How Crystagen Works

Crystagen is a synthetic tripeptide bioregulator derived from thymic peptide sequences that acts on the immune system. It penetrates cells via proton-dependent oligopeptide transporters (PEPT1/PEPT2) and interacts with DNA to modulate transcription of genes related to immune cell differentiation, heat-shock responses, and cell-cycle control. It promotes T-lymphocyte differentiation and proliferation, normalizes CD4+/CD8+ ratios, stimulates thymic epithelial cell activity, and modulates cytokine secretion (IL-1, TNF-alpha) from macrophages.

Frequently Asked Questions

Crystagen (CAS: 857267-11-9) is a research compound, with a molecular weight of 359.34 Da in the Specialty / Research category. Crystagen is a synthetic tripeptide bioregulator derived from thymic peptide sequences that acts on the immune system. It penetrates cells via proton-dependent oligopeptide transporters (PEPT1/PEPT2) and interacts with DNA to modulate transcription of genes related to immune cell differentiation, heat-shock responses, and cell-cycle control. Researchers commonly investigate Crystagen for Immune system regulation and restoration, T-cell differentiation and maturation, Thymic function in aging. Every vial from MiPeptidos includes batch-specific analytical documentation.
To reconstitute your Crystagen 20mg vial, let it reach room temperature for about 15-20 minutes out of the freezer. Slowly inject 3-5mL of bacteriostatic water along the inside wall of the vial — never aim directly at the peptide cake. Gently swirl until the powder fully dissolves; never shake, as this can denature the peptide. Store reconstituted Crystagen at 2-8°C and use within 30 days. MiPeptidos includes bacteriostatic water for purchase alongside all peptides.
Crystagen (Glu-Asp-Pro, 359 Da) is one of the smallest immune-modulating peptides available — a Khavinson tripeptide bioregulator that targets immune cell gene expression and thymic function. Thymosin Alpha-1 (3108 Da) is a much larger 28-amino acid thymic peptide that activates TLR9 and dendritic cells. Crystagen ultra-small size (just 3 amino acids) allows direct nuclear penetration for gene-level regulation, a different approach than receptor-mediated Thymosin signaling. MiPeptidos carries both.
Store lyophilized Crystagen at -20°C for maximum long-term stability — properly stored, it remains potent for 24+ months. Once reconstituted with bacteriostatic water, keep it refrigerated at 2-8°C and use within 30 days. In research applications, Crystagen has a reported half-life of Short; rapidly absorbed due to ultrashort peptide size (~359 Da), which informs dosing frequency and protocol design. Avoid repeated freeze-thaw cycles and protect from direct light. MiPeptidos ships every order with cold-chain packaging to maintain integrity during transit.
Every Crystagen order from MiPeptidos includes a batch-specific Certificate of Analysis. Our current batch (HR-CRYS-2600115, tested January 27, 2026) shows 99.3% purity by HPLC, mass spectrometry confirmation at 359.34 Da, endotoxin levels below 0.1 EU/mg, and passing sterility per USP <71>. This level of documentation ensures you can verify compound identity and purity before beginning your research. MiPeptidos also offers bulk pricing on orders of 50+ vials — contact info@mipeptidos.com.
