DSIP
Summary
Epithalon is a synthetic tetrapeptide developed from the pineal gland extract Epithalamin by Russian scientist Dr. Vladimir Khavinson. It is one of the most researched longevity peptides, known for activating telomerase and extending telomere length — the molecular hallmarks of cellular aging.
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.
Half-Life

~30–60 minutes; however downstream sleep effects last 4–6 hours
Admin Route
SubQ, Sublingual
SubQ, IV, Intranasal
Research
Typical Dose
5–10 mg total per cycle
100–400 mcg
Frequency
0.5–1 mg daily
Once nightly
Key Benefits
  • Activates telomerase enzyme, extending telomere length
  • May slow cellular and biological aging
  • Regulates melatonin production and circadian rhythms
  • Improves sleep quality
  • Powerful antioxidant properties
  • May reduce incidence of age-related diseases
  • Supports immune system function
  • Studied for cancer prevention properties in animal models
  • 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
  • Injection site irritation (mild)
  • Temporary sleep changes during cycle (usually improves)
  • Rare: fatigue
  • Generally well tolerated
  • Mild grogginess next morning at higher doses
  • Rare: hypotension
  • Potential for altered dream patterns
