Protocol // Reconstitution
How to properly reconstitute a peptide
-
01
Prepare your workspace
Work on a clean, well-lit surface. Disinfect gloves and the surface with 70% isopropyl alcohol, and wipe both rubber stoppers with a fresh swab.
-
02
Prepare the peptide and the solvent
Let both vials come to room temperature for 15–20 minutes. Use bacteriostatic water (0.9% benzyl alcohol). More water = lower concentration = larger, easier-to-read syringe marks.
-
03
Add the solvent into the vial
Draw the calculated amount of bacteriostatic water. Tilt the peptide vial at 45° and release the water slowly down the inner wall — never directly onto the powder.
-
04
Dissolve and store
Do not shake. Gently swirl until the solution is clear, label the vial with the date and keep it refrigerated at 2–8°C.

How it works
Reconstitution, without the guesswork
What the calculator is doing with your numbers.
Most peptides ship as a freeze-dried powder that has to be mixed with bacteriostatic water before use. The water you add sets the concentration, and the concentration decides how far to pull the syringe for each dose.
- Vial size is the milligrams of peptide in the vial, printed on the label.
- Bacteriostatic water is how much you add, in millilitres.
- Dose is what you want per draw, in micrograms or milligrams.
The calculator turns those numbers into units on your syringe, so there is no conversion to do by hand. Check each vial’s strength against its lab report, and browse peptides for vial sizes.
