Hey guys, I’m new here and still learning. I’m confused about this debate about Bac water. Is the Bac water that I bought from Amazon any good? I’m reading here that only Hospira is good and everything else is suspect. I’ve never had any problems so far so what’s the deal here? Can someone explain?
Thanks!
 
Ok, does this mean the peptides I reconed with the generic Bac water is no good?
Peptides are probably fine. Might want to invest in some filtering supplies though, as well as adding additional real BAC water since most of those tested had far less than .9%.
You got any recommendations as to where I can get decent Bac water?
Still $9.99 for real Hospira at one of our sponsors: https://injectionshop.com/sol-ba-diluent-30ml.html/
 
There are very few consumer goods for which I place any stock in brands or branding. But bac water is one. For reasons I can only guess at (expensive to build a sterile production line for low-value product?), no other manufacturer seems to produce it, and Pfizer seems to have no interest in expanding its production line; instead, it restricted sales when demand surged.

So here's my take, which doesn't even have the scientific support of bro science: buy one 30mL vial of Pfizer Hospira bacteriostatic water. Let's say if you pay under $20 it's a great deal. Alcohol-swab its top before removing the 1 or 2 mL you need. Pop it in the freezer next to your big bottle of vodka; bac is water and alcohol, just like your vodka. Put the vodka bottle back after you have a shot. Each subsequent time you want to reconstitute a vial of peptides, move the Hospira vial to the refrigerator the night before to thaw. Alcohol-swab the top (wipes, not vodka), DON'T rinse and do repeat. <$2 per recon.

Does each of us really need a 25 case of bacteriostatic water?
 
Is counterfit Hospira BAC an issue??? nevermind---all over the interweb

You're making a mistake: You're assuming that Hospira water stays better preserved in the freezer. For BAC water, being at cold temperatures means that the alcohol is less effective at preventing the growth of microorganisms. Hospira recommends that you store their water at room temperature.
