Peptide Reconstitution Calculator

Reconstitution is the process of mixing lyophilized peptide powder with bacteriostatic water. We've pre-filled the calculator with the standard vial size and starting dose for LACTOFERRICIN B. You can adjust the values below to match your specific protocol.

Frequently Asked Questions

How much bacteriostatic water should I add?
Most users add 1-3 mL. More water = lower concentration = easier to measure small doses. Use our Reverse Calculator to find the optimal volume.
What is the concentration after reconstitution?
Concentration = vial size (mg) ÷ water added (mL). For a 5 mg vial with 2 mL water, the concentration is 2.5 mg/mL.
How do I read insulin syringe units?
Each "unit" on a U-100 syringe = 0.01 mL. A 0.3 mL syringe has 30 units, a 0.5 mL syringe has 50, and a 1.0 mL syringe has 100.
Does the peptide type matter for reconstitution math?
No — the reconstitution formula is universal. Concentration depends only on vial size and water volume, not the specific peptide.
How long does a reconstituted vial last?
21-28 days when stored at 2-8°C (refrigerated) after reconstitution with bacteriostatic water.
