Tesofensine Benefits

  • Potent appetite suppression, increased metabolic rate, enhanced thermogenesis, improved mood during dieting, reduces food reward-seeking behavior

Macimorelin Benefits

  • diagnostic GH stimulation
  • single oral dose
  • rapid measurable GH response
  • high clinical utility

Tesofensine Dosing

Clinical doses: 0.25-1.0 mg orally once daily. Research typically uses 0.5 mg. Extremely long half-life (8-13 days) means steady-state in 7-10 days.

Macimorelin Dosing

0.5 mg/kg orally as a single dose|fasted testing conditions|serial GH sampling after administration

Tesofensine Side Effects

  • Dry mouth, insomnia, constipation, increased heart rate, elevated blood pressure. Not recommended with uncontrolled hypertension.

Macimorelin Side Effects

  • dysgeusia or taste disturbance
  • nausea
  • headache

Research Overview

Tesofensine

Phase II trials showed 12.8 kg average weight loss at 1.0 mg dose over 6 months. Simultaneously inhibits reuptake of norepinephrine, dopamine, and serotonin, producing appetite suppression and increased thermogenesis.

Macimorelin

Macimorelin has been validated in clinical testing as an oral alternative to injectable GH stimulation tests. Its short-term use makes it a useful translational tool for evaluating pituitary GH reserve.
