How many units is 2 mg of retatrutide?

With a 10 mg vial in 2.0 mL (5 mg/mL), 2 mg equals 0.4 mL — 40 units on a U-100 syringe. 4 mg is 80 units and 6 mg is 120 units, which exceeds a 1 mL barrel and requires either a higher concentration or two draws.

What concentration should I mix retatrutide at?

A 10 mg vial in 2 mL gives 5 mg/mL and keeps early doses easy to read. If your ramp reaches 6 mg or more, mixing the same vial in 1 mL (10 mg/mL) halves the volume so each dose still fits one syringe.

How much total peptide does a 12-week ramp use?

Four weeks at 2 mg (8 mg), four at 4 mg (16 mg) and four at 6 mg (24 mg) totals 48 mg — five 10 mg vials. The Cycle tab calculates this per phase and adds a buffer option.

Research & Reconstitution Literature Summary

Retatrutide is a triple GIP/GLP-1/glucagon receptor agonist studied in published trials using escalating weekly dosing. Vials are supplied lyophilised and reconstituted with bacteriostatic water; 10 mg in 2 mL gives 5 mg/mL. Because trial designs step the dose every few weeks, total mass across a cycle must be summed phase by phase to produce a correct vial count.
