Normalizes thymus-derived peptide signaling pathways

Summary

Crystagen is a thymic-derived peptide bioregulator that modulates immune function, supports thymic repair, and enhances lymphocyte output. It is administered orally and has been shown in Eastern European research to improve immune performance in aging and immunosuppressed individuals.

How it works

  • Normalizes thymus-derived peptide signaling pathways
  • Stimulates lymphocyte differentiation and cytokine balance
  • Restores immune regulatory gene expression in aged individuals

Dosing

  • unit: capsules
    low dose: 1
    frequency: Daily
    high dose: 3
    standard dose: 2
    administration route: Oral

Cycling

  • Typical course: 10–30 days of daily dosing. Repeat up to 2–3x per year for immune maintenance.
