The Saint Petersburg Institute of Bioregulation and Gerontology
NPCRIZ peptide products are the result of long-term research at the Saint Petersburg Institute of Bioregulation and Gerontology (also known as the Prof. Vladimir Khavinson Institute). The institute was founded in 1992 on the initiative of Prof. Vladimir Khavinson (1946–2024).
Over 30+ years of activity, the institute has published more than 800 scientific papers, obtained 200+ patents, and conducted clinical trials with thousands of patients.
Peptide bioregulators — the scientific basis
Peptide bioregulators (Cytomaxes and Cytogens) are short peptide chains (typically 2–4 amino acids) that recognize target tissues through a molecular "lock-and-key" mechanism. Selectivity is the key property of these peptides: Libidon peptides act only on prostate cells, Vladonix only on thymus cells.
Unlike hormones or medications, peptides act on natural regulatory processes, helping damaged or aged cells regain functional activity. The dose is measured in micrograms, so risk and side-effect profiles are low.
