Epithalon vs DS5

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

Anti-Aging & Longevity
Epithalon
Sleep Optimization
DS5
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.
DS5 is a synthetic variant of the delta sleep-inducing peptide (DSIP), a nonapeptide originally isolated from rabbit cerebrospinal fluid during slow-wave sleep. Like DSIP, DS5 is explored for sleep optimization, stress modulation, and circadian rhythm normalization, with proposed improvements in potency or stability over the parent molecule.

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
  • Promotes delta-wave (deep) sleep and improves sleep quality
  • May reduce sleep onset latency
  • HPA axis modulation for stress reduction
  • Non-addictive sleep support without tolerance development
  • Potential circadian rhythm normalization
  • Explored for insomnia, chronic stress, and PTSD-related sleep disturbance
Side Effects
  • Injection site irritation (mild)
  • Temporary sleep changes during cycle (usually improves)
  • Rare: fatigue
  • Generally well-tolerated in research subjects
  • Possible morning grogginess at higher doses
  • Mild blood pressure fluctuations reported with DSIP
  • Limited human safety data for DS5 specifically
