Tesofensine

Triple monoamine reuptake inhibitor

Tesofensine

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.
