L-Carnitine vs Tesofensine
A side-by-side research comparison of L-Carnitine and Tesofensine across mechanism, dosing, half-life, benefits, side effects and research status.
Comparison table
| Attribute | L-Carnitine | Tesofensine |
|---|---|---|
| Full name | L-Carnitine Injectable | Tesofensine (Triple Monoamine Reuptake Inhibitor) |
| Category | Weight Management | Weight Management |
| Status | Supplement / Compounded | Phase 3 Clinical Trial |
| Mechanism | Transports long-chain fatty acids across the inner mitochondrial membrane via the carnitine shuttle, enabling beta-oxidation for ATP production. Also reduces oxidative stress and supports cardiac function. | Blocks presynaptic reuptake of noradrenaline, dopamine, and serotonin in the hypothalamus, enhancing satiety signaling, reducing food reward, and increasing thermogenesis. |
| Molecular weight | 161.20 Da | 329.4 Da |
| Half-life | ~2-3 hours (IM) | 8-10 days |
| Bioavailability | ~100% injectable; ~14-18% oral | High (oral ~93%) |
| Typical dose | 500-2000 mg | 0.25-0.5 mg |
| Frequency | 2-5x per week | Once daily |
| Route | Intramuscular or IV injection | Oral |
