What does the evidence say about Tesofensine?

Human weight-loss trials exist, but safety questions and the absence of FDA approval remain important.

What are the risks and side effects of Tesofensine?

• Not approved for human use. Products sold online as "research chemicals" are not made to drug standards, so identity, purity, sterility and dose are unverified.
• It can increase heart rate and blood pressure.
• Its neurotransmitter effects create interaction concerns with antidepressants and stimulants.
• Calling it a peptide is chemically incorrect.

What should you ask a clinician about Tesofensine?

• Could my medications interact with a drug affecting serotonin, dopamine and norepinephrine?
• Which approved weight-loss medicines fit my cardiovascular risk?

These save with the compound when you add it to My Journal, so they’re on the printout for your visit.

Where can I get Tesofensine?

Tesofensine is not approved for human use, so DiscoverMedica links to no seller.

We don’t link to sellers of research-only compounds. Products sold “for research use only” are not made for people and are not held to pharmaceutical quality standards.
