How to reconstitute Retatrutide

TR8CE uses one simple standard: 0.1 mL of bacteriostatic water per mg. A 5 mg vial takes 0.5 mL of water for a clean 10 mg/mL solution. Larger vials scale the water up to fit the glass.

Units are shown for a U-100 insulin syringe. A common starting dose is 2 mg. At 10 mg/mL, that draws to 20 units on a U-100 insulin syringe.

How Retatrutide works

Activates the GLP-1, GIP, and glucagon receptors at once. The added glucagon arm raises energy expenditure and thermogenesis on top of appetite suppression and improved insulin sensitivity.

Reported side effects

When is Retatrutide taken?

Retatrutide is commonly taken in the morning.

Frequently asked

How much bacteriostatic water do I add to Retatrutide?

Add 0.5 mL of bacteriostatic water to a 5 mg Retatrutide vial for a 10 mg/mL solution.

What is a common Retatrutide dose?

A common Retatrutide starting dose is 2 mg, which at 10 mg/mL draws to 20 units on a U-100 insulin syringe.

How do you reconstitute Retatrutide?

Draw bacteriostatic water into a syringe, inject it slowly down the inside glass of the Retatrutide vial (not onto the powder), and swirl gently until clear. Store refrigerated and use within the common window.
