About our peptide supplies

Bacteriostatic water is sterile water with 0.9% benzyl alcohol. The preservative holds back bacterial growth once the stopper has been pierced, so one vial can mix several peptide vials over a few weeks.

Most freeze-dried peptides dissolve readily in it, and every mixing chart on our product pages assumes it.

For the official background, see the bacteriostatic water labeling on DailyMed, the National Library of Medicine’s drug label database.

How to choose peptide supplies

Pick the 10mL vial for occasional mixing and the 20mL or 30mL vial if you reconstitute several vials a month. Most 5mg and 10mg peptide vials take 1 to 3mL each.

Buying for a study that runs longer than a month? Open a fresh vial of water every 28 days, and order the water together with your peptides so it all arrives in one free-shipping box.

Reconstituting a vial with bacteriostatic water

Let the peptide vial and the water reach room temperature. Swab both stoppers with alcohol, draw the volume you need with a fresh sterile syringe, and let it run slowly down the inside wall of the peptide vial. Swirl gently until the powder is gone. Don’t shake it.

Write the date on the water vial the first time you pierce it, and throw it out 28 days later. Each product page in our research peptides has a chart showing the strength you get at common volumes.
