Khavinson Peptide Bioregulators: What Do They Actually Do?

What are Khavinson peptide bioregulators, and what do they actually do? John Garrett examines the Russian research tradition behind organ-derived peptide complexes and synthetic ultrashort peptides. This episode explains the proposed gene-expression mechanism, the claim of tissue specificity, common examples such as Thymalin and Epitalon, the limitations of the human evidence, oral absorption questions, product-quality concerns, safety, and U.S. regulatory status. The science is more interesting than a simple dismissal—but less proven than organ-rejuvenation marketing suggests. This episode is educational and is not medical advice.
