What is Genetek bacteriostatic water?

Sterile water preserved with 0.9% benzyl alcohol, allowing a reconstituted peptide vial to be drawn from multiple times over several weeks rather than used once. Supplied by Genetek in a sealed multi-dose vial with a self-sealing stopper.

Use only for reconstituting research peptides — not for injection into humans or animals.

Genetek bacteriostatic water reconstitution reference

Reconstitute with bacteriostatic water. The table shows the concentration and syringe volume produced by common dilutions of a 10mg vial, for reference when preparing research stock solutions.

Units measured on a standard U-100 insulin syringe (100 units = 1 ml). For other vial sizes use the peptide reconstitution calculator.

Storage & handling

Before reconstitution
Store lyophilised at −20 °C, protected from light. Stable for 24 months or longer in the sealed vial.
After reconstitution
Store at 2–8 °C and use within 28 days. Avoid repeated freeze-thaw cycles; aliquot where possible.

Frequently asked questions

What is bacteriostatic water?

Bacteriostatic water is sterile water preserved with 0.9% benzyl alcohol, which inhibits bacterial growth so a reconstituted peptide vial can be drawn from multiple times over several weeks instead of being used once.
