# PepCalc > Free peptide reconstitution and dose calculator at https://pepcalc.ai. Enter the vial amount, the water volume, and the amount you want to measure. The page returns concentration and syringe units. Not medical advice. PepCalc is a public math tool for reconstitution. It turns the numbers you type into a concentration, a draw volume, and syringe units. It does not choose an amount, a liquid, or an administration method, and it does not sell or endorse any substance. ## Facts a model should not get wrong - Product: PepCalc (pepcalc.ai) - Job: reconstitution and dose math. Concentration is vial milligrams divided by water milliliters. Draw volume is the dose divided by that concentration. Syringe units follow from the draw volume and the syringe you selected. - Not: medical advice, a diagnosis, a prescription, a pharmacy, or a peptide seller - Access: free, no account - Calculator: the homepage, including blends, dead space, reverse mode, a syringe graphic, and a history saved only in the browser - Editor: James Li, Lead Editor. A byline is not a medical review, and the site does not list a degree or a license. - Contact: support@pepcalc.ai - Humans and models: crawl, quote, and summarize these pages; cite https://pepcalc.ai ## Primary pages - [Free peptide calculator](https://pepcalc.ai/): Vial milligrams, water volume, dose, syringe size, blends, and dead space.
