Precision Laboratory Tool

Peptide Reconstitution & Concentration Calculator

Use this interactive laboratory tool to calculate reconstitution dilutions with Bacteriostatic Water and precise syringe unit graduations.

Peptide Vial Mass (mg): e.g. 5mg, 10mg, 30mg, 50mg

Volume of BAC Water Added (mL): e.g. 1 mL, 2 mL, 3 mL

Target Laboratory Research Dose (mcg): Note: 1000 mcg = 1 mg

5000 mcg/mL

U-100 Insulin Syringe Mark (100 IU = 1 mL):

5.0 IU

Volume: 0.050 mL

Formula Used:
Concentration = (Vial mg × 1000) ÷ BAC Water mL
Syringe Units = (Target Dose mcg ÷ Concentration) × 100

Based on a standard U-100 insulin syringe (1 mL = 100 units):

Vial Size	BAC Water Added	Concentration	10 Units Draw	20 Units Draw	40 Units Draw
5 mg Vial	1.0 mL	5.0 mg/mL	0.5 mg (500 mcg)	1.0 mg (1000 mcg)	2.0 mg
5 mg Vial	2.0 mL	2.5 mg/mL	0.25 mg (250 mcg)	0.5 mg (500 mcg)	1.0 mg
10 mg Vial	2.0 mL	5.0 mg/mL	0.5 mg	1.0 mg (1000 mcg)	2.0 mg (2000 mcg)
10 mg Vial	1.0 mL	10.0 mg/mL	1.0 mg (1000 mcg)	2.0 mg (2000 mcg)	4.0 mg

1. Wipe Clean: Clean stoppers of both vials with alcohol swab.

2. Equalize Pressure: Inject equal air into BAC water vial before drawing water.

3. Add Gently: Stream water down the inside glass wall at an angle.

4. Mix Thoroughly: Swirl vial gently until clear. Never shake.
