Bacteriostatic Water at a glance

This listing is a laboratory supply, not an active compound. Bacteriostatic water consists of sterile, pyrogen-free water with 0.9% benzyl alcohol added to suppress bacterial growth, packaged in sealed vials with a rubber septum. It is the diluent most often paired with lyophilized peptides on GLP1 Forum Escrow, because the preservative lets a vial be punctured several times over the course of a project without the liquid becoming a source of contamination.

Price and availability

A single 30ml vial from Sulan Bio, shipped from Guangzhou, China. It is listed at $20.00. Funds stay in escrow and are released to Sulan Bio only when you mark the order as received.

Lab testing

There is no public lab report for this listing yet. We can ask the brand for the batch COA before you order. Many buyers also split an independent HPLC test with others who bought the same batch.

Bought through escrow: the brand is only paid after you confirm delivery. If the parcel never arrives, or an independent test shows the wrong compound or a significant under-fill, open a claim before releasing payment.

What it is studied for

There is no receptor pharmacology here. The relevant mechanism is the preservative: benzyl alcohol at this concentration is bacteriostatic, meaning it slows or halts bacterial multiplication rather than reliably killing every organism. It is thought to act by disturbing microbial cell membranes. That protection is useful when a stopper is entered repeatedly, but it does not sterilize contaminated material, and its activity against some fungi and spores is limited. Benzyl alcohol can also promote aggregation of certain proteins, which is why some materials specify preservative-free water instead.

Research and regulatory status

Bacteriostatic water has no research literature of its own in the sense that a peptide does. Its composition follows long-standing pharmacopeial monographs, and versions are marketed as pharmaceutical diluents. Product labeling carries a long-standing warning against use in newborns because of benzyl alcohol toxicity reported in that group. For catalogue purposes, the useful questions are sterility, preservative strength and packaging integrity rather than any form of efficacy.

Checking the lab data

A meaningful certificate for a diluent focuses on different tests than a peptide report. Expect sterility testing, a bacterial endotoxin result, and an assay confirming benzyl alcohol near 0.9%. pH, clarity and freedom from visible particles are routine checks. The vial seal and stopper should be intact, and the lot number and expiry date on the label should match the paperwork. There is no mass spectrometry identity test to expect here.

No independent report is attached to this listing yet. You can compare brands that publish one on the marketplace or browse the lab reports directory.

Buyer questions

Does bacteriostatic water expire?

Yes. Each vial carries a manufacturer expiry date for the sealed product, and once the stopper has been punctured, pharmacopeial practice limits how long an opened multi-dose vial is kept. Checking the printed lot and expiry, and discarding vials with cloudiness or particles, is standard laboratory practice.

Is bacteriostatic water tested like the peptides on this site?

Not in the same way. Peptide reports focus on the identity and purity of a molecule, while a diluent report should show sterility, endotoxin levels and preservative concentration. A third-party certificate covering those points is the closest equivalent to the HPLC and mass-spec reports attached to peptide listings.

How much Bacteriostatic Water is in this listing?

One vial of 30ml. Where a lab report exists, the testing panel above shows the measured content of the tested sample.

When does Sulan Bio get paid?

Only after you confirm delivery. Until then the payment is held in escrow, and you can open a claim if anything is wrong with the order.
