What is Crystagen??

Crystagen (peptide complex AC-5/AC-6, amino acids Pro-Glu-Asp) is a synthetic short-peptide bioregulator from the Khavinson Cytogen family, developed at the St. Petersburg Institute of Bioregulation and Gerontology for immune system restoration. It exhibits selective action on thymus tissue – 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.

Research Applications

Thymic Tissue Regeneration

Thymic metabolism restoration, cortex-medulla architecture preservation, T-cell maturation and release enhancement

T-Cell Immunology

CD3+/CD4+ T-cell count normalisation, CD4+/CD8+ ratio restoration, T-helper cell activation, PCNA proliferation marker

B-Cell & Splenic Immunity

B-lymphocyte activation in spleen, immunomodulatory effects distinct from T-cell bioregulators (vilon, thymogen)

Immunogeroprotection

Gamma-irradiation accelerated ageing model – thymic preservation, macrophage/mast cell restoration, age-related immune decline reversal

Immunodeficiency Restoration

Secondary immunodeficiency models (radiation, chemotherapy, infection) – immunogram normalisation, asthenic syndrome reduction

Frequently Asked Questions

How do I reconstitute this peptide?
Add 1–2mL bacteriostatic water to the lyophilized vial by directing water down the inner wall of the vial. Swirl gently until the powder fully dissolves — do not shake or vortex. The solution should be clear and colourless. Use immediately or refrigerate at 2–8°C.
How should this peptide be stored?
Store lyophilized peptide vials at −20°C for long-term storage. Once reconstituted, store at 2–8°C (refrigerator) and use within 21–28 days. Avoid repeated freeze-thaw cycles, direct light, and heat exposure.
What purity is this Vesta compound and how is it verified?
All Vesta compounds are tested to ≥99% purity by HPLC peak area analysis on every production batch. Molecular identity is confirmed by mass spectrometry. A Certificate of Analysis (COA) is published on the product page and independently verifiable at verify.janoshik.com using the batch reference number.
