Reconstitution

A short and careful guide.

Most Lumira compounds arrive as a lyophilized powder and require reconstitution with bacteriostatic water before use.

What you will need

  • Your Lumira vial (at room temperature)
  • Bacteriostatic water — 0.9% benzyl alcohol in sterile water
  • A sterile 1mL insulin syringe
  • A fine-gauge needle (27–29G)
  • Alcohol wipes (isopropyl 70%)
  • A clean, well-lit work surface

The process

  1. Allow the vial to come to room temperature before use.
  2. Wipe the rubber stopper of both vials with an alcohol wipe. Allow to air-dry.
  3. Draw the calculated volume of bacteriostatic water into the syringe.
  4. Insert the needle at an angle and let the water run slowly down the inside wall — never directly onto the powder.
  5. Do not shake. Roll gently between your palms until fully dissolved.
  6. Inspect — solution should be clear. If cloudy, do not use and contact us.
  7. Refrigerate at 2–8°C, protected from light. Stable for 28–30 days.

Dilution math

Divide total peptide content (mcg) by bac water volume (mL) = concentration per mL. Then divide your target dose by that concentration = draw volume in mL.

Example: 10mg vial + 2mL bac water = 5,000mcg/mL
250mcg dose: 250 ÷ 5000 = 0.05mL (5 units on U100 syringe)
