Retatrutide Dosing Chart in Units
Convert Retatrutide mg dose to insulin syringe units across common compounded concentrations. Use the calculator above for non-standard concentrations.
| Dose (mg) | 2.5 mg/mL conc. | 5 mg/mL conc. | 10 mg/mL conc. |
|---|---|---|---|
| 1 mg | 40 units | 20 units | 10 units |
| 2 mg | 80 units | 40 units | 20 units |
| 4 mg | 160 units | 80 units | 40 units |
| 6 mg | 240 units | 120 units | 60 units |
| 8 mg | 320 units | 160 units | 80 units |
| 12 mg | 480 units | 240 units | 120 units |
How to read this: "Concentration" is how much Retatrutide is in 1 mL of reconstituted solution. 100 units = 1 mL on a standard insulin syringe. Always confirm your prescribed dose with your healthcare provider before injection.

Frequently Asked Questions
What is the standard Retatrutide dose?
Titration: start 2mg weekly for 4 wks, then titrate up 2mg every 4 wks to 8–12mg maintenance. Research-only; not FDA-approved. Track glucose, ApoB, LFTs monthly.
How do I reconstitute Retatrutide?
Add 2mL of bacteriostatic water to a 12mg vial of Retatrutide to get a concentration of 6000 mcg/mL. This gives 2000mcg per 33 units on a 100-unit insulin syringe.
What blood markers should I track while running Retatrutide?
Common biomarkers tracked alongside Retatrutide protocols include HbA1c, Fasting glucose, ApoB, Triglycerides, LFTs, Weight, Heart rate (monitor - can increase). Establishing a baseline panel before starting and re-drawing labs at consistent intervals lets you measure changes against your own reference point, generic lab ranges are less informative than your personal trend over time. MyProtocolStack tracks each of these biomarkers in the context of your active Retatrutide protocol.
