Noopept- 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.
- Noopept is a potent dipeptide-derived nootropic from Russia, structurally related to piracetam but estimated to be 1,000 times more potent by mass. It enhances memory consolidation, learning, and recall while providing neuroprotection via BDNF and NGF upregulation.
- Half-Life
- 8-10 days (exceptionally long; accumulates over weeks)
- ~5–10 minutes but metabolite (CPG) effects last hours
- Admin Route
- Oral
- Oral, Sublingual, Intranasal

- Typical Dose
- 0.25-0.5 mg per day
- 10–30 mg
- Frequency
- Once daily
- 1–2x daily
- 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
- Enhances memory formation and recall
- Improves learning speed and cognitive processing
- Neuroprotective via BDNF/NGF upregulation
- Anxiolytic at low-to-moderate doses
- Improves verbal fluency and information processing
- Antioxidant (reduces oxidative damage in neurons)
- May improve cognitive symptoms of mild cognitive impairment
