Enter the mass in your vial and your desired concentration, and the Reconstitution Calculator tells you exactly how much solvent to add — plus your final solution volume and concentration per ml so you know precisely what you're working with.

The amount of bacteriostatic water depends on the peptide mass and your desired concentration. Use our calculator to determine the exact volume needed for accurate reconstitution.
mg/ml (milligrams per milliliter) is 1000 times stronger than μg/ml (micrograms per milliliter). Choose the appropriate unit based on your peptide strength and dosing requirements.
After reconstitution, divide your desired dose by the final concentration to determine the volume to draw. For example, if you want 0.5mg from a 1mg/ml solution, draw 0.5ml.
Yes, this calculator works for peptides, proteins, antibodies, and other lyophilized substances that need reconstitution. Always follow manufacturer guidelines for specific products.
Reconstituted peptides typically last 2-4 weeks when stored properly in the refrigerator. Some peptides may remain stable for longer periods when frozen.
Adding too much solvent creates a weaker concentration, while too little creates a stronger one. Use precise measurements and our calculator to achieve the exact concentration needed.
For most peptides, the powder volume is negligible compared to the solvent volume. However, for large molecules or significant amounts, you may need to account for displacement volume.
