Synthetic Peptide Versus Natural Peptide Complex Language

  • Crystagen is often discussed with both “synthetic peptide” and “natural peptide complex” language. Patent literature describes production by classical peptide synthesis, which supports synthetic peptide terminology for the claimed sequence [1].
  • The broader peptide-bioregulator field also includes natural tissue-derived preparations and synthetic analogs. A PubMed-indexed review of natural and synthetic thymic peptides discussed differences between thymus-derived preparations such as Thymalin and synthetic thymic peptides such as Thymogen 9. For Crystagen, the safest editorial approach is to specify which source describes which form.
