Crystagen
Tetrapeptide bioregulator (EDPG)
An immune-oriented peptide bioregulator studied for normalizing lymphocyte populations in aged models.
How it works
Described as regulating gene expression in immune tissue, restoring balance across T and B lymphocyte subsets rather than broadly stimulating them.
What research has shown
Russian studies report normalized immune indices in aged and immunosuppressed cohorts; independent data is scarce.
