Vesilute vs DSIP

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

Anti-Aging & Longevity
Vesilute
Sleep OptimizationCognitive Enhancement
DSIP
Summary
Vesilute is a tetrapeptide bioregulator (Lys-Glu-Asp-Leu) developed by Professor Vladimir Khavinson, tissue-specific for the retina and visual system. It supports retinal cell function, promotes normalization of photoreceptor protein synthesis, and is studied for age-related macular degeneration (AMD), retinal aging, and vision preservation in the elderly.
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
Short (minutes); sustained gene-regulatory effects
~30–60 minutes; however downstream sleep effects last 4–6 hours
Admin Route
SubQ, Oral

Key Benefits
  • Supports retinal photoreceptor cell function and survival
  • May slow progression of age-related macular degeneration
  • Reduces retinal cell apoptosis from oxidative stress and aging
  • Anti-aging effects on retinal pigment epithelium
  • Potential support in diabetic retinopathy management
  • Preserves visual acuity with aging
  • Complementary to lutein, zeaxanthin, and NAD+ in ocular health protocols
  • 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
  • Generally well tolerated
  • Mild injection site reactions
  • No significant ocular adverse events reported at standard doses
  • Generally well tolerated
  • Mild grogginess next morning at higher doses
