Tesofensine
Originally for Parkinson's/Alzheimer's, found to cause major weight loss. Boosts serotonin, dopamine, and norepinephrine simultaneously, crushing appetite and revving metabolism.

Top benefits
Week 1–2
Appetite suppression noticeable within days. Increased energy and motivation. Possible mild stimulant effects — heart rate may increase slightly.
Week 3–6
Significant weight loss (triple monoamine reuptake inhibition driving appetite suppression and thermogenesis). Improved mood and motivation from dopamine effects.
Week 8+
Substantial weight loss (10%+ body weight in trials). Sustained appetite control. Cardiovascular parameters need ongoing monitoring.
Common Side Effects
Scientific Overview
Tesofensine is a triple monoamine reuptake inhibitor (5-HT, NE, DA). Phase 2 obesity trials showed 4.5-10.6% weight loss over 24 weeks via central appetite suppression and thermogenesis. Requires cardiovascular monitoring due to modest HR and BP increases.
Dosing
0.25-0.5 mg by mouth daily. Start at the lower dose. Cycle for 12-24 weeks.

Stacks Well With
Semaglutide
Active ingredient in Ozempic/Wegovy. Mimics GLP-1 to signal fullness and slow gastric emptying. STEP trials showed 14.9% weight loss at 68 weeks.
5-Amino-1MQ
Small molecule blocking NNMT, an enzyme that slows metabolism. Increases NAD+ production and energy expenditure. Promotes fat loss and may fix metabolic issues.
