The Novusyn Research retatrutide reconstitution calculator is a laboratory math tool for investigators preparing lyophilized retatrutide (LY3437943) research vials. Enter the vial mass (mg), the bacteriostatic water volume added (mL), and a target mass per draw (mg); the tool returns the resulting concentration in mg/mL, the draw volume in mL, and the equivalent insulin-syringe units. All outputs are theoretical calculations for in-vitro research planning. The tool is not medical instruction and not a dosing schedule. Access is restricted to users 21+ per our compliance policy.
Retatrutide is a triple agonist of the GIP, GLP-1, and glucagon receptors under investigation in the TRIUMPH and related programs. Research vials are typically supplied lyophilized at 5–30 mg. Reference concentrations: 10 mg + 1.0 mL = 10 mg/mL; 10 mg + 2.0 mL = 5 mg/mL; 20 mg + 2.0 mL = 10 mg/mL; 30 mg + 3.0 mL = 10 mg/mL. Bacteriostatic water is the standard reconstitution solvent; store refrigerated and protected from light.
