Peptide Reconstitution & Dose Calculator

Calculate exact concentrations, draw volumes, and unit conversions for your research protocols. Uses bacteriostatic water as the standard reconstitution solvent.

Quick Presets

Reconstitution Calculator

Add BAC water to a lyophilized vial — calculate the resulting concentration.

Need BAC water? Typically 1–2 mL for most 5mg vials.

FAQ

How much BAC water do I add to a 5mg peptide vial?

The most common approach is 1–2 mL, giving you 5 mg/mL or 2.5 mg/mL respectively. Use the Reconstitution tab above to calculate any combination. Bacteriostatic Water is available in our catalog.

What's the difference between mg and mcg?

1 mg (milligram) = 1,000 mcg (micrograms). So a 5 mg vial contains 5,000 mcg. Use the Unit Converter tab above for instant conversions.

How do U-100 insulin syringe units relate to volume?

On a U-100 syringe: 1 unit = 0.01 mL = 10 μL. So 10 units = 0.1 mL, 50 units = 0.5 mL, 100 units = 1 mL. The Dose Volume tab shows your result in U-100 units automatically.

How should I store reconstituted peptides?

Refrigerate at 2–8°C and use within 28–30 days when reconstituted with bacteriostatic water. Keep lyophilized (unreconstituted) peptides frozen at -20°C.

Why Peptide Reconstitution Math Confuses Researchers

The confusion has a single root cause: three different unit systems operating simultaneously. Peptides are purchased and weighed in milligrams (mg) Peptides are typically dosed in micrograms (mcg) Syringe volumes are measured in milliliters (mL) or insulin units (IU) A researcher holding a 5mg vial of BPC-157, drawing into a U-100 insulin syringe, targeting a 250mcg dose, is working across all three systems in a single preparation. Any unit confusion — treating mcg as mg, misreading syringe markings — produces a dose that may be 10x too high or 10x too low. The foundational conversion to internalize before anything else: 1 mg = 1,000 mcg That single relationship underlies every calculation in this guide.

Storage reference

Storage and handling, briefly

Reconstituted peptides are generally kept refrigerated and used within a window that depends on the compound and the diluent. Bacteriostatic water is chosen precisely because its preservative allows multi-day use of an opened vial. Handling, sterility, and shelf-life are their own topic — see the full reconstitution guide for the practical detail, and always follow qualified professional guidance for anything beyond a research context. Want the numbers and the context for a specific compound? Ask OpenPeptide, the site’s research assistant — it runs this same math and pulls the documented dosing for whatever peptide you’re working with, with sources.
