What Are Khavinson Bioregulator Peptides? Tissue-Specific Epigenetic Modulators · Khavinson Institute · 40 Years Research · QSC’s Unique Advantage
Khavinson bioregulator peptides are a class of short (2-5 amino acid) tissue-specific peptides developed by Prof. Vladimir Khavinson at the St. Petersburg Institute of Bioregulation and Gerontology. Unlike receptor-specific peptides (GLP-1R agonists, GHS-R1a agonists), bioregulators act epigenetically — modifying gene expression patterns in target tissues to restore youthful transcription profiles. QSC carries the largest catalog of Khavinson bioregulators available outside Russia — 20+ compounds covering every major organ system.
Bioregulator peptides were originally extracted from organ tissue concentrates and their active sequences isolated by the Khavinson Institute. The synthetic versions reproduce the bioactive sequence identified in the natural extract.
Epigenetic mechanism — interact with chromatin-bound proteins → modify histone acetylation and DNA methylation
Tissue specificity — each bioregulator targets the organ tissue from which it was derived
Gene expression restoration — aged cells show restoration toward youthful transcription profiles in treated models
Short sequences — 2-5 amino acids: small enough for potential oral activity in some models (unlike larger research peptides)

Why QSC Stocks the Full Khavinson Catalog
Most Western research suppliers stock only Epitalon from the Khavinson class — because it has the most published English-language data. QSC stocks 20+ Khavinson bioregulators including every tissue-specific peptide in the catalog, all at ≥99% HPLC with Janoshik independent COA. This makes QSC the primary source for comprehensive Khavinson protocol research outside Russia.
Frequently Asked Questions
What are bioregulator peptides?
Short (2-5 AA) tissue-specific peptides by Khavinson Institute acting epigenetically to restore youthful gene expression in aging tissues. Examples: Epitalon (pineal/telomerase), Pancragen (pancreatic), Thymagen (thymic), Cortagen (cerebral cortex).
Does QSC stock all Khavinson bioregulators?
