What Tesofensine is
An investigational non-peptide weight-loss drug that suppresses appetite by acting on brain neurotransmitters.
Tesofensine is a small-molecule inhibitor of the reuptake of noradrenaline, dopamine, and serotonin, originally studied for Parkinson's and Alzheimer's before its appetite-suppressing effect drew attention. Phase 2 obesity trials showed substantial weight loss.
Mechanism: Blocks reuptake of noradrenaline, dopamine, and serotonin, increasing satiety signaling and reducing food intake.
Regulatory history: Investigational, not FDA-approved
How TGA treats this kind of product
Registers or lists therapeutic goods on the ARTG and schedules substances in the Poisons Standard. Many peptides are Schedule 4 (prescription only), so possession without a prescription and personal importation are restricted even when no product is registered.
The classification above is the The Longevity Archive reading of Therapeutic Goods Administration listings for Tesofensine at the reviewed date, not a legal opinion. Rules change, and importing, prescribing and possessing a compound can each be treated differently. Check the regulator directly before acting on anything here.
