Retatrutide Dosage Guide & Research Calculator
This retatrutide dosage guide summarizes reconstitution math, an embedded concentration calculator, and dose ranges for retatrutide reported in published preclinical and clinical-trial literature, presented purely as research reference. All figures below summarize parameters reported in published preclinical or in-vitro research. They are provided for reference only and are not instructions for human or veterinary administration.

Retatrutide reconstitution math & retatrutide dosage calculator
Reconstituting a lyophilized peptide gives a solution with a known concentration. The formula is simple:
Worked example: Adding 2 mL of bacteriostatic water to a 10 mg vial of retatrutide yields 5,000 mcg/mL. 0.10 mL (10 units on a U-100 insulin syringe) of that solution represents 500 mcg of peptide.

Retatrutide doses reported in published preclinical research
The figures below summarize Retatrutide doses that appear in published animal-model or in-vitro studies. They describe what researchers have used in laboratory settings — they are not human administration protocols and are not dose recommendations.
| Research context | Dose reported | Notes |
|---|---|---|
| Phase 1 trial, weekly | 0.5–12 mg/week | Range explored in published clinical-pharmacology work. |
| Phase 2 trial, weekly | 1, 4, 8, 12 mg/week | Dose levels reported in published trials. |
| Preclinical rodent studies | 10–100 nmol/kg | Subcutaneous ranges in animal-model literature. |
All values are research-context references compiled from published preclinical and in-vitro literature. Retatrutide is supplied for laboratory and research use only.

Retatrutide research dosage — frequently asked questions
How is retatrutide reconstituted for research?+
Lyophilized retatrutide is dissolved in bacteriostatic water. Concentration is calculated as (vial mg × 1000) ÷ diluent mL, giving mcg per mL.
What concentration does 10 mg retatrutide in 2 mL give?+
10 mg in 2 mL of bacteriostatic water yields a 5,000 mcg/mL solution. 0.10 mL (10 units on a U-100 insulin syringe) contains 500 mcg.
What retatrutide doses are reported in published research?+
Published Phase 1 and Phase 2 trials report weekly doses across roughly 0.5–12 mg, with 1, 4, 8, and 12 mg/week as common dose levels in study arms.
Is this retatrutide dosage guide for human use?+
