I wrote today to ask what the expiry date is for the vials they would send me.
Noah from Peptide Shop answered that bac water vials "don't have an expiration date but it is better to get a new one after 2 month because it is not sterile anymore".
I really don't know what to think
You must conclude for yourself
@MrsMUffin, my own observation is that Noah from Peptide Shop is mistaken on the facts, an opportunist, and likely an ---hole.
There is good reason to expect that an
unopened, unfrozen vial of Bacteriostatic Water for Injection USP
kept at room temperature in a dark place will last far
longer than one year.
Further...
- "While it is essential to follow proper storage guidelines and use unexpired solutions whenever possible, using bacteriostatic water past its expiration date is generally safe. The expiration date primarily indicates when the manufacturer guarantees the solution’s stability and potency, but it does not mean the solution becomes immediately harmful once it expires."
- from Bacteriostatic Water Australia, a leading supplier of BWater.
Benzl Alcohol, the anti-microbial active ingredient in Bac Water, is a very stable molecule. As a reagent-grade lab chemical it is considered to have
a shelf life of 3 (three) years unopened, room temperature, dark place etc. Numerous suppliers of lab chemicals make the 3 years unopened statement, some suggest that a re-test is warranted after two years unopened.
Also commonly stated by chemical suppliers is that "
shelf life after being opened is One Year".
Much of the angst online about Bacteriostatic Water stems from the FDA labelling requirement for "multiple patient/multiple use" scenario that this product was produced for. The "28-day after first use" expiration label is
intended to minimize cross-patient infection, not a concern about product age.
In our "single patient/multiple use" scenario there IS NO RISK of cross-patient infection. In fact there was no short expiry date on Hospira Bac Water vials intended for single patient use until recently. The change of labelling requirement by the FDA was made because of improper institutional use of the "single-user" product for extended periods in large patient populations; there were in fact infection outbreaks as might be expected.
