How to mix a vial.
Preparation depends on the exact product. Adding water to a research powder does not establish that it is safe to inject.
- Adding water back to the powder is called mixing, or reconstituting.
- Bacteriostatic (BAC) water is sterile water with a tiny bit of benzyl alcohol. Never use tap or bottled water.
- Wipe each stopper with a fresh alcohol swab, and swab it again every time you draw.
- Let the water run slowly down the glass, then swirl until clear. Don't shake it.
- Approved pens and ready-to-use solutions need no water. Don't add any.
Step by step
Use only the diluent and equipment specified for the exact product. Bacteriostatic water does not sterilize a contaminated powder or remove endotoxin.
- Wash your hands Then flip the caps off both vials.
- Swab both stoppers A fresh alcohol swab for each one.
- Check the diluent Use the specified type and volume. An example calculation does not validate a mixing recipe.
- Add it slowly, down the glass Never spray it onto the powder.
- Swirl, don't shake Swirl gently until it's completely clear. Shaking can damage the fragile peptide chains.
- Store as labelled Temperature and discard time depend on the exact formulation. Cold doesn't sterilize it, so swab the stopper every time.
The water sets the strength
Vial size (mg) and the water you add (mL) set the strength. More water means a weaker mix and more units per dose, not a bigger dose. Lesson 6 walks through the math.
Can't remember the numbers? The Dosing tool turns your vial, water and dose into units on a U-100 syringe.
