Peptide Reconstitution Calculator
Work out exact concentration, dose volume, and syringe units for lyophilized research peptides. Enter your vial strength, how much bacteriostatic water you added, and your target dose.
Your Protocol
Typical research dosing: 0.25–2.4 mg SC once weekly (human RCT dosing); 2.4 mg is the approved obesity dose.
Results
Dose = 0.25 mg of Semaglutide ()
Formula: concentration (mg/mL) = vial strength ÷ water added. Dose volume (mL) = target dose ÷ concentration. Syringe units = dose volume × total syringe units. Always verify your math against the Certificate of Analysis and reconstitution instructions for your specific vial.
Research use only. Peptides sold as lyophilized research chemicals are not approved for human use. This calculator is a math tool for laboratory reconstitution planning — it is not medical advice. See our reconstitution guide for storage and handling best practices.
