Tesofensine- Summary
- DSIP is an endogenous neuropeptide originally isolated from rabbit cerebrospinal fluid that induces delta-wave (deep) sleep. It also modulates stress response, cortisol regulation, and LH secretion, making it valuable for sleep optimization and stress management.
- 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.
- Half-Life
- ~30–60 minutes; however downstream sleep effects last 4–6 hours
- 8-10 days (exceptionally long; accumulates over weeks)
- Admin Route
- SubQ, IV, Intranasal
- Oral

- Typical Dose
- 100–400 mcg
- 0.25-0.5 mg per day
- Frequency
- Once nightly
- Once daily
- Key Benefits
- Induces and deepens delta-wave (slow-wave) sleep
- Reduces cortisol and normalizes HPA axis
- Improves sleep quality in insomnia patients
- Anti-stress and anxiolytic effects
- May improve opiate/alcohol withdrawal symptoms
- Analgesic properties through opioid modulation
- Antioxidant and neuroprotective effects
- 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
- Side Effects
- Generally well tolerated
- Mild grogginess next morning at higher doses
- Rare: hypotension
- Potential for altered dream patterns
- Elevated heart rate and blood pressure (sympathomimetic)
- Dry mouth
