Everyone claims the usual bacteriostatic option sets the benchmark yet finding any here in the uk turns out nearly impossible so i'm wondering what others make of this version. The acidity level sits at five point seven matching it exactly. This ten milliliter bacteriostatic mixing solution comes as a sterile non pyrogenic liquid meant for laboratory research work. It includes zero point nine percent benzyl alcohol at nine milligrams per milliliter serving as a preservative to keep quality intact across repeated draws in ongoing studies with key details covering precise volume.

I could always buy some clean water made for shots at the drug store and add benzyl alcohol to it.

I picked up the factory-prepared version or put something together on my own. Hard to believe the situation remains unchanged.

Assuming the supply issue with that product lasts into the following year, personally I see no problem switching to sterile water designed for injections. Everyone might be complicating the matter unnecessarily. I'll attempt to secure orders for it several months early, however it won't cause me any worry. Nevertheless, I'd stay away from purchases via online marketplaces or third-party sellers.

Yeah I've been mulling that over as well. Heard in a podcast that sterile water works okay enough and it turns out that's pretty standard for most folks across Europe since the other kind can be tough to track down there.

Previously I stuck with plain sterile water injections because finding the correct version in Germany was more effort than I wanted. Not long ago I got some very pure alcohol suitable for this and began creating my own solutions. I'm only describing what I've done personally, not suggesting it to anyone else. Nothing has gone wrong with site reactions or cloudy mixtures yet.

That concept really grabs me so maybe I could try putting one together myself

My first move was looking around for that very pure grade of the alcohol meeting the official specs right here in Britain. I simply would not have tried at all if none turned up.

SteadyBramble67archiveMay 22

This one isn't identical since it skipped those required quality checks and wasn't made for medical purposes.

It looks like the labels match what's described, yet the purity level is listed at just 99.9 percent, which is lower than the 99.95 percent I've come across for pharmaceutical quality before. The entire site gives me a bad feeling, and the text reads as if it was generated by an AI tool.

I purchased from that place and employed it while creating my personal bac, and there were no complications.

QuietFenwick37archiveMay 22

This used to be mine.

I'm wondering whether people usually send this kind of item off to get checked for any problems or if it's okay to assume it's fine. My situation comes from how tricky it can be to locate the preferred option anywhere in Europe.

A large portion of common medications available domestically originate from overseas. Therefore this isn't some shady homemade sterile solution. Everyone accepts different levels of uncertainty. I feel comfortable using this particular sterile water. I relied on regular sterile water initially for several weeks without problems before getting alarmed by certain online communities. Recently I purchased improved acidity test papers to check the level in the near future.

Early on I paid no attention to how the BAC water needed to fulfill its role, but I've realized the importance since then.

I'm also wondering about that yet after looking over just a bit of material on the topic it appears you won't get the cleanest possible setups in a regular house.

I don't think keeping things sterile poses any real problem. You add the concentrated preservative straight into the sealed container holding the sterile water, assuming it has that rubber port on top. Microbes have no chance of lasting in such a strong solution, which means nothing unwanted gets carried over. That's just how I picture the steps working, and if it's off, someone can set me straight.

I think you should file that report. Yesterday I bought a liter of liquid from overseas and the total ended up decent once I added another substance to the order. I also have a purchase from a different place that I made earlier in the year and it still has not arrived due to their really slow service.

WarmAlder80archiveMay 23

My BAC package showed up earlier. This amount ought to last through the shortage.

Guess the van operators hawk that medication these days. This accounts for why supplies ran short, amusingly.

LevelTimber64archiveMay 23

I've come across mentions that a certain bacteriostatic water performs reliably. A group order was set up that came with lab verification. I passed on joining since my existing stock is more than sufficient. It might be worth looking into further.

GreyAlder96archiveMay 24

Got the acidity reading back on the bacterial culture and it measured between 5.5 and 5.75.

I attempted to locate benzyl alcohol suitable for injections and discovered the process was both costly and difficult. I had no idea about that ahead of time. I went ahead and used ordinary 99.5 percent pure material that came without vials only to learn afterward it requires special handling to work for injections. My face ended up swollen and the bumps lingered quite a bit before they faded.

So the ninety nine point five percent version really only fits industrial or laboratory cleaning work. Pharmaceutical grade is necessary because even ninety nine point nine percent comes up short.

CopperFenwick68archiveJun 8

I'm not worried about just one shot. What gets me is the buildup from doing it again and again with that tainted liquid, leading to problems all through the body. Sort of like those old stories about polluted supplies in certain towns. If you catch my drift.
