🚨 CRITICAL WARNING: Tesofensine is a Schedule 4 Prescription-Only medicine in Australia. It acts as a powerful central nervous system stimulant. It is classified by WADA under Section S6 (Stimulants) and is strictly prohibited In-Competition. Because it has a very long half-life (9 days), athletes must stop taking it weeks before a drug test to avoid a positive result.
✅ Executive Summary: Key Takeaways for Tesofensine
- What is it? A serotonin-noradrenaline-dopamine reuptake inhibitor (SNDRI) originally developed for Alzheimer’s/Parkinson’s that turned out to be arguably the most potent weight loss drug in history.
- Best Use: Crushing appetite completely and increasing resting energy expenditure.
- The “Magic”: It doesn’t just stop hunger (Serotonin); it boosts motivation (Dopamine) and energy (Noradrenaline), creating a “feel good” weight loss experience.
- The Result: Clinical trials showed almost double the weight loss of Semaglutide in head-to-head comparisons (though trials vary).
- Cost Estimate: $300 – $450 AUD per course.
The Science Behind “The Triple Threat”
Most antidepressants work on one neurotransmitter (usually Serotonin – SSRIs). Most ADHD meds work on two (Dopamine/Noradrenaline).
Tesofensine works on all three.
It is a “Triple Reuptake Inhibitor.” This means it stops your brain from re-absorbing these three critical chemicals, keeping their levels high in your synaptic gaps.
- Noradrenaline: Increases metabolic rate and fat oxidation.
- Dopamine: Controls the “reward” center. By keeping dopamine high, you don’t crave sugar or junk food to feel good.
- Serotonin: Controls satiety. It tells your brain “I am full.”
This unique triad creates a perfect storm for weight loss. In the famous “TESO” clinical trials, patients on a 0.5mg dose lost an average of 10% of their body weight in 24 weeks essentially by accident (since the drug was being tested for brain health, not obesity). When diet was controlled, the results were even higher.
Unlike Ozempic, which works on the gut (slowing digestion), Tesofensine works entirely on the brain. It changes your relationship with food.
🧠 Did You Know?
Tesofensine has a massive half-life of 9 days. This is incredibly rare for an oral drug. It means that if you miss a dose, it doesn’t matter—the drug is still working in your system. It also means it takes about 2-3 weeks to reach “steady state” concentration in your blood.
Who Is Talking About Tesofensine?
- Dr. Andrew Huberman: Has discussed dopamine pathways extensively, noting that agents which elevate dopamine (like Tesofensine) are effective for weight loss because they remove the “seeking” behavior associated with food addiction.
- Ben Greenfield: The biohacker lists Tesofensine as his top “oral” alternative to GLP-1 agonists. He prefers it because it doesn’t cause the muscle loss or nausea associated with Ozempic.
- Peptide Clinics: In Australia, Tesofensine is rapidly becoming the “upsell” to Semaglutide. Clinics often prescribe it to patients who have plateaued on injections or who simply cannot tolerate the nausea of GLP-1s.

Real World Applications: Why Australians Use It
The “Ozempic Hater”
Many patients try Ozempic and quit because they can’t stand the constant nausea or the needle anxiety.
- The Goal: Tesofensine offers similar appetite suppression but via a different mechanism. Instead of feeling “sick full,” they just feel “not hungry.” It’s a cleaner feeling for many.
The “Low Energy” Dieter
Traditional diets make you tired.
- The Goal: Because Tesofensine boosts noradrenaline and dopamine, it acts as a functional stimulant. Users report feeling more productive and focused at work while dieting, rather than lethargic.
The How-To Guide for Using Tesofensine Correctly
Tesofensine is potent. The difference between a “miracle dose” and a “panic attack dose” is small.
The Protocol: Start Low
- Format: Capsules.
- Dosage:
- Starting: 250mcg (0.25mg) daily for the first 2 weeks.
- Standard: 500mcg (0.50mg) daily thereafter.
- Max: Never exceed 1mg. The side effects (heart rate/insomnia) become unbearable.
- Timing: Take it first thing in the morning.
- Why? It is a stimulant. If you take it at dinner, you will not sleep.
- Cycle: It can be taken for 6-12 months safely, but many users cycle it (3 months on, 1 month off) to reset their adrenal receptors.
The “Half-Life” Rule
Because it stays in your system for 9 days, you don’t need to double up if you miss a dose. In fact, if you feel “too wired,” you can switch to taking it every second day (EOD). This is a very common and effective protocol to save money and reduce side effects.
⚡ Don’t Forget To…
Check your heart rate. Tesofensine will raise your resting heart rate by about 4-8 beats per minute. If you already have tachycardia or high blood pressure, you must monitor this closely.
Costs, Legality & Troubleshooting
Cost Analysis
It is a premium compound.
- Price: A bottle of 30-60 capsules costs $300 – $450 AUD.
- Daily Cost: At $10+ per day, it is an investment.
- Value: However, because many users only need to take it every second day (due to the long half-life), one bottle can last 2 months, making it competitive with Semaglutide.
Troubleshooting: “I can’t sleep”
Insomnia is the #1 side effect.
- The Fix:
- Take it earlier (6 AM).
- Switch to every second day dosing.
- Lower the dose to 250mcg.
- Stack it with Magnesium or L-Theanine at night to calm the nervous system.
Troubleshooting: “Dry Mouth”
Common with noradrenaline boosters.
- The Fix: Drink more water. Use a dry mouth spray if needed. It usually subsides after 2 weeks.
The Dealbreaker Safety Check
Side Effects
- Jitters/Anxiety: If you are prone to panic attacks, Tesofensine might trigger them. It is stimulating.
- Heart Palpitations: You will feel your heart beating harder during exercise.
- Mood Swings: Because it plays with dopamine/serotonin, coming off the drug can sometimes cause a temporary mood dip. Taper off slowly.
Contraindications
- Antidepressants: Do NOT take Tesofensine if you are on SSRIs (Lexapro/Zoloft) or MAOIs. Since both drugs increase serotonin, combining them can lead to Serotonin Syndrome, which is potentially fatal. You must choose one or the other.
Frequently Asked Questions
Is it better than Duromine?
Pharmacologically, yes. Duromine (Phentermine) mainly releases noradrenaline (stress/energy). Tesofensine releases noradrenaline PLUS dopamine and serotonin. This makes Tesofensine stronger for appetite suppression and “mood,” with generally less “jitteriness” than Phentermine.
Can I stack it with 5-Amino-1MQ?
Yes. This is the ultimate “Oral Fat Loss” stack.
- Tesofensine: Stops the hunger (Input).
- 5-Amino-1MQ: Increases the burn (Output).
- Result: Rapid fat loss without needles.
Does it burn muscle?
Not directly. However, because it kills your appetite so effectively, you might accidentally starve yourself. If you eat 500 calories a day, you will lose muscle. You must force-feed protein (shakes/bars) to protect your lean mass.
Will I fail a drug test?
YES. WADA bans stimulants. Tesofensine will show up. Because of the 9-day half-life, you need to be off it for at least 6-8 weeks before a tested competition to be safe.
Is it a peptide?
No. It is a synthetic small molecule (a chemical drug). But like 5-Amino-1MQ, it is sold almost exclusively by peptide clinics in the “Metabolic” category.
