Hormonal

The weight loss efficacy of Tirzepatide is dose-dependent and increases with longer duration of treatment.

If you are taking Tirzepatide, sticking with the treatment for a longer duration and reaching the higher maintenance doses (like 15mg) will result in more significant weight loss than lower doses. The drug's effectiveness scales with the dose.

These reductions were even greater, especially with higher doses and duration of Tirzepatide... subgroup results showed that changes in weight loss following subcutaneous Tirzepatide at a dose of 15 mg (WMD: -13.02 kg...) were higher compared to other doses (10 mg... 5 mg...)
