Summary
Testagen is a tetrapeptide bioregulator (Lys-Glu-Asp-Gly) developed by Professor Vladimir Khavinson, tissue-specific for the testes. It supports Leydig cell function, normalization of testosterone biosynthesis, and spermatogenic activity. Testagen is used in men's health protocols for age-related testosterone decline, male fertility support, and testicular anti-aging.
Pinealon is a synthetic tripeptide (Glu-Asp-Arg) developed by the St. Petersburg Institute of Bioregulation, designed to penetrate the blood-brain barrier and exert neuroprotective, neurogenic, and anti-aging effects by regulating pineal gland and brain cell function.
Half-Life
Short (minutes); sustained gene-regulatory effects
Short (peptides rapidly degraded), but epigenetic/gene regulatory effects persist

Key Benefits
  • Supports endogenous testosterone synthesis via Leydig cell normalization
  • Promotes spermatogenesis and sperm quality
  • Anti-aging effects on testicular tissue
  • May attenuate age-related testosterone decline
  • Mechanistically distinct from TRT — does not suppress HPG axis
  • Useful adjunct to Gonadorelin and Kisspeptin-10 in male hormonal protocols
  • Supports male fertility without exogenous hormone replacement
  • Neuroprotection against oxidative stress and hypoxia
  • Promotes neuronal regeneration and repair
  • Improves memory and cognitive function
  • Enhances sleep quality via melatonin regulation
  • Anti-aging effects on brain cells
  • May slow cognitive decline in neurodegeneration
  • Improves cerebrovascular circulation
  • Reduces neuroinflammation
Side Effects
  • Generally well tolerated
  • Mild injection site reactions
  • No significant endocrine disruption reported at standard doses
  • Excellent safety profile in clinical use
  • Rare: mild drowsiness
  • Transient mild headache at initiation
  • Injection site reaction (SC)
