Why you need BAC Water
You can't skip it
Every peptide on this site comes as a dry powder. Nothing happens until you add this water.
Keeps your vial clean
It has a tiny bit of preservative that stops germs from growing, so a mixed vial stays good for weeks.
One bottle, many vials
A 10 mL bottle mixes about 3 to 5 vials, depending on the peptide.
The right kind
Plain sterile water or tap water is NOT the same thing. Peptides need bacteriostatic water.
Mixing a vial, step by step
Every peptide page tells you exactly how much water to add. The steps are always the same.
- Wipe the tops. Rub the rubber top of both vials with an alcohol swab.
- Pull the water. Use a syringe to pull up the amount of BAC water your peptide's dosing guide tells you.
- Pour it down the side. Push the water in slowly so it runs down the inside wall of the peptide vial. Don't blast the powder.
- Swirl. Never shake. Roll the vial gently between your fingers. Shaking can wreck the peptide.
- Chill it. Give it 5–10 minutes to dissolve, then keep it in the fridge.
