Retatrutide — ≥98% Research Peptide
The World's First Triple-Action Metabolic Peptide
First peptide that simultaneously activates GIP, GLP-1, AND glucagon receptors. The third target adds direct energy burning and fat breakdown.
Research Applications & Benefits
- First-ever triple receptor agonist
- Enhanced energy expenditure via glucagon
- Superior metabolic effects
- Cutting-edge hormonal synergy
Doses Used in Published Studies
Literature values for laboratory reference only — not dosing guidance.
| Model | Dose | Route | Duration | Ref |
|---|---|---|---|---|
| Human, adults with obesity (Phase 2) | 1, 4, 8 or 12 mg (escalated from 2 or 4 mg) | Subcutaneous, once weekly | 48 weeks | [1] |
Laboratory Handling
- 5mg vial + 2 mL solvent = 2.5 mg/mL
- Store lyophilized powder sealed at −20 °C, protected from light and moisture; allow the vial to reach room temperature before opening to limit condensation.
- Reconstitute with sterile or bacteriostatic water, adding solvent slowly down the vial wall and swirling gently — do not shake.
- Store reconstituted solution at 2–8 °C and use within about 28 days; avoid repeated freeze–thaw cycles by aliquoting if longer storage is needed.
- Record lot number and reconstitution date on every vial so results trace back to the matching Certificate of Analysis.
