Is that Hospira brand BAC, or the backwater kind?
DIY bacteriostatic water — does anyone here make their own?

Just so you know, Tirz and saline don’t mix well!

Easy isn't a word I'd use for it around here either. Two sites carry real Hospira, and each one charges roughly $70 AUD for a pair — that works out to about $48 USD. Paying $20 apiece feels like a bargain to me.
What most sellers offer is the [removed] or the [removed] product out of India. As far as I know, nobody has ever posted a solid third-party test on that.
The [removed] version is sketchy, and when one of the other well-known local [prempved] got tested, no Benzyl showed up in it.

There's no requirement for it. That said, it has a solid history and is a dependable source of BAC.
Generally speaking, other BAC options work just as well. And if a reconstitution goes wrong, BAC tends to get the blame. Unless you test, there's no way to tell whether the culprit was bad BAC, a bad peptide batch, or some other factor.

I keep hearing that plenty of folks mix up their own bac water.
I don't get why anyone would cut corners on BAC. It's the thing you inject more of than anything else. In the past, tests have failed on bac from vendors and from "Amazon". Hospira is regulated, pharma/human grade, and widely used. Without meaningful degradation, it holds up for 90 days.
Given how much you save with grey, why would you cheap out on bac? And DIYing it is nuts.
Saline is meant for single dose, not for mixing up something you plan to keep.
Always test your peptides, always filter, always use Hospira, or another pharma/human grade option based on where you live.

For this to work, did the water need to be made isotonic beforehand? From what I gather, that isn't relevant when it comes to irrigation or small subQ shots? I'm really interested in just how different homemade bac water is compared to the bac water I'd been getting from Amazon up until lately. My plan is to prepare a single vial and have it analyzed in a lab prior to using it. Honestly, I want to know how much endotoxin is present when you simply combine USP Benzyl Alcohol with Sterile WFI inside a sterile vial. In the USA at least, WFI isn't that hard to source.

Here in France I pick up 10ml vials of sterile water at pharmacies. To that I mix in 0.9% benzylic alcohol. I make only as much BAC water as I'll use right away for reconstitution. Whatever's left over gets thrown out.
Appreciate you getting back to me. After digging into it further, it seems the tonicity of Sterile WFI isn't really a big deal when you're only injecting small volumes. Actually, I found out that even standard bac water isn't isotonic. My plan is to put together a few vials and have one tested. Thanks once more.
About 12 months back, I started digging into making BAC at home. I came across a platform run by a university chemist, plus a few other spots where I could gather opinions. My own reasoning went like this: if the grey I purchase comes from a supplier I trust, and the testing results satisfy me, then there's no reason not to attempt my own mix. Whatever risk it carries, it surely isn't worse than the foreign compounds I'm already putting into my body, and I have more faith in how I handle things myself than in anyone else. The plan would be pharma-grade sterile water, then BA added into the sterile vial. BA isn't hard to source. Before prices jumped early last year, I picked up a flat of hospira BAC, though I still wanted to figure out the process in case I ever need it down the road. If it comes to that, I'll go with my own.

Yet another solid thread! This is something I've mulled over quite a bit, though I never actually dug into the details. In my mycology work I've produced plenty of sterile water, which got me thinking about whether I could do the same and then mix in BA. On top of that, I've got an entire case of Hospira BA water with a July 2013 expiration date. Would that still be usable, or should I just spike it with a bit more BA?

About sterile water: could you produce your own by boiling a pot of pure water with the lid flipped upside down to catch condensation? My guess is that what you collect would be sterile distilled water, and that it would be suitable for injection. One issue I've heard about is that pH may differ based on the point during cooling when you close up the distilled water.
For using it right away, I'd figure that's fine. However, if the plan is to mix it with a peptide that needs to stay good for a month, then you'd want 1 part BA per 100 parts water. The 99.995% pure USP grade BA from Revolve Chem ought to do the job without any problem, as far as I can tell.
Sure, grabbing Hospira is simpler, but sourcing it seems hard for some folks, and for those of us who can get it, I'm not convinced the supply will always be there.
Would this actually work? Anyone with more knowledge than me want to chime in?

Your idea has a lot of appeal, and as a hobby I actually fire up a still a few times every year — but if I'm being honest, I'd rather roll the dice on a 1-gallon jug of distilled water from WallyWorld than put my faith in what I cook up in the kitchen.
That's not me saying WW distilled is something to inject. My own route is Hospira through InjectionShop: once the order reaches $50, shipping costs nothing. Alternatively, following what Peter Magic suggests in that YT video, I've simply gone with Sterile for Injection. Either way, there are choices.

I share your doubt that the WW product would be sterile right when it comes out of the container. Still, I figure boiling and distilling it myself ought to wipe out microbes along with endotoxins.
Water labeled sterile for injections works fine, yet after you put it into a vial that has been punctured, there's no BA left to stop microbes from multiplying across the weeks ahead.
Either way, I doubt I'll go down this road--it's just a fun thing to talk about.

Getting BAC through a research supplier based in the EU or locally, one that includes a COA with its products, is the less painful route.
If you want something simpler still, pharma grade sterile water, saline, or PBS — the last being inexpensive and quite accessible — all come with few or no restrictions, and you'd just cap your vial at 30 days of use.
Like others have said, mixing up a 0.9% solution is theoretically straightforward, but proving it's actually "sterile" and free of contamination is a whole different matter.

When you distill water yourself, the tricky part is moving that water into sterile vials without airborne contamination creeping in. And what about endotoxin that lingers after distillation? Grok says reverse osmosis and other filtration techniques are what take endotoxin out.
My own method: purchase Sterile WFI (free of microbes and endotoxin), the kind hospitals use for IV bags. Get 10 sterile vials, then add sterile BA to each one, measured by mass. After that, move Sterile WFI into every vial with a sterile syringe, measured by volume. Everything goes through sterile syringes, so nothing is ever left sitting open to the air. Some air probably remains in the syringe, though there isn't much of a way around that, and ideally the amount is so tiny that the BA stops anything from growing.
Mixing the BAC water in front of a hepa filter, something people often use for mycology work, might cut the contamination risk even more. I'm tempted to give it a shot, but it takes far more effort than simply picking up Hospira

My approach would be to boil the empty vials together with their rubber stoppers in the water so that they get sterilized. After that, I'd pour the hot distilled water into the vials and put the caps on while everything is still hot.
As far as I know, endotoxins stay behind in the water that doesn't evaporate rather than being carried up with the distilled steam.
Sure, there might still be a chance that endotoxins end up in the unevaporated water that comes into contact with the vials, but even if that happened, the quantity would seem to be tiny.
