Step by Step Instructions
Store reconstituted peptides refrigerated at 2 to 8°C. Most remain stable for 4 to 6 weeks after reconstitution. Keep lyophilized vials at room temperature or refrigerated away from light and heat. For research purposes only.
Understanding the Calculation
How Reconstitution Works
Set Your Concentration First
The concentration (e.g. 500mcg/mL) determines how much water to add. The calculator divides your vial amount by the concentration to give you the exact mL to add.
Syringe Units
A 1mL insulin syringe has 100 units. Each unit = 0.01mL. Your dose volume is converted to units so you know exactly where to fill to.
Lower Concentration = More Water
A lower concentration means adding more water. This gives you more units to draw per dose, making smaller doses easier to measure precisely.
Higher Concentration = Less Water
A higher concentration uses less water. Useful when you want fewer injections per vial or a smaller injection volume.
