# PeptideConvert

> Free peptide calculators for reconstitution, dosing units, BAC water, blends, GLP-1 vials and lab chemistry. Every formula is shown and every result is checked for common errors.

Core method used by every dosing tool:
- Concentration (mcg/mL) = vial mass (mg) × 1000 ÷ diluent volume (mL)
- Volume (mL) = dose (mcg) ÷ concentration (mcg/mL)
- U-100 syringe units = volume (mL) × 100 (1 unit = 0.01 mL); U-40 units = volume × 40
- Example: 5 mg + 2 mL = 2,500 mcg/mL; 250 mcg = 0.1 mL = 10 units

Important: PeptideConvert tools do arithmetic only. They do not recommend a dose, and nothing on this site is medical advice. Always follow the label and your prescriber.

## Reconstitution & dosing

- [Peptide Reconstitution Calculator](https://peptideconvert.com/peptide-reconstitution-calculator/): Vial mg + BAC water → concentration, draw volume and syringe units.
- [Peptide Dosage Calculator & Chart](https://peptideconvert.com/peptide-dosage-calculator/): Units per dose, weekly totals and a printable dose-to-units chart.
- [BAC Water Calculator](https://peptideconvert.com/bac-water-calculator/): How much bacteriostatic water to add so each dose lands on a clean unit mark.
- [Reverse Peptide Calculator](https://peptideconvert.com/reverse-peptide-calculator/): Turn the units you drew back into mcg or mg.
- [Peptide Blend Calculator](https://peptideconvert.com/peptide-blend-calculator/): Per-peptide amounts in multi-peptide vials such as BPC-157 + TB-500.
- [Doses per Vial & Vial Expiry Calculator](https://peptideconvert.com/doses-per-vial-calculator/): How many doses a vial holds, how long it lasts and whether it expires first.

## GLP-1 peptides
