Retatrutide 5mg Dosage Protocol
Preparation, measurement, commonly documented protocol ranges, and storage for a Retatrutide 5mg vial.
1. Preparation and Measurement
Retatrutide 5mg With 1mL of Diluent
Add 1mL of bacteriostatic water to the vial. The resulting concentration is 5mg/mL. On a U-100 syringe, each unit contains 50mcg.
Preparation
- Draw 1mL of bacteriostatic water using sterile equipment.
- Let the liquid run slowly down the inside wall of the vial.
- Gently swirl until dissolved. Do not shake.
- Label with the preparation date and refrigerate.
Check the calculation with the peptide calculator.
2. Commonly Documented Schedule
Route commonly described: subcutaneous in phase 2 research. Frequency: once weekly.
| Period | Documented amount | Measurement |
|---|---|---|
| Weeks 1-4 | 2mg once weekly | 0.4mL / 40 units |
| Weeks 5-8 | 4mg once weekly | 0.8mL / 80 units |
| Weeks 9-12 | 8mg once weekly | 1.6mL / 160 units* |
| Weeks 13+ | 12mg once weekly | 2.4mL / 240 units* |
Vial estimate: One 5mg vial contains approximately 2 administrations at the first listed amount; later rows exceed one vial's total content.
Practical Notes
- The table applies only to this vial prepared with exactly 1mL.
- An asterisk marks measurements above 1mL, which exceed the capacity of a standard 1mL U-100 syringe.
- Some later entries also exceed the total material in one vial and are shown only to preserve the documented schedule comparison.
- Record the amount, date, and preparation used.
3. Supplies Needed
- Retatrutide 5mg vial.
- 1mL of bacteriostatic water per vial.
- Sterile U-100 syringes.
- Alcohol swabs.
- Sharps container.
4. Storage and Handling
- Keep unopened vials cool, dry, dark, and protected from moisture.
- After preparation, refrigerate at 2-8 degrees C.
- Protect from light and avoid repeated freeze-thaw cycles.
- Do not use material with particles, discoloration, or a damaged seal.
5. Research Context
Retatrutide is an investigational triple receptor agonist studied in phase 2 trials. It is not an approved medicine, and later-stage research may use different designs or conclusions.
The table records a phase 2-style escalation for educational comparison. It is not a prescribing schedule or evidence that a laboratory vial is suitable for human use.
