Frequently asked questions

What information should I review for a peptide product?

Review the compound identity, formulation, stated quantity, intended use and batch documentation. Molecular identifiers describe the compound; analytical reports describe the tested sample. For blends, check the individual components and their stated amounts.

What is a certificate of analysis?

A certificate of analysis (COA) is a report of test results for a particular sample or batch. Where a document is supplied, compare its product name and batch or lot number with the item. A certificate does not by itself establish medical approval or suitability for human use.

What do HPLC and LC-MS results tell me?

High-performance liquid chromatography (HPLC) separates sample components and can be used to assess purity under a stated method. Liquid chromatography–mass spectrometry (LC-MS) can support identification. Neither result alone establishes sterility, safety or suitability for a particular use.

Where can I find product specifications?

Review the specifications and documents linked in the product details. To request further information, send the product name and any batch or lot reference to our team. Testing coverage should be established from the relevant report.

How do I enquire about a product?

Use the enquiry link in the product details to contact our team about availability, specifications and documents. The catalogue is enquiry-only; any sale is subject to confirmation of product eligibility and destination requirements.

Do you accept international enquiries?

Yes. GL Biochem Peptide is based in China and the UK and welcomes worldwide enquiries. Availability and shipping eligibility must be confirmed for each destination.

How should a product be stored or handled?

Follow the product-specific label, supplier instructions and safety data sheet where provided. Storage conditions depend on the formulation and packaging; do not assume that all peptides need the same temperature or handling. Request missing instructions before handling a product.

How can I check delivery options?

Include your destination country and product name in your enquiry. Our team can review the applicable arrangements; request confirmation of available shipping options, charges, delivery estimates and import requirements before proceeding.

Can you advise on medical use?

This website does not provide medical advice, dosing or administration instructions. Intended use and any applicable restrictions must be checked for each product. A research label or a purity result is not evidence of approval for human or veterinary use.
