Peptide Reconstitution Calculator — Free Tool for Researchers

Use this free calculator to instantly determine how much bacteriostatic water to add to your peptide vial, and how much to draw per dose. No math required — just enter your values and get your answer instantly.

How to Use This Calculator

1. Peptide Amount (mg): Enter the total milligrams of peptide in your vial (e.g., 5 for a 5mg BPC-157 vial)
2. Desired Concentration (mcg/mL): Enter your target working concentration. Common choices: 500, 1000, 2500 mcg/mL
3. Desired Dose (mcg): Enter your protocol’s dose amount in micrograms
4. Click Calculate — get your BAC water volume, dose draw volume, and syringe unit mark instantly

Frequently Asked Questions

What units does this calculator use?

The calculator uses milligrams (mg) for peptide amount, micrograms per milliliter (mcg/mL) for concentration, micrograms (mcg) for dose, and milliliters (mL) and microliters (µL) for volumes. The syringe unit output assumes a standard U-100 insulin syringe (100 units = 1mL).

Can I save or print my results?

We recommend copying your results into your lab notebook or research documentation. Take a screenshot of your calculation for your records.

What bacteriostatic water should I use?

For research use, always use USP-grade bacteriostatic water with a Certificate of Analysis confirming HPLC benzyl alcohol concentration and endotoxin testing. Renew Lab Group supplies HPLC-verified BAC water with COA on every order. Order here.
