How do you guys mitigate the cost of Bac water

[PablinhoDoFavela]

I just found out once opened Bac water vials have 28 days for use. Apparently it cant be frozen to last longer either.

I looked into 3ml bottles but apparently these are not safe for personal use.

How do you guys mitigate the prices?

28 days. Oh no, I must be in trouble…. Don’t think that is the standard most folks follow.

 

[Mr. Blonde]

I definitely don't follow that. I've used at least 90 day opened bac (maybe older). As long as it is clear and stored properly, I'll blast it.

How is it “stored properly”’?

After I open mine, I put it in the fridge but idk how sterile that is

 

[woundcarping]

I go 3 months from the first stick, I label the bottle with the date.

As far as the cost… that’s $3-4/month…

Where do you store it after the first use and how do u know is still good to keep on using

 

[RubbaDubba1]

I'm up to 5 months on a bottle, keep in the store room nice and cool and don't refrigerate after opening it. It has to be your comfort level, I've read of people using bottles many years after it expired.

I understand at hospitals they are kept at room temperatures.

You don't have to refrigerate it. I keep mine in a box in a cabinet, at room temperature, and out of sunlight.

Just always double check that it looks clear, and you will be good to go.

 

[Dos-Dox]

I use mine for ~90 days. Lately, I’ve been using a vial spike and I store it in a 3D printed single BAC storage box (the tall version) with a Curos cap on the spike’s Luer port and I keep the whole thing in the fridge.

 

[woundcarping]

In a drawer not of the fridge.

It’s just a guess, but it’s worked before.

 

[anhydrous]

It doesn't cost very much and I can recon what I'll need for the foreseeable future with a single bottle and then freeze them for future use.

 

[Vash]

Definitely use mine past 28 days and even if I didn’t, they’re only $10/bottle.

Same. I keep mine in a cabinet in the garage with a bunch of my other supplies.

That's a good idea.

Just stop at the plasma and sperm banks for donations on the way to the BAC store and that should cover the cost. 😉

I've always scratched my head on the notion of an expiration date for BAC water. Obviously if you're engaging in unsanitary practices and slowly contaminating the BAC vial over time you could run into a problem at some point, but if you're not injecting air into the vial (which some people apparently do), what exactly is the aging concern people are fretting will happen in weeks to a few months?

I'm obviously aware of what the label and documentation from the manufacturer says, but neither addresses my question.

It's kind of like that do you use the ketchup/condiments by the expiration date or do you toss it?

 

[foffspam111]

I bought a single vial 3d printed case for bac and use it till it’s gone. I guess that’s 3-4ish months. The case protects the top and keeps all light out. Store it in a cool dark place. Aka my office closet. The case is great.

Hospira 3ml vials-Top dresser drawer and use it till it's gone which is less than three months...generally. Just what I do-not medical advice. Like others have said, if it "looks Ok to me"...I use it.
This is settled "SCIENCE and peer-reviewed". 😉 🤣🤪

Where did you find this out? The labeling document on pfizer.com makes no mention of this. I have heard of 28 days for reconstituted peptides but never BAC water. Hospira prints an expiration date on the bottle that far exceeds 28 days and makes no mention of 28 days after opening.

It's a regulated compound. The manufacturer spent the money to study the specific use case where it was kept at room temperature and continually used for a period of 28 days and found that it still retained its bacteriostatic properties. Since that is what was studied that is the only guidance they can legally provide without claiming more than what their study demonstrated.

People get tripped up over this and assume it means it somehow goes bad on day 29 since that condition was not studied and therefore the manufacturer can't recommend it.

People similarly get tripped up over refrigerating it, as likewise that condition wasn't studied so the manufacturer can't recommend it.

The entire premise is humorous to those with chemistry backgrounds.

28 days is just so you buy more, store it in a place that’s room temp or cold without sunlight and u can keep it for a while. And also, bac water is insanely cheap even if u only use it for 28 days. Bac water is like 10$ for 30ml

 

[HereKittyKitty]

Don't know about y'all but I spend meaningful money on the peps. The cost of bac and supplies is nothing in comparison.

I have Nexus, Hospira, PGB bac water in my linen closet.

I think he found it on gptchat:

✅ Best Way to Store Opened BAC Water

1. Refrigerate After Opening

• Temperature: 2–8 °C (36–46 °F)
• Refrigeration slows bacterial growth and preserves sterility.
• Do not freeze (freezing can compromise the solution and vial integrity).

⚠️ Important Safety Notes

• BAC water contains 0.9% benzyl alcohol, which inhibits bacterial growth but does not make it sterile forever.

 

[ESSO88]

Ensure you lateralise the top before withdrawing any BAC to reduce the change of contamination

 

[toologic]

I just put the bottle inside a empty script bottle or I also have caps for the bottle and put in the fridge. I put my 3ml vials inside some lancet bottle as they are small.

What's this Nexus stuff?

I don't understand why insulin vials are 90 days, compounded sema and tirz are 90 days but the BAC water they (assumingly) are made with some say is 28 days. Did someone come up with 28 days because we are not using a sterile lab or is this for labs too?

I go 90 days in ziploc bag fridge with everything, sometimes a little longer if not visually bad. I filter everything to new vials and cross my fingers sometimes.

I would really like to see a group test of Hospira where they use all but 10ml and store it for 5 months (or longer) before sending for testing.

You're comparing something that is designed to be used by one person repeatedly VS something that is designed for medical staff to use in a shared environment with different practitioners of varying skill level all sharing the same vial.

 

[Dydanz]

I use mine for 3 months

Obviously if you're engaging in unsanitary practices and slowly contaminating the BAC vial over time you could run into a problem at some point, but if you're not injecting air into the vial (which some people apparently do),

hold up wait a minute
