hot, it's a reasonable choice for me.
And similar to zipper, I'll keep using a 30ml bac until it's finished, unless I notice an issue with it or with my peps.

Alright, where does everyone stand on sticking BAC in the fridge once it's been opened? Yay or nay?
Tests were run by the group to see what freeze/thaw cycles do over time to peps that have been reconstituted (one test covered tirz plus a couple of others; reta was in a separate test). With tirz, mass barely dropped at all, whereas reta showed a small decrease ... likely more than you'd want if it meant giving up the effects you'd otherwise get.
What hasn't been addressed is sterility and endotoxins, since those weren't part of the testing. People speculate about alcohol separating (possibly irreversibly) because of freezing, and about the vial seal being damaged by freezing. I'm not convinced.
Don't expect everyone here to agree on anything ... you have to settle on what you're comfortable with and accept your own risks. That holds even when you're weighing Big Pharma or a surgical option with your board-certified MD.

Mine goes back into the cabinet. I used to advise against keeping them in the fridge on the vials, but after checking a few just now, I didn't spot it.
I have a faint recollection that someone ran tests on this, and I'll need to track them down. Certain bacteria were harder for BAC to keep in check as the temperature dropped.
That's what led me to stop putting it in the fridge. If I come across it, I'll share it here.
Recently I came across some BAC testing results — unfortunately I can't provide a link. According to what I saw, BAC remains stable for 90 days once it's been opened.
As for how I keep mine: it sits at room temperature the whole time, both before and after the first puncture.
