Tesofensine
Triple monoamine reuptake inhibitor

Tesofensine is a serotonin–noradrenaline–dopamine reuptake inhibitor studied for significant appetite suppression and weight loss in clinical trials.
- Typical dose
- 250–500 mcg daily
- Half-life
- ~9 days
- Administration
- Oral (capsule/tablet)
- Research status
- Phase III clinical trials
What it is
Tesofensine is a triple monoamine reuptake inhibitor (serotonin, noradrenaline, dopamine) originally developed for neurodegenerative disease. Clinical trials showed pronounced appetite suppression and weight loss.
Why researchers use it
- Strong appetite suppression via monoamine pathways
- Sustained weight-loss effect in Phase II/III trials
- Complementary to GLP-1 stacks (different mechanism)
Dosing protocol (for research)
- Oral capsule/tablet form
- Typical: 250–500 mcg daily
- Long half-life (~9 days) — steady-state builds over 4–6 weeks
- Cycle rather than continuous long-term use in research protocols
Safety notes
- Elevated heart rate, insomnia, dry mouth, mood changes possible
- Avoid combining with SSRIs, MAOIs, or other monoaminergic drugs
- Not appropriate for individuals with cardiovascular or psychiatric conditions
Reconstitution & concentration
Supplied as an oral capsule — no reconstitution required. Typical capsule: 500 mcg.
- Common research dosing: 250–500 mcg daily with gradual titration
- Duration: 8–24 weeks depending on study goals
CNS stimulant activity makes it less tolerable for sensitive populations. Side effects may include insomnia, jitteriness, elevated heart rate, and dry mouth.
Stacks
Appetite Overdrive Stack:
- Retatrutide: 5–10 mg weekly (SubQ)
- Tesofensine: 250–500 mcg daily (oral)
- Duration: 8–12 weeks depending on tolerability
It's described the combination as covering both central and peripheral appetite suppression — 'food noise completely gone'. Not for those sensitive to stimulants; the overlap can be too strong and food intake sometimes drops too low.
