Metabolic
R-Series (R-10 / R-20 / R-30)
Investigational triple receptor agonist studied at GLP-1, GIP, and glucagon receptors in metabolic research models.
- Classification
- Synthetic peptide, multi-receptor incretin agonist
- Supplied form
- Lyophilized powder, single-use research vial
- Storage
- Lyophilized powder is typically stored refrigerated or frozen and protected from light. Once reconstituted, solutions are generally kept refrigerated and handled under standard laboratory practice.
- Solubility
- Commonly reconstituted with bacteriostatic or sterile water for laboratory preparation.
What the R-Series is
R-Series (Retatrutide) is a synthetic peptide designed to interact with three metabolic hormone receptors simultaneously: GLP-1, GIP, and the glucagon receptor. Its multi-receptor design distinguishes it from single- and dual-agonist peptides that preceded it in the published literature.
Research context
Published work on triple agonists has focused on energy balance, glucose handling, lipid metabolism, and body-composition endpoints in preclinical and clinical investigational settings. Researchers commonly reference it alongside dual GIP/GLP-1 agonists when comparing receptor coverage.
Handling in the laboratory
Supplied lyophilized. Reconstitution volume determines working concentration in mg/mL; the Lucent Life reconstitution calculator performs that conversion, including U-100 syringe unit equivalents, without implying any dosing regimen.
Concentration reference
Working concentration is determined solely by the solvent volume added to the vial. The Lucent Life reconstitution calculator converts vial strength and solvent volume into mg/mL and U-100 syringe units. It performs unit math only and does not recommend any dosing, administration, or frequency.
