Users report that sterile water works fine for short-term use of a week or two if sterile technique is followed, and some have done so repeatedly without issues. BAC water is viewed as preferable for longer storage since guidelines allow 28 days and many extend beyond that, but it is difficult to obtain in Europe and generally requires a prescription. Hospira specifically is noted as hard to source locally, with imports from outside the EU also restricted. Several participants confirm that all injection-grade diluents have long required prescriptions in the US as well.
What this discussion establishesWhether BAC water provides meaningful benefit over sterile water when vials are used within a week or two.
Nothing here is advice.
Planning to reconstitute my first 10 mg tirze vial in the coming days. Tried sourcing Hospira BAC water but could not locate any seller shipping to Europe. Two choices available: BAC water from the same place that sold the peptide, or plain sterile water. Since the vial will be finished in one week at 5 mg per week, either option appears acceptable. Looking for input from anyone else in Europe who ran into this and what choice they made. Also interested in any way to obtain Hospira within Europe.
BAC water stays usable well past one week. Official guidance lists 28 days, yet people here have gone longer; one 30 ml vial lasted six months. Hospira is basically unavailable in Europe and very hard to locate. Importing from Canada is possible but BAC remains prescription-only across the EU.
Is that a governmental rule, or more like the recent Pfizer change in the USA that seems entirely non-governmental from what I can tell?
The vial I mentioned was the tirze one, not the BAC vial. Appreciate the reply anyway.
No idea on the exact rule, but the EU tends to be stricter than the USA overall.
Sterile water is the usual choice here in Europe and people keep the vial for a while. I have used that approach myself for a couple of weeks and had no trouble. For just one week I would not worry much, as long as basic sterile handling is followed so nothing unwanted gets into the vial.
Not a recent rule in the USA. Any BAC water meant for human injection use has always needed a prescription. Sellers simply did not enforce it strictly until lately. Products on Amazon that contain 0.9 % benzyl alcohol avoid the prescription rule by labeling themselves for research use only.
That checks out. I looked at my own Hospira vial and it does state that a prescription is required.
Someone mentioned in an interview that their lab always uses sterile water instead of BAC and simply tracks the first-use date then discards after 28 days. They felt BAC was not worth using since the vial gets tossed on the same schedule anyway. Most people here still prefer BAC and I have kept vials for two or three months without problems, possibly because that source never used it themselves.
