DIY bac water - am I nuts?

Okay, so I'm probably gonna get yelled at for this, but I'm hoping someone can at least learn from my mistakes... or tell me I'm not completely insane. I'm located in Europe and getting bacteriostatic water is nearly impossible without some serious paperwork and a business license. Buying it from shady online sources sketched me out, so I tried to make my own.

Here's what I used:

* Sterile water (NOT distilled, look for "for irrigation" or "for respiratory therapy") - bought online from a pharmacy
* Benzyl alcohol - snagged from an auction site

Tools:

* Sterile 10ml vials
* 10ml syringes
* 1ml syringes
* 0.2 micron syringe filters
* pH test strips (optional)

Basically, I filtered the benzyl alcohol, then mixed 0.09ml of it with 9.9ml of the sterile water in a fresh vial. Tossed the leftover sterile water after (since it's now contaminated). I've been using it for about a month, and so far, so good – no stinging or anything. But yeah, tell me how dumb this is lol.
 
FYI; medical-and-lab-supplies .com has USP/NF grade benzyl alcohol in 50ml vials (stopper included) for under $6, expiring late 2026. Enough to make over 5 liters of 0.9% BAC. They also sell sterile evacuated 10ml vials, but those expire earlier, like spring 2026. They don’t state the exp dates upfront, so it’s a gamble.

Some notes on that benzyl alcohol:

* It turns into benzaldehyde when exposed to air. Try not to inject air into the vial when extracting.
* Avoid polystyrene syringes for pure benzyl alcohol, use glass instead. I sterilize with a small autoclave.
* It's pH neutral (7).

I actually use it to make 1.8% BAC. Lots of multi-use vials have 2% benzyl. I add 27 units into a fresh 0.9% bottle. Hallandale Pharmacy wouldn’t tell me the exact amount they use, claimed it was a trade secret. Olympia Pharmaceuticls lists 2%, maybe because they're a 503B? Most 2% benzyl stuff is in glass, not plastic, vials.

Pfizer's 0.9% benzyl comes in plastic, but their 1.1% is in glass. I just transfer everything to sterile glass.
 
I've heard some... questionable things about non-brand-name BAC causing stinging and reactions. All anecdotal, of course. And unlike peptides, I haven't seen any independent testing of the Chinese-sourced stuff.
 
Pharmaceutical-grade BAC has been easily accessible since this whole panic started. Sure, the price is a bit higher, but it's still around.

I don't get why people are doing all this DIY chemistry when a quick search will find you places to buy it (this doesn't apply to those outside the US/Canada who have sourcing issues).
 
Yeah, all the sources I've found (in the UK) seem to be counterfeit. Didn't know the reputable brands until all this blew up.
 
For anyone outside the US/Canada, Birth Supplies Canada (midwiferysupplies.ca) ships proper bac water internationally, and it's not too pricey! They're often out of stock, so you might need to wait a bit.
 
It depends on the dosage you want. If you add 7.5mL of BAC to 15mg, then 0.05mL equals 100mcg.

I've been reading up on reconstitution. What volume of BAC water are you supposed to use, generally? Like, if you have a 15mg vial, how much do you add to get a reasonable dose?

It can be tough to accurately measure such small doses with a standard syringe, but you can dilute it further if you want bigger volumes for the same dose.
 
I find it easier to mix with more water, especially with small doses.

100mcg is barely anything on some syringes. I like to dilute more and draw a bigger volume, easier to be accurate.
 
Label maker—I mark the kit boxes with peptide and mg, then add mass and purity from the CoA and adjust dosing if needed. When I take vials out I label them because age-induced memory issues. Labeled vials get tested if dosing matters. Keep kits in bigger opaque boxes in the freezer.
 
true. nobody's posting before/afters with just peptides alone and expecting people to believe it. even with the fat loss the scale sometimes sits flat which makes it hard to say what actually moved the needle.
 
Ask smart questions. Don't ask and you stay dumb. Your 30mg vial isn't actually 30mg—batch testing shows what's really there, sometimes plus 30%. Don't think in concentration; it only matters for compounding pharmacies. Figure out how many units you want per shot, then calculate backwards on dilution. Skip the math—use the reverse calculator.
