Production Process and Purification
The manufacturing of NAD peptide follows a multi-step solid-phase peptide synthesis (SPPS) protocol, utilizing Fmoc chemistry to ensure precise amino acid sequence assembly. After synthesis, the crude peptide undergoes reverse-phase high-performance liquid chromatography (RP-HPLC) purification, achieving the target purity threshold. Lyophilization is performed under sterile conditions to produce a free-flowing powder with consistent particle size distribution.
Third-Party Testing and Certification
Each batch of NAD peptide is subjected to rigorous quality control measures, including mass spectrometry (MS) for molecular weight confirmation, HPLC for purity analysis, and amino acid analysis for sequence verification. Third-party testing by ISO 17025 accredited laboratories provides independent validation of these parameters. Certifications commonly associated with premium NAD peptide include:
- Certificate of Analysis (CoA) with detailed purity and impurity profiles.
- Heavy metal testing report confirming compliance with USP/EP standards.
- Microbiological testing for total aerobic microbial count and yeast/mold.
- Residual solvent analysis per ICH Q3C guidelines.
- Stability study data under accelerated and long-term storage conditions.
