Every production batch undergoes strict release testing using validated reverse-phase High-Performance Liquid Chromatography (RP-HPLC) against USP or EP primary reference standards. For NMN, we verify the stereospecific beta-anomer form to exclude biologically inactive alpha-isomers. For S-Adenosyl-L-Methionine (SAMe), we analyze the active (S,S)-diastereomer ratio via ion-pair chromatography, ensuring it meets pharmaceutical release limits (≥75% active form). Full chromatograms and method parameters are shared on the batch COA.

We operate in accordance with USP <232>/<233> for elemental impurities using Inductively Coupled Plasma Mass Spectrometry (ICP-MS), ensuring Lead (≤0.5 ppm), Arsenic (≤0.5 ppm), Cadmium (≤0.2 ppm), and Mercury (≤0.1 ppm) conform to strict California Proposition 65 thresholds. Residual solvents are monitored by Headspace Gas Chromatography (GC-HS) under USP <467> guidelines. Pesticide profiles are screened against 400+ agricultural residues via tandem LC-MS/MS, confirming absolute zero organochlorine or ethylene oxide contamination.

Yes. We provide custom milling and micronization from standard 80 mesh down to ultrafine 200–300 mesh for liquid/suspension solubility, or wet-granulated DC grades (Direct Compression) with high bulk density (0.55–0.75 g/mL) and low angle of repose (<30°) for high-speed tableting. We also support custom moisture targets to prevent hydrolysis in hygroscopic formulations containing botanical extracts and amino acids.

Sensitive compounds like SAMe, Serrapeptase, and Melatonin are packaged in food-grade multi-layer aluminum foil bags, purged with pharmaceutical nitrogen, and vacuum-sealed with food-grade molecular sieve desiccants. External drums are reinforced HDPE fiber drums (25 kg standard). For thermolabile shipments requiring temperature control during international transport, we coordinate refrigerated reefer containers or insulated air pallets packed with calibrated phase-change material (PCM) data-loggers.

We welcome both on-site and remote video audits of our 60,000 m² Xi'an manufacturing plant. Furthermore, we regularly cross-validate lot results through accredited third-party laboratories including SGS, Eurofins, and NSF International. Third-party testing reports for identity, potency, and microbiological purity can be commissioned directly per client purchase order specifications.

Standard stocked catalog items (such as D-Mannose, NMN, DIM, and Coenzyme Q10) carry an MOQ of 1 kg for pilot formulations and 25 kg for standard production runs, with dispatch within 3–5 business days. Custom engineered runs, specialized particle sizes, or proprietary extractions require 100 kg to 500 kg minimums with a 2-to-3 week lead time. Commercial quotes are provided on FOB, CIF, or DDP terms via wire transfer (T/T) or Letter of Credit (L/C).
