GLP-1 Receptor Agonist Weekly Protocol Guide

Dulaglutide Protocol Guide

✓ Verified dosing (fact-checked against FDA labels / published trials): Dulaglutide (Trulicity), subcutaneous, ONCE WEEKLY. Start 0.75 mg once weekly; may titrate to 1.5 mg after >=4 weeks, then in 1.5 mg increments (3 mg, 4.5 mg) every >=4 weeks; max 4.5 mg/week. Single-dose prefilled pen — fixed dose, not measured in insulin 'units'. Any time of day, with/without food; abdomen, thigh, or upper arm. This supersedes any conflicting figures shown elsewhere on this page; confirm with a licensed provider.

Dulaglutide is a long-acting GLP-1 receptor agonist fused to a modified IgG4 Fc fragment, providing an extended half-life for once-weekly dosing. It is studied for glycemic control and weight management in type 2 diabetes research.

Protocol Overview

Compound
Dulaglutide (Trulicity - Weekly GLP-1 for Weight and T2D Research)
Category
GLP-1 Receptor Agonist
Vial Size
3mg (3,000mcg)
Reconstitution
2mL bacteriostatic water (1.5mg/mL)
Route
Subcutaneous injection
Frequency
Once weekly

Reconstitution Instructions

Using 2mL of bacteriostatic water results in a concentration of 1.5mg/mL. Start at 0.75mg and titrate. Always use sterile techniques.

Materials Needed

  • 3mg Dulaglutide 3mg vial (lyophilized powder)
  • 2mL bacteriostatic water (sterile, preserved with 0.9% benzyl alcohol)
  • Sterile syringe and needle (18-22 gauge for drawing)
  • Alcohol swabs
  • Clean workspace

Step-by-Step Process

  1. Preparation: Allow the Dulaglutide 3mg vial and bacteriostatic water to reach room temperature. Wipe the rubber stoppers of both vials with an alcohol swab.
  2. Draw the Water: Using a sterile syringe, draw up exactly 2mL of bacteriostatic water. Expel any air bubbles.
  3. Inject into Vial: Insert the needle through the rubber stopper at a slight angle, aiming toward the glass wall. Slowly inject the water down the side of the vial to avoid foaming.
  4. Mix Gently: Remove the needle. Gently swirl or roll the vial between your hands. Do not shake vigorously.
  5. Check for Clarity: The solution should be clear once fully reconstituted. Do not use if cloudy.

Administration Guidelines

  • Administer subcutaneously once weekly on the same day each week
  • Start at 0.75mg weekly for at least 4 weeks then may increase to 1.5mg weekly
  • Rotate injection sites between abdomen, thigh, and upper arm
  • Store reconstituted peptide refrigerated at 36-46F (2-8C)
  • Use reconstituted solution within 30 days
  • Never freeze reconstituted peptides
  • Document administration times and observations
