How Weekly Retatrutide Dosage Is Calculated

Weekly Retatrutide dosage represents the specific amount of medication needed to manage blood sugar and weight safely. The tool uses a titration method to balance efficacy with side effects.

Base Dose + (Weight × 0.1) + (BMI × 0.05) + (Comorbidities × 0.08)

Adjustments:

  • Tolerance: Reduce by 30% (poor) or 15% (moderate).
  • Renal Impairment: Reduce by 25%.
  • Final Range: Clamped between 0.5 mg and 12 mg.

First, we determine a base dose depending on your current treatment phase to ensure a safe starting point.

Next, we add small contributions based on your weight and BMI to ensure the drug reaches effective levels in your body.

Finally, the calculator applies safety filters for kidney health and tolerance to ensure the result is safe to take.

What Your Weekly Retatrutide Dosage Means

Your result indicates the exact milligrams you should inject each week to maximize weight loss while minimizing nausea. This number helps you plan your treatment schedule effectively.

Initiation Phase (0.5–2 mg)

This starter dose helps your body adjust to the medication. Focus on managing any mild nausea rather than expecting immediate weight loss.

Escalation Phase (2.5–6 mg)

In this range, appetite suppression becomes noticeable. Drink plenty of water and eat fiber to manage digestion as your dose increases.

Maintenance (6.5–12 mg)

This is the target range for long-term management. Monitor your blood sugar closely if you have diabetes, as hypoglycemia risk rises.
