FAQ - :

Q: What is the difference between Feed Grade, Food Grade, and Pharmaceutical Grade L-Lysine?

A: Pharmaceutical Grade (like ours) has the highest purity standards, strictest limits on impurities (heavy metals, residual solvents, microbes), and adheres to pharmacopeia monographs (USP/EP/JP). It's produced under GMP and undergoes rigorous QC testing for use in drugs and high-end supplements. Food Grade has lower purity requirements, Feed Grade lower still.

Q: Can I get L-Lysine HCl suitable for injection applications?

A: Yes, we supply low-endotoxin L-Lysine HCl specifically controlled for parenteral use. Please specify your requirement when inquiring.

Q: Do you offer custom specifications or packaging?

A: Yes, we can discuss tailored solutions based on your specific project needs. Contact our sales team.

Q: What documentation do you provide with each shipment?

A: We provide a detailed Certificate of Analysis (COA) for each batch and a Material Safety Data Sheet (MSDS). Additional regulatory documents are available upon request.

Q: What is your minimum order quantity (MOQ)?

A: Our standard MOQ is [25] kg. We offer you flexible MOQ, please contact us. Please contact us for specific quantities and pricing.
