Reconstitution is the process of dissolving a lyophilized (freeze-dried) peptide powder into bacteriostatic water to create an injectable solution. The reconstitution calculator helps you determine the correct volume to use for your target concentration.
Bacteriostatic water is sterile water preserved with 0.9% benzyl alcohol, which inhibits bacterial growth. It is the standard diluent for reconstituting research peptides and allows multi-dose vials to remain stable for weeks when refrigerated.
Use our free Peptide Reconstitution Calculator. Enter your vial size (mg) and the volume of water added (mL), and the calculator outputs the resulting concentration and the equivalent volume for a given amount.
All dosing data in our peptide profiles is sourced from peer-reviewed research, clinical trial registries, and published pharmacokinetic studies. Figures are labeled "Doses Reported in Published Studies" and are presented for research purposes only — not as medical recommendations.
