The reconstitution step that decides if your vial survives
Machine-readable facts for this Lab article. The full page is https://www.preppinpeppers.com/blogs/the-lab/the-reconstitution-step-that-decides-if-your-vial-survives.
TL;DR
Reconstitution turns lyophilized peptide powder back into a liquid. Adding diluent gently down the vial wall dissolves the powder without damaging it.

FAQ
- What is the difference between bacteriostatic water and sterile water for reconstitution?
- Bacteriostatic water contains a small amount of benzyl alcohol as a preservative, which allows a vial to be safely accessed multiple times. Sterile water has no preservative, so a vial mixed with it should be treated as single-use.
- Why shouldn't you shake a peptide vial to dissolve the powder?
- Shaking adds mechanical stress to the peptide while it's mid-dissolve, which can break the weak bonds holding its folded shape together. Gentle swirling dissolves the powder just as well without that risk.
- How do you calculate peptide concentration after reconstitution?
- Divide the milligrams of peptide in the vial by the milliliters of diluent you add. The result is your concentration in mg/ml, which is the basis for every volume measurement afterward.
