VIP
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.
VIP is a 28-amino acid neuropeptide with profound anti-inflammatory, vasodilatory, and immunomodulatory effects. It plays a critical role in gut motility, circadian rhythm, and immune tolerance. Used therapeutically for CIRS (Chronic Inflammatory Response Syndrome), MCAS, and inflammatory conditions.
Half-Life
8-10 days (exceptionally long; accumulates over weeks)
~2 minutes in plasma (rapidly degraded by peptidases); intranasal delivery may extend local CNS effects
Admin Route
Oral
Intranasal, SubQ, IV
Research
Typical Dose
0.25-0.5 mg per day
50 mcg (4 sprays of 12.5 mcg each)
Frequency
Once daily
4x 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
  • Potent anti-inflammatory for CIRS and mold illness
  • Improves pulmonary hypertension symptoms
  • Regulates gut motility and IBS symptoms
  • Modulates circadian rhythm and sleep quality
  • Reduces mast cell activation (MCAS)
  • Improves cognitive function in neuroinflammatory conditions
  • Vasodilatory — reduces vascular resistance
