Research tool
Peptide reconstitution calculator
Estimate stock concentration and the draw volume needed for a target amount per administration — the same workflow researchers use when preparing working solutions from lyophilised vials, aligned with how we document mass and purity on our COAs.
Measurement inputs
Enter your experiment variables for lyophilised peptide stocks.
Required volume
Concentration after reconstitution: 2.5000 mg/mL
U-100 insulin scale: 100 units = 1 mL (for translating barrel marks in the lab).
Draw 0.040 mL into a 1 mL syringe for the selected target dose.
How this relates to Precision Health Research materials
Our lyophilised peptides ship with batch-specific COAs so you can reconcile mass on the label with what you add as diluent. This calculator assumes the full labelled mass dissolves into the stated volume; always verify solubility and use appropriate buffers per compound and study design. Browse the peptides hub or full catalogue for SKUs, then cross-check handling notes on your product page and peptide information.
Research use only

Reconstitution quick reference
- After adding diluent, final concentration (mg/mL) = peptide mass in vial (mg) ÷ diluent volume (mL).
- Volume to draw (mL) for a target dose = target dose (mg) ÷ concentration (mg/mL), equivalent to (target dose × diluent volume) ÷ peptide mass.
- On a U-100 insulin syringe, 100 units = 1 mL, so units = mL × 100 (for quick barrel readouts in regulated lab environments that allow this equipment).
