Peptide calculator

Amount to volume

Convert an amount supplied by your veterinarian using the exact concentration on the pharmacy label. This tool does not select a dose, mixing instructions, or a treatment for your pet.

Peptide amount and concentration

Enter positive decimal numbers using a decimal point. Use the same single ingredient for both entries. Total vial weight, blend totals, pen clicks, and syringe “units” are not a concentration.

Volume = amount ÷ concentration, using matching mass units. Confirm the result and measuring device with your veterinarian or pharmacist. No entries are saved or sent.

Concentration calculator

Reconstitution calculator

Check concentration using a confirmed ingredient amount and the final solution volume specified by the pharmacy. Final volume is not necessarily the volume of liquid added.

Confirmed amount and final volume

Use one ingredient. A combined blend weight cannot establish the concentration of each ingredient.

Arithmetic only. This does not choose a diluent, how much liquid to add, a dose, or a preparation method. Confirm any difference from the pharmacy label. No entries are saved or sent.

A guide for your cat, too.

Start with the species, exact ingredient, and reason you are considering a product. A finding in dogs does not automatically answer a question about cats.

A few questions before you start.

Know what these guides can help you do.

Are oral and injectable peptides interchangeable?

No. Assess the exact ingredient, formulation, species, route, and intended purpose. Read our oral vs injectable comparison.

Does the calculator recommend a serving?

No. It calculates cost from a confirmed schedule you enter. It does not determine a dose or rank clinical effectiveness.
