Melanotan II vs DSIP

Side-by-side comparison of key properties, dosing, and research.

Sexual Health & Libido
Melanotan II
Sleep OptimizationCognitive Enhancement
DSIP
Summary
Melanotan II is a synthetic analog of alpha-melanocyte-stimulating hormone (α-MSH) that stimulates melanin production (skin tanning), suppresses appetite, and enhances sexual function. It is not FDA-approved and has significant safety concerns including mole changes and cardiovascular effects.
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.

Key Benefits
  • Promotes skin tanning and melanin production
  • Reduces UV exposure needed to tan
  • Enhances libido and sexual function
  • May suppress appetite
  • Faster, deeper tan development
  • Longer-lasting tan maintenance
  • Potential photoprotective effects
  • 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
Side Effects
  • Nausea (very common, especially in first days)
  • Facial flushing
  • Spontaneous erections in men
  • Darkening or changes in existing moles (monitor closely)
  • +3 more
  • Generally well tolerated
  • Mild grogginess next morning at higher doses
