DSIP
Summary
Cerebrolysin is a porcine brain-derived neuropeptide complex that mimics the action of endogenous neurotrophic factors (BDNF, NGF, GDNF, NT-3). It promotes neurogenesis, neuroprotection, and synaptic plasticity, and is approved in many countries for stroke, traumatic brain injury, and Alzheimer's disease.
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.

~30–60 minutes; however downstream sleep effects last 4–6 hours
Admin Route
IV, IM
SubQ, IV, Intranasal
Research
Typical Dose
5–10 mL
100–400 mcg
Frequency
Daily for 10–20 days
Once nightly
Key Benefits
  • Promotes neurogenesis and synaptic plasticity
  • Approved for stroke rehabilitation (accelerates recovery)
  • Alzheimer's disease: slows progression and improves cognition

  • Enhances memory and executive function
  • Neuroprotection against oxidative stress and excitotoxicity
  • Anti-amyloid and anti-tau effects
  • Mood improvement and reduced anxiety
  • 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
