Third-Party Lab Testing

Vitrex is committed to complete transparency. Every compound we dispense is independently tested by accredited third-party laboratories before it ever reaches a patient. We do not self-certify — we verify.

What We Test For

• Purity (HPLC Analysis): High-Performance Liquid Chromatography confirms minimum 99.8% purity and identifies any impurities or degradation products.
• Identity (Mass Spectrometry): Mass spec analysis confirms the exact molecular structure and weight of each compound, verifying it is what we say it is.
• Sterility: All injectable preparations are tested for endotoxins (LAL test) and bioburden to ensure they are free from microbial contamination.
• Potency: Dose concentration is validated to within plus or minus 2% of the labeled amount.
• Heavy Metals: ICP-MS testing screens for lead, arsenic, mercury, cadmium, and other toxic metals.
• Residual Solvents: GC headspace analysis confirms no harmful synthesis solvents remain in the final product.

Certificate of Analysis (CoA)

Every order ships with a Certificate of Analysis — a full report of the lab results specific to your batch. Your CoA includes batch number, laboratory name and accreditation, test results for purity, identity, potency, and sterility, and pass/fail determination for each parameter.

Manufacturing Standards

All Vitrex products are manufactured in FDA-registered, cGMP-compliant facilities in the United States. This ensures consistent quality, safety, and reproducibility at pharmaceutical grade.
