Retatrutide

A triple-agonist peptide that activates GLP-1, GIP, and glucagon receptors to improve metabolism and weight control.

Quickstart Highlights

Retatrutide 10mg dosage protocol is designed to support metabolic improvements and assist in weight management through once-weekly subcutaneous injections.

  • Typical starting dose between 0.5 – 2 mg per week

  • Once-weekly injection schedule for ease of use

  • Gradual titration to manage side effects and improve tolerance

  • Reconstitute to a practical concentration for accurate dosing

  • Storage: Lyophilized: store at room temperature in a dark spot or in its box; after reconstitution, refrigerate at 2–8 °C (35.6–46.4 °F). Avoid repeated freeze–thaw cycles.

Ideal for individuals not exceeding 4 mg per week. Reconstitute with 2 mL to create a 5 mg/mL solution. Frequency: Inject once weekly subcutaneously.

  • Draw 2.0 mL of bacteriostatic water with a sterile syringe.

  • Inject the water slowly into the vial, aiming against the vial wall to avoid foaming.

  • Gently swirl or roll the vial until the powder fully dissolves (do not shake vigorously).

  • Refrigerate at 2–8 °C (35.6–46.4 °F), protected from light.

Recommended for higher doses (8–10 mg weekly). Reconstitute with 1 mL to create a 10 mg/mL solution. Frequency: Inject once weekly subcutaneously.

  1. Draw 1.0 mL of bacteriostatic water with a sterile syringe.

  2. Inject the water slowly into the vial, aiming against the vial wall to avoid foaming.

  3. Gently swirl or roll the vial until the powder fully dissolves (do not shake vigorously).

  4. Refrigerate at 2–8 °C (35.6–46.4 °F), protected from light.

Supplies Needed

Plan based on an 8–16 week daily protocol with gradual titration.

  • Peptide Vials (Retatrutide, 10mg each):

    • 8 weeks ≈ 1 vials

    • 12 weeks ≈ 2 vials

    • 16 weeks ≈ 3 vials


  • Insulin Syringes (U‑100):

    • Per week: 1 syringe

    • 8 weeks: 8 syringes

    • 12 weeks: 12 syringes

    • 16 weeks: 16 syringes


  • Bacteriostatic Water (1*10 mL bottle): Use ~2.0 mL per vial for reconstitution.


  • Alcohol Swabs: One for vial stopper + one for skin per injection.

    • Per week: 2 swabs

    • 8 weeks: 16 swabs

    • 12 weeks: 24 swabs

    • 16 weeks: 32 swabs

Protocol Overview

Concise summary of the once‑daily regimen.

  • Goal: Promote weight loss and metabolic improvement

  • Schedule: Weekly subcutaneous injections for 8–12 weeks (or longer)

  • Dose Range: 0.5 mg to 2 mg weekly, with potential escalation up to 12 mg

  • Reconstitution: Use ~2 ml for easy measuring (5 mg/ml concentration)

  • Storage: Lyophilized vials frozen; reconstituted solution refrigerated; avoid refreezing.

Dosing Protocol

Suggested once-weekly injection approach for effective titration.

  • Weekly Dose: Start at 0.5 mg; gradually increase as tolerated

  • Frequency: Inject once per week subcutaneously

  • Cycle Length: 8–12 weeks (extend as needed for maintenance)

  • Maximum Dose: Can escalate to 12 mg weekly, depending on goals

  • Timing: Any time of day; consistency is key

‼️ Important Notes

Practical considerations for consistency and safety.

  • Use a new sterile insulin syringe for each injection and dispose of needles in a proper sharps container.

  • Rotate injection sites (abdomen, thigh, upper arm) to minimize local irritation or tissue changes over time.

  • Inject slowly and steadily; after injection, wait a few seconds before withdrawing the needle to prevent leakage.

  • Track progress throughout the protocol, adjusting dosage as recommended.

General subcutaneous injection guidance (for educational purposes).

  • Clean the vial’s rubber stopper and your chosen injection site with alcohol swabs; let them air-dry.

  • Using an insulin syringe, pinch a fold of skin and insert the needle at a 45–90° angle into the subcutaneous tissue (fat layer).

  • Do not aspirate (no need to pull back on the plunger) for subcutaneous injections. Inject the peptide slowly and steadily.

  • After injection, dispose of the syringe safely. Rotate injection sites (abdomen, thighs, upper arms) to prevent irritation or scar tissue build-up.

Potential Benefits & Side Effects

Retatrutide is a multi-receptor agonist that helps regulate appetite and metabolism.

  • Hormone Pathways: Activates GLP-1, GIP, and glucagon receptors

  • Metabolic Support: Assists in lowering body weight and improving metabolic markers

  • Targets multiple pathways to enhance energy balance and satiety

Most users observe enhanced weight management, though results can vary.

  • Supports healthier metabolic function

  • Aids in body weight reduction strategies

  • Possible mild side effects include nausea, dizziness, or GI discomfort

  • Rarely, injection-site irritation or headaches could occur
