Frequently Asked Questions

Research Use Only (RUO) indicates that products are designated exclusively for laboratory research, analytical testing, and educational purposes. RUO products are not intended for human or veterinary use, clinical diagnosis, therapeutic application, or any form of consumption. Purchasers acknowledge that products will be used solely within appropriate research settings by qualified individuals.

Northbridge Research Labs supplies peptides, amino acids, and related research compounds intended for in-vitro laboratory research and analytical applications. All materials are designated Research Use Only and are accompanied by relevant analytical documentation where applicable.

Our products are available to qualified researchers, academic institutions, laboratories, and organizations conducting legitimate research. Purchasers must acknowledge the Research Use Only designation and agree to our Terms of Service, which prohibit human or veterinary use of any products.

No. Northbridge Research Labs does not provide guidance on human or veterinary use, dosing, administration protocols, or expected outcomes. We supply research materials with analytical documentation only. Researchers are responsible for developing their own methodologies within their respective institutional guidelines.

A Certificate of Analysis (COA) is an analytical document that provides information regarding compound identity, purity assessment, and testing methodology. COAs are generated through independent third-party laboratory analysis and are provided for informational purposes to support research verification and documentation requirements.

Where applicable, compounds undergo analytical testing using methodologies such as High-Performance Liquid Chromatography (HPLC) for purity assessment and Mass Spectrometry (MS) for molecular weight confirmation and compound identification. Testing is performed by independent third-party laboratories.

Certificates of Analysis are public and downloadable, before or after you buy. Enter the lot number printed on your vial in our COA library to pull up the certificate for that exact batch, or open the certificate on any product page. If you need anything beyond the certificate, our team is happy to help.

Purity percentage, as reported on analytical documentation, indicates the proportion of the target compound relative to detected impurities based on the specific analytical method employed (typically HPLC). This information is provided for research reference and does not imply suitability for any specific application.

Each new production run carries a lot number printed on the vial. That number ties the vial to its independent certificate in our COA library, so researchers can reference the exact batch in their records for reproducibility. Earlier batches are being added to the library as they're re-certified.

Storage recommendations vary by compound. Generally, lyophilized (freeze-dried) peptides should be stored in a cool, dry environment, typically at -20°C or below for long-term storage. Reconstituted solutions may require refrigeration at 2-8°C and should be used within a timeframe appropriate for the specific compound. Always refer to product-specific documentation for storage guidance.

Lyophilization, or freeze-drying, is a preservation process that removes water from compounds while maintaining structural integrity. Lyophilized peptides are typically more stable during storage and shipping compared to solutions. Reconstitution with appropriate solvents is required before use in research applications.

Products are packaged according to handling standards suitable for research materials. Packaging is designed to maintain compound integrity during transit. Temperature-sensitive items may include appropriate packaging materials to preserve stability during shipping.

Common reconstitution solvents for research peptides include bacteriostatic water, sterile water, or other appropriate buffers depending on the compound's solubility characteristics. Researchers should determine appropriate solvents based on their specific research protocols and compound specifications.
