Peptide Reconstitution Calculator
Enter the compound mass in the vial, the liquid volume, and the amount you want per sample. It returns the solution concentration and the exact volume to measure out — with a blend mode showing how much of each compound a combined vial contains per sample.
Sometimes searched for as a “peptide dose calculator,” this is not a human peptide dose calculator and offers no dosing guidance. It is a laboratory reconstitution calculator that computes solution concentrations and the volume to measure out, for research use only.

Frequently asked questions
Is this a peptide dose calculator?
No. This is not a human peptide dose calculator and it does not provide dosing guidance. It is a laboratory reconstitution calculator that converts the compound mass in a vial and the volume of reconstitution liquid into a solution concentration and the volume to measure out per sample, for in-vitro research use only.
What does the calculator actually compute?
It divides the compound mass by the liquid volume to get the concentration in mg/mL, then returns the volume needed to obtain a target amount per sample, expressed in millilitres (mL), with an optional U-100 graduation scale shown only as a measurement reference.
What is reconstitution liquid (bacteriostatic water)?
Reconstitution liquid is the diluent used to dissolve a lyophilised (freeze-dried) compound so it can be handled as a solution of known concentration. Bacteriostatic water is a common choice at the laboratory bench.
Does “research use only” mean a compound is approved for people?
No. Compounds labelled research use only are not approved by the FDA for human or veterinary use and are supplied strictly for in-vitro laboratory research. This tool does not support or recommend administration of any compound to humans or animals.
Research use only — not for human or veterinary use. Several compounds selectable above (including BPC-157, TB-500, ipamorelin, CJC-1295, GHK-Cu, melanotan II, MOTS-c, and retatrutide) are not approved by the U.S. Food and Drug Administration for the prevention, treatment, or cure of any medical condition, and are supplied strictly for in-vitro laboratory research. Others (such as semaglutide, tirzepatide, tesamorelin, and bremelanotide) are approved only as prescription drugs; research-grade material is not the approved product. This tool is a laboratory reconstitution aid. It computes solution concentrations and measurement volumes from the numbers you enter, and expresses volume on a standard U-100 graduation scale (100 graduations = 1 mL) purely as a measurement reference. It does not verify a vial's contents or purity, is not dosing guidance, and does not support or recommend administration of any compound to humans or animals. These statements have not been evaluated by the FDA. Always confirm calculations independently and handle all material in accordance with applicable laboratory-safety and regulatory requirements.
