Testagen
Summary
Pancragen is a tripeptide bioregulator (Lys-Glu-Asp) developed by Professor Vladimir Khavinson, tissue-specific for the pancreas. It supports the function of both exocrine and endocrine pancreatic cells, promotes normalization of insulin secretion from beta cells, and may offer protective effects against pancreatic aging and diabetic progression.
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.

Key Benefits
  • Supports pancreatic beta cell function and insulin secretion
  • May improve glucose metabolism in early metabolic dysfunction
  • Protective effects on exocrine pancreatic tissue
  • Anti-aging effects on pancreatic cells
  • Potential support in type 2 diabetes management alongside standard care
  • Reduces pancreatic cellular apoptosis from metabolic stress
  • Complementary to GLP-1 agonists in metabolic protocols
  • 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
Side Effects
  • Generally well tolerated
  • Mild injection site reactions
  • No significant hypoglycemic events reported at standard doses as monotherapy
  • Generally well tolerated
