Insulin Syringe Units Explained for Lab Use
A unit on a U-100 syringe is 0.01 mL, a volume and not a dose. Here is how to convert concentration to units and why dilution improves measurement accuracy.

Why You Swirl Peptides Instead of Shaking
Shaking creates shear at the air liquid interface and foams the solution. Both denature peptides invisibly, so the vial looks perfect and no longer works.

What Lyophilized Peptide Powder Is
Lyophilization freeze dries a peptide into a stable solid by removing the water it needs to degrade. Reconstitution reverses that, and starts the clock again.

How to Store Reconstituted Peptides
Refrigerate at 2 to 8 C, protect from light, avoid freeze thaw cycling, and discard at 28 days from first puncture. Storage is where most sample loss happens.

Peptide Reconstitution Calculator: The Math
Concentration is vial mass divided by water volume. Work out mg/mL for any vial, convert it to syringe units, and choose a volume you can measure accurately.

Bacteriostatic vs Sterile Water: The Difference
Sterile water has no preservative and is single use. Bacteriostatic water contains 0.9% benzyl alcohol, which is what allows a vial to be entered repeatedly.

What Is Bacteriostatic Water?
Bacteriostatic water is sterile water preserved with 0.9% benzyl alcohol, which suppresses bacterial growth and lets a single vial be accessed many times.
