Products
What types of products do you sell?
We offer a selection of peptide compounds and related research materials intended for legitimate laboratory research and scientific investigation.
Specifications, quantities, formulations, product availability, and other characteristics are identified on the applicable product page.
Where can I learn more about a particular Product?
The applicable Product page has product-specific information, including available specifications, format, quantity, and related research documentation. SDS sheets and COA should be available for each product.
What formats are available?
Available formats may vary by Product and may include different research presentations, quantities, or formulations. The applicable Product page identifies the specific format and quantity being offered.
Regardless of format, all Products remain subject to their Research Use Only restrictions.
What does “lyophilized” mean?
“Lyophilized” means that a material has undergone a freeze-drying process to remove water and produce a dry preparation. Lyophilization can support peptide stability and help minimize degradation when stored under appropriate conditions.
The exact characteristics, labeled quantity, storage requirements, and other specifications of a lyophilized product should be determined from the applicable product page, product label, and product documentation.
Are laboratory supplies included with a Product?
No. Accessories, diluents, solvents, laboratory supplies, or other materials should not be assumed to be included merely because they may be useful for a particular research application.
How do I confirm the quantity or format I am ordering?
Before completing checkout, review the Product name, selected variant, labeled quantity, Product description, and cart details.
If any specification is unclear, contact us before placing the order and identify the specific Product or Product page in question.
Quality & Testing
What is a Certificate of Analysis (CoA)?
A Certificate of Analysis (CoA) is a quality-control document associated with a product or product batch. Depending on the Product and testing performed, a CoA may identify the product and batch and report analytical results such as identity, purity, assay, molecular characteristics, or other applicable quality attributes.
For information about the reported analytical characteristics of a particular batch, refer to the applicable batch-specific documentation rather than general statements presented on a product page.
Are your CoAs batch-specific?
Yes. Each Certificate of Analysis (CoA) is specific to the applicable product batch or lot and reports the analytical information associated with that batch. Customers should retain the applicable CoA with their research records and verify that the batch or lot information on the CoA corresponds to the product received.
How do I find the correct CoA for my Product?
The applicable Certificate of Analysis (CoA) can be found through the CoA Library, via the CoA link on the applicable product page, or by scanning the QR code provided on the product packaging or label, where applicable.
Before relying on a CoA, verify that the product, batch, or lot information on the CoA corresponds to the product received. If you cannot locate the applicable CoA or believe the documentation does not correspond to the product received, contact support for assistance.
Are your Products third-party tested?
Yes. Our Products are tested by independent, third-party laboratories. The applicable Certificate of Analysis (CoA) identifies the testing performed and reports the applicable analytical results for the corresponding product batch or lot.
Testing may vary by product, batch, analytical method, and applicable testing requirements. Customers should refer to the applicable CoA and product documentation for batch-specific testing information.
What testing is performed?
Testing may vary by product. The specific tests performed for a particular product or batch are identified in the applicable analytical documentation where available.
What does a purity percentage actually measure?
A reported purity percentage is an analytical measurement obtained using a specified testing method and set of analytical conditions. It should be interpreted in the context of the applicable analytical method and CoA and does not, by itself, establish that a product is free of impurities or establish safety, efficacy, or suitability for a particular research application.
Can two batches have different analytical results?
Yes. Analytical results may vary between batches because of normal manufacturing, sampling, analytical variability, and other factors.
The batch-specific CoA provides the applicable analytical result reported for that particular batch.
Does a CoA guarantee research results?
No. A CoA documents specified analytical characteristics of a product or batch. It does not guarantee experimental performance, biological activity, reproducibility, or any particular research outcome.
What if the batch number on my Product does not match the CoA?
The batch number on the Product should correspond to the applicable CoA. If you notice a discrepancy, please contact us promptly with the product name, batch or lot number, and order information so we can review it.
Documentation & Research Records
Why is batch traceability important?
Batch traceability allows research materials to be associated with a specific product batch or lot and its corresponding documentation. Maintaining this information can support inventory management, research records, reproducibility, and identification of the materials used in particular experiments.
What Product information should I retain?
Where applicable, researchers may wish to retain the Product name, batch or lot number, quantity, CoA, date received, storage information, and other documentation relevant to their laboratory records, institutional requirements, or research activities.
Should I keep my CoA?
Yes. We recommend retaining the CoA and other applicable product documentation with your laboratory and research records. Keeping these records helps maintain documentation of the specific product batch or lot associated with your research materials.
What should I do if Product documentation appears inconsistent?
If Product documentation appears inconsistent with the Product or its batch or lot information, do not assume that the documentation applies to that material. Contact support with the Product name, batch or lot number, order information, and relevant documentation so that the discrepancy can be reviewed.
Storage & Handling
How should Products be stored?
Follow the storage requirements stated on the applicable Product label, Product page, and Product documentation. Storage requirements may vary between products, so use the instructions provided for the specific product.
Why do storage requirements vary by product?
Different materials can have different stability characteristics, and factors such as formulation, packaging, and physical state may affect appropriate storage conditions. For this reason, storage requirements are specified for each product.
What should I do if the package appears damaged?
If the package appears damaged upon arrival, photograph the package and shipping materials before opening it. If the product or packaging inside also appears damaged, photograph the product, seal, label, and packaging. Do not use or discard the product or packaging while the matter is being reviewed. Contact support promptly with your order and batch information so the issue can be reviewed.
