Pancragen vs PE-22-28

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

Anti-Aging & Longevity
Pancragen
Cognitive Enhancement
PE-22-28
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.
PE-22-28 is a synthetic analog of spadin derived from sortilin, designed to block TREK-1 potassium channels with rapid-onset antidepressant and neurogenic effects. It shows fast-acting depression relief (within 24 hours) and promotes hippocampal neurogenesis.
Half-Life
Short (minutes); sustained gene-regulatory effects
Relatively short; CNS effects may persist due to neurogenic mechanisms
Admin Route
SubQ, Oral
SubQ, Intranasal
Research
Typical Dose
10 mg per day
200–400 mcg
Frequency
Daily for 10–30 days
Once daily
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
  • Rapid-onset antidepressant effects (within 24 hours)
  • Promotes hippocampal neurogenesis
  • Improves cognitive performance and memory
  • Reduces anxiety and depressive behavior
  • Novel mechanism — does not act on serotonin/dopamine/GABA receptors directly
  • May help treatment-resistant depression
  • Neuroprotective effects
Side Effects
  • Generally well tolerated
  • Mild injection site reactions
  • No significant hypoglycemic events reported at standard doses as monotherapy
  • Generally well tolerated in animal models
  • Limited human data available
  • Possible mild headache or transient mood changes at initiation
  • Injection site reactions (SC)
