Tesofensine

NS2330 · tesofensine oral

Oral triple monoamine reuptake inhibitor (dopamine, norepinephrine, serotonin) studied for obesity. Not a peptide. Not a GLP-1. Not reconstitution math. Sometimes discussed next to incretins as a plateau adjunct — that is pharmacology folklore, not a labeled stack.

How it works

Tesofensine (NS2330) is an oral inhibitor of dopamine, norepinephrine, and serotonin reuptake studied for weight loss. It is not a GLP-1, not a peptide, and not something you put in the reconstitution calculator.

People search it next to incretins as a “plateau” adjunct. That is a pharmacology conversation, not a labeled stack and not a reason this site invents a combined protocol.

Who it is for

Weight (oral non-peptide)

Moderate

Real trial history. Clinician and jurisdiction decide legality and monitoring.

Peptide reconstitution

Low

Wrong category entirely.

Safety & Considerations

Central monoamine agent. Heart rate, blood pressure, mood, and sleep can move. Not for casual polypharmacy next to stimulants or other serotonergic drugs without a clinician. Not a peptide burn/PIP story.

Regulatory & Legal Status

Limits of current evidence

  • Not a peptide. Calculator math does not apply.
  • Not FDA-approved as a US obesity drug on this leaf’s default reading — jurisdiction matters.
  • Monoamine agents carry cardiovascular and psychiatric monitoring stories. This page is not a prescribing guide.
  • Stacking folklore with tirzepatide is not a labeled protocol on this site.

Verdict

Tesofensine is an oral monoamine reuptake obesity molecule, not a peptide and not a GLP-1. Use it as an identity leaf. Do not invent a reconstitution chart or a labeled incretin stack.

Interactions & Contraindications

Central monoamine agent. Heart rate, blood pressure, mood, and sleep can move. Not for casual polypharmacy next to stimulants or other serotonergic drugs without a clinician. Not a peptide burn/PIP story.

Frequently Asked Questions

Is tesofensine a peptide?
No. It is a small-molecule monoamine reuptake inhibitor.
Can I mix it with tirzepatide?
This site will not publish a stack protocol. Incretin + monoamine is a clinician problem, not a calculator problem.
