# Peptide Calculator Suite

> Free browser-based calculator for reconstituting lyophilized peptides. It turns vial mass, bacteriostatic water volume, and target dose into concentration (mg/mL), injection volume (mL), and units on a U-100 insulin syringe, and shows the fill line on 30, 50, and 100 unit barrels. Educational use only, not medical advice.

All math runs in the browser. The site stores nothing about visitors and needs no account.

- [Peptide Reconstitution Calculator](https://peptidecalculatorsuite.com/): BAC water volume, concentration, dose in mL and syringe units, syringe fill-line preview, split-dose schedule, and 28-day expiration tracker

## Blogs

- [How to Reconstitute Peptides: Complete Step-by-Step Preparation Protocol](https://peptidecalculatorsuite.com/blogs/how-to-reconstitute-peptides): Reconstitute a peptide vial step by step: vent the vial, add the BAC water slowly, swirl gently, and store it, with the exact water volume worked out first.
- [How Much Bacteriostatic Water to Add to a Peptide Vial: Volume Selection](https://peptidecalculatorsuite.com/blogs/how-much-bac-water-to-add): More BAC water makes a weaker solution and a bigger draw; less makes it stronger and smaller. See where each choice puts your dose on the syringe marks.
- [Peptide Reconstitution Math: Milligrams, Milliliters, and Syringe Units](https://peptidecalculatorsuite.com/blogs/peptide-reconstitution-math-explained): Convert a peptide dose from mg or mcg to mL and insulin syringe units step by step, with worked examples, common mistakes, and practice problems.
- [Insulin Syringe Units to mL Conversion: 30U, 50U, and 100U Barrels](https://peptidecalculatorsuite.com/blogs/u100-syringe-units-to-ml-conversion): Convert insulin syringe units to mL, compare 30, 50, and 100 unit barrels, and pick the syringe that measures your peptide dose most accurately.
- [Tirzepatide Reconstitution and Dosing: Syringe Units for Every Vial](https://peptidecalculatorsuite.com/blogs/tirzepatide-reconstitution-and-dosing): Tirzepatide syringe units for every label dose from 2.5 to 15 mg, at 5, 10, 15, and 30 mg vials mixed with 1, 2, or 3 mL of BAC water.

## Core formulas

- Concentration (mg/mL) = Peptide in vial (mg) / Bacteriostatic water added (mL)
- Dose volume (mL) = Dose (mg) / Concentration (mg/mL)
- Syringe units (U-100) = Dose volume (mL) × 100
- Micrograms per unit = Concentration (mg/mL) × 10
