Weekly research phases

Units and volumes recompute from your Step 1 concentration (1 mL BAC → 5.00 mg/mL · 50.0 mcg/unit).

Standard titration

Approved dual GIP/GLP-1 products titrate roughly 2.5 → 5 → 7.5 → 10 → 12.5 → 15 mg once weekly if tolerated. Research powders are not branded pens.

12-week schedule

Tirzepatide 5 mg vials

12 vials

~60 mg mg total peptide over this 12-week schedule at 2.5 mg → 5 mg → 7.5 mg weekly (phase ladder). Each vial holds 5 mg.

Bacteriostatic water

4 × 3 mL or 2 × 10 mL

1 mL BAC per vial × 12 vials = 12.0 mL total. Buy as 4× 3 mL bottles or 2× 10 mL bottles (whichever you stock).

U-100 insulin syringes (100-unit)

16+ syringes

Some doses need more than one 100-unit syringe at your concentration — plan extras and split draws when the math exceeds the barrel.

Alcohol swabs & sharps

~56 swabs · 1 sharps container

Wipe vial stopper and injection site each time. Dispose needles in a proper sharps container.

Reconstitution steps

  1. Allow the lyophilized 5 mg Tirzepatide vial and bacteriostatic water to reach room temperature.
  2. Draw 1.0 mL bacteriostatic water (default for this guide).
  3. Inject BAC slowly down the inner wall of the vial — avoid blasting the powder cake.
  4. Gently swirl or roll until the solution is clear. Do not shake hard (foaming).
  5. Label with recon date and concentration (e.g. "5.0 mg/mL").
  6. Refrigerate at 2–8 °C (35–46 °F), protected from light. Prefer using a reconstituted multi-dose vial within ~28 days with sterile technique.

Storage

Lyophilized

Keep dry powder cold and dark when possible (−20 °C / −4 °F preferred for long-term research stock).

Reconstituted

Refrigerate at 2–8 °C (35–46 °F). Avoid freeze–thaw of the working solution. Prefer finishing within ~28 days.

  • ·Write recon date and BAC volume on the label.
  • ·Protect from light during storage.
  • ·Discard if cloudy, particulates, or odd odor appear after reconstitution.

Protocol notes

  • ·Dual GIP/GLP-1 agonist — titrate slowly for GI tolerability.
  • ·Research powders ≠ Mounjaro/Zepbound pens.
  • ·Research use only.

Research context & considerations

Tirzepatide is FDA-approved as branded products for T2D and chronic weight management. Catalog research vials are a separate unregulated channel.

  • ·GI effects common during titration.
  • ·GLP-1-class label cautions apply.
  • ·Not FDA-approved as a research-vial consumer product.
  • ·Pregnancy out of scope.
