PeptideComparePeptide calculator.
Convert vial strength and BAC water into draw volume and concentration, work backwards from a target unit count, or plan a multi-peptide blend — three tools, one page. Unit conversion only — no dosing advice, no protocols.

How it works
Enter your vial size
Find the total peptide amount on the label and enter it in milligrams (e.g. 10 mg). Common sizes are 5 mg and 10 mg.
Set the BAC water volume
Choose how much bacteriostatic water was added — 1, 2, 3 or 5 mL, or a custom amount. More water = lower concentration and larger draw volume.
Enter the target quantity
Type the target amount per administration, in mcg or mg. The calculator divides it by the vial content and multiplies by the water volume.

Reconstitution tips
- Use bacteriostatic water — contains 0.9% benzyl alcohol for preservation.
- Add liquid slowly — aim down the vial wall, not onto the powder.
- Never shake — gently swirl or roll until fully dissolved.
- Store cold — refrigerate reconstituted solutions at 2–8 °C.
- Use within 28 days — most solutions stay stable for ~4 weeks.
