What is Tesofensine?

Tesofensine was originally developed for Parkinson's and Alzheimer's disease but found to have significant weight loss effects, leading to its development as an anti-obesity agent. It acts as a triple monoamine reuptake inhibitor and is currently in phase III clinical trials for obesity. While unapproved by the FDA, it remains investigational with concerns about cardiovascular effects and insomnia.

Primary Benefits

Promotes significant weight loss. Suppresses appetite. Improves metabolic markers.

How It Works

Tesofensine inhibits the reuptake of dopamine, norepinephrine, and serotonin by blocking their transporters, thus increasing neurotransmitter levels. This action in the hypothalamus suppresses appetite and increases energy expenditure, aided by silencing of GABAergic neurons that typically promote feeding behavior.

Safety Tips

Precautions reported in community discussions and literature. This is not a complete list.

  • 1.DON'T combine Tesofensine with MAOIs, SSRIs, SNRIs, or stimulants.
  • 2.AVOID use in individuals with cardiovascular disease or uncontrolled hypertension.
  • 3.DON'T take in the evening due to risk of insomnia.
  • 4.NEVER use if you have a history of serotonin syndrome.
  • 5.DON'T ignore regular cardiovascular monitoring while using Tesofensine.
  • 6.DON'T start with a high dose; begin with the lowest effective dose to assess tolerance.
  • 7.NEVER use products from unregulated sources without proper verification.

Who Should NOT Use

  • Cardiovascular disease
  • Uncontrolled hypertension
  • Concurrent MAOI use

Frequently Asked Questions

Common questions about Tesofensine

How long until I see effects?

You may notice appetite reduction within the first week of using Tesofensine, with significant weight loss typically starting in weeks 2-4.

What time of day should I take it?

Tesofensine should be taken in the morning to minimize insomnia and ensure even blood levels.

How can I minimize side effects?

To minimize side effects of Tesofensine, start with a low dose and avoid taking it in the evening to reduce the risk of insomnia.

Does tolerance develop?

Tolerance to the anorexigenic effects of Tesofensine may develop, although weight loss effects tend not to diminish over time.

How should I store it?

Tesofensine should be stored at room temperature, protected from moisture.

Do I need to cycle it?

There are no standard recommendations for cycling Tesofensine, but due to its long half-life, consistent daily dosing is less critical.

Can I combine it with other peptides?

There's insufficient data on combining Tesofensine with peptides like Semaglutide, so caution is advised.

Safety Tips

  • Always consult a licensed medical professional for dosing and reconstitution instructions.
  • Always double check your units. Mixing up mg and mcg can be very dangerous.
  • Make sure to select your syringe type. U-100 and U-50 syringes have different units.
  • Ensure you're not adding more BAC than your vial can hold. Most vials have maximum capacities listed.
