FAQ

Every batch synthesized undergoes rigorous High-Performance Liquid Chromatography (HPLC) and Mass Spectrometry (MS) testing in cGMP-certified cleanrooms. We verify molecular weight, amino acid sequence integrity, and confirm total impurities remain below 1.0%. Downloadable batch-specific COAs are accessible for every product.

Lyophilized (freeze-dried) powder should be stored sealed in the original desiccated glass vials at -20°C for optimal long-term stability (up to 24 months). For short-term storage up to 3 months, 2°C to 8°C refrigeration is acceptable. Always protect compounds from UV light and thermal fluctuations.

No. In strict adherence to UK biochemical supply regulations, all materials provided by AX Peptides are sold strictly for in-vitro laboratory research and analytical development. They are not approved for medical, diagnostic, clinical, therapeutic, veterinary, or personal human consumption.

Reconstitution should be conducted within a sterile laminar flow hood using laboratory-grade bacteriostatic water or sterile saline. Gently inject the solvent down the inside wall of the vial without agitating or shaking the peptide cake, allowing spontaneous dissolution to preserve tertiary molecular structure.
