Carnosine- Summary
- Tesofensine is a triple monoamine reuptake inhibitor (TMRI) that blocks reuptake of serotonin, dopamine, and norepinephrine. Originally developed for Alzheimer's and Parkinson's disease, it was repurposed as a potent weight loss agent after clinical trials demonstrated substantial fat loss via appetite suppression and increased energy expenditure.
- Carnosine is an endogenous dipeptide (beta-alanine + histidine) found in high concentrations in muscle and brain. It is a potent anti-aging molecule with broad spectrum antioxidant, anti-glycation, anti-carbonylation, and metal chelating properties, making it one of the most protective naturally occurring dipeptides.
- Half-Life
- 8-10 days (exceptionally long; accumulates over weeks)
- ~1.5 minutes (rapidly hydrolyzed to beta-alanine and histidine by carnosinase in blood; tissue levels maintained via constant synthesis)

- Typical Dose
- 0.25-0.5 mg per day
- 1,000–2,000 mg
- Frequency
- Once daily
- Once to twice daily with meals
- Key Benefits
- Potent appetite suppression via triple monoamine reuptake inhibition
- Significant weight loss (8-12% body weight in phase II trials at 0.5 mg)
- Increases basal metabolic rate and energy expenditure
- Reduces fat mass preferentially over lean mass
- Potential cognitive benefit via dopaminergic and noradrenergic enhancement
- Longer half-life than sibutramine allows once-daily dosing
- Potent anti-glycation (prevents protein cross-linking/aging)
- Broad-spectrum antioxidant in muscle and brain
- Extends cell lifespan and protects telomeres
- Improves muscle performance and delays fatigue (pH buffering)
- Neuroprotective against Alzheimer's amyloid-beta
- Wound healing acceleration
- Anti-cataract properties (eye health)
- Improves diabetes complications via AGE prevention
