How to use the vials.

Lyophilized peptide vials are prepared one at a time with bacteriostatic water, clean handling, and clear records. The steps below keep the process simple and documented.

What is needed

  • Lyophilized peptide vial
  • Bacteriostatic water
  • Sterile syringes for reconstitution and drawing
  • Alcohol wipes
  • A clean work surface and a written record of vial strength, water volume, batch, and date

Reconstitute one vial at a time.

  1. 01

    Check the vial and records

    Confirm the peptide name, vial strength, batch number, and COA before opening anything. Record the planned water volume before reconstitution starts.

  2. 02

    Clean the tops

    Wash hands, prepare a clean surface, and wipe the rubber stoppers on both vials with alcohol. Let the alcohol dry before puncturing the stopper.

  3. 03

    Add bacteriostatic water slowly

    Draw the planned water volume with a sterile syringe, then inject it down the inside wall of the peptide vial. Aim the stream at the glass, not directly into the powder.

    • Add water slowly to reduce foaming.
    • Do not shake the vial.
    • If powder remains on the side, roll or swirl the vial gently until dissolved.
  4. 04

    Store after reconstitution

    Place the vial in the refrigerator at 2-8°C after reconstitution. Keep it upright when possible, protected from light, and use a dated label.

    • Before reconstitution, unopened lyophilized vials are best kept cold and dry. Use -20°C for longer storage or 2-8°C for short-term handling.
    • After reconstitution, keep refrigerated at 2-8°C and use within 30 days unless the product label or research plan sets a shorter window.
  5. 05

    Draw measured amounts

    Use a new sterile syringe each time. Wipe the stopper, draw the calculated volume slowly, and check the syringe markings at eye level. For U-100 insulin syringes, 100 units equals 1 ml.

    • A pen device still depends on the same concentration math. Confirm the cartridge or pen volume before setting units.
    • Keep concentration, draw volume, and date in the research record.

Common mistakes

  • Injecting water directly into the powder instead of down the vial wall.
  • Shaking the vial instead of gently swirling.
  • Skipping alcohol wipes on vial stoppers.
  • Mixing multiple vials at once without a clear reason.
  • Forgetting that U-100 syringe units are volume units, not milligrams or micrograms.
  • Storing a reconstituted vial at room temperature.
