Pancragen vs Selank

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

Anti-Aging & Longevity
Pancragen
Cognitive Enhancement
Selank
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.
Selank is a synthetic heptapeptide analog of tuftsin developed in Russia. It is a potent anxiolytic that reduces anxiety and enhances cognitive function without sedation or addiction. It is approved for clinical use in Russia for anxiety disorders.
