Retatrutide (5mg)
Table of Contents
Quickstart Highlights
Retatrutide 5mg 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
- Store lyophilized in the freezer; reconstituted in the refrigerator
Dosing & Reconstitution Guide
Educational guide for reconstitution and dosing protocol
Standard / Gradual Approach (1 mL = 5 mg/mL)
| PHASE | WEEKLY DOSE (mg) | APPROX. UNITS |
|---|---|---|
| Weeks 1–4 | 0.5 mg | 10 units |
| Weeks 5–8 | 1 mg | 20 units |
| Weeks 9–12 | 2 mg | 40 units |
| Weeks 13–16 (Optional) | 4 mg | 80 units |
Ideal for individuals not exceeding 4 mg per week. Reconstitute with 1 mL to create a 5 mg/mL solution.
- Draw 1.0 mL of bacteriostatic water into a sterile syringe.
- Inject the water slowly along the vial wall to reduce foam.
- Gently swirl—avoid vigorous shaking.
- Store the reconstituted solution at 2–8 °C (refrigerator), protected from light.
Advanced / Aggressive Approach (0.5 mL = 10 mg/mL)
| PHASE | WEEKLY DOSE (mg) | APPROX. UNITS |
|---|---|---|
| Weeks 1–4 | 2 mg | 20 units |
| Weeks 5–8 | 4 mg | 40 units |
| Weeks 9–12 | 8 mg | 80 units |
| Weeks 13–16 (Optional) | 12 mg | 120 units |
Recommended for higher doses (8–12 mg weekly). Reconstitute with 0.5 mL to create a 10 mg/mL solution.
Note: Single 5 mg vial cannot accommodate doses above 5 mg in one injection. Multiple vials or split injections may be required for 8–12 mg dosing.
- Draw 0.5 mL of bacteriostatic water into a sterile syringe.
- Slowly inject the water to reduce foaming.
- Gently roll/swirl the vial—no vigorous shaking.
- Store the reconstituted solution at 2–8 °C (refrigerator), protected from light.
Protocol Overview
A concise summary of this once-weekly 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 ~1 mL for easy measuring (5 mg/mL concentration)
- Storage : Keep lyophilized vials frozen; refrigerate after reconstitution
Dosing Protocol
Suggested once-weekly injection approach for effective titration.
- Weekly Dose : Suggested once-weekly injection approach for effective titration.
- 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
Storage Instructions
Proper storage ensures peptide integrity.
- Lyophilized : Freeze until mixing (−20°C)
- Reconstituted : Refrigerate at 2–8°C
- Avoid repeated freeze-thaw cycles
Suppilies Needed
Ensure you have these on hand for an 8–16 week cycle.
- Peptide Vials :
-
- 8 wks ≈ 2 vials
- 12 wks ≈ 3 vials
- 16 wks ≈ 4+ vials (More if planning higher doses)
- Insulin Syringes :
-
- 8 wks ≈ 8
- 12 wks ≈ 12
- 16 wks ≈ 16
- Bacteriostatic Water : 1× 30ml
- Alcohol Swabs: 1 box
Important Notes
Practical tips to enhance safety and efficacy.
- Always use new, sterile insulin syringes & rotate injection sites.
- Maintain consistency; follow the planned schedule for reliable results.
- Observe for adverse reactions; consult a professional if concerns arise.
- Track progress throughout the protocol, adjusting dosage as recommended.
How This Works
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
Potential Benefits & Side Effects
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
Lifestyle Factors
Complementary strategies for maximum benefit.
- Adopt a nutrient-dense, protein-rich diet
- Incorporate regular exercise and prioritize recovery
- Manage stress levels and aim for adequate sleep
Injection Technique
Simple guidelines for safe daily injections.
- Clean vial rubber stopper & injection site with alcohol swabs
- Insert needle at a 45–90° angle into subcutaneous tissue
- Inject slowly & rotate sites (abdomen, thigh, etc.)
