Who We Are

CertiPeptide is the international research brand of Guangzhou Weihua Biotechnology Co., Ltd. — a supplier of laboratory research products. This website provides product specifications, published batch documentation and support for purchasing enquiries.

Product specifications describe the listed SKU and packaging. Published COAs provide results for the named sample and batch; they are not a guarantee of every material property or a substitute for your laboratory’s assessment.

Our company page lists our operator and registered address. A registered address does not identify an order’s dispatch warehouse; shipping details are confirmed for the order.

Why Researchers Choose Us

Product information and documentation to support purchasing decisions.

Research Supply

Browse product specifications, pack sizes and published batch documentation before ordering. Contact our team for product availability and bulk supply requirements.

Quality Assurance

Published COAs identify the tested product, SKU, batch and reported methods. Review each result and the original document; testing coverage differs between reports.

Documented Results

Read measured purity, fill, identity and other results when reported. A purity measurement alone does not establish additive content, sterility or suitability for any intended use.

Wholesale First

Contact our team for wholesale quotations, volume requirements and available documentation. Product availability and order-specific terms are confirmed in your quotation.

Quality & Testing

Test results belong to a specific sample and report. Our report pages show the recorded values, units, methods and dates. Read the original document to understand what was tested.

Use the product, SKU and batch number to find the matching report. Public historical reports do not establish which batch will be allocated to a future order. Verification links may require an account with the report provider.
