    About NPCRIZ and the institute
  
  
    
      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, the institute has published more than 800 scientific papers, obtained 200+ patents, and conducted clinical trials with thousands of patients worldwide.
      NPCRIZ products are manufactured to GMP (Good Manufacturing Practice) standards. Purity, concentration, and microbiological cleanliness of each batch are verified in independent laboratories. Products carry EAC certification.

    What are peptide bioregulators
  
  Peptides are short protein chains of 2–50 amino acids. NPCRIZ's peptide bioregulators are particularly short: 2–4 amino acids. This size matters — it allows peptides to enter the cell and act at the DNA expression level without activating immune responses or allergic reactions.
  
    "Selectivity is the key property of these peptides: Libidon peptides act only on prostate cells, Vladonix on thymus cells, Sigumir on cartilage chondrocytes."
  
  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.

        eco
        Cytomaxes (natural)
      
      
        Origin: extracted from young animal (typically calf) tissues
        Composition: peptide complex (3–5 different di-/tri-/tetra-peptides)
        Example: Libidon — prostate peptides
        Range: 21 products, one per organ
        Suits: classic starting point, long-term therapy

        Cytogens (synthesized)
      
      
        Origin: chemically synthesized in a laboratory
        Composition: single short peptide (di- or tri-peptide) at high purity
        Example: Cartalax — cartilage dipeptide AED
        Range: 6 products, major systems
        Suits: vegan, impaired digestion, strict dose control
