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.
