It exhibits selective action on thymus tissue \u2013 improving thymic metabolism and tissue regeneration to restore T-cell synthesis, maturation and release. Unlike Vladonix (natural thymus extract), Crystagen as a Cytogen acts faster but with shorter duration. Research demonstrates Crystagen activates B-cell immune pathways in the spleen, increases CD3+\/CD4+ T-cell counts, normalises CD4+\/CD8+ ratios, preserves thymic cortex-medulla architecture, stimulates thymocyte proliferation (PCNA expression), and exhibits immunogeroprotective effects in gamma-irradiation accelerated ageing models.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Crystagen (Pro-Glu-Asp \/ PED tripeptide, Khavinson Cytogen AC-5\/AC-6 immune bioregulator) 20mg \u2014 &gt;=99% HPLC purity, MS confirmed, Janoshik COA.
