CERTIFICATES OF ANALYSIS
(COA)
A Certificate of Analysis (COA) is an official laboratory document that verifies the purity, identity and composition of a specific batch of material. For peptides, a COA confirms that the sample meets the supplier’s stated specifications (such as ≥ 99 % purity) and is free of contaminants. Each certificate lists the lot number, the tests performed (for example HPLC purity and sterility assays) and the actual results, and it bears the signature of an authorized analyst. Researchers rely on COAs to ensure their reagents are accurately characterized and reproducible; using peptides without a COA can lead to flawed experiments and compliance issues. Having a COA on file demonstrates that the supplier has tested the product and provides confidence that the material used in the study meets defined quality standards.
What You Can Expect:
All Lyphtide batches undergo comprehensive UPLC/MS testing by a U.S. cGMP laboratory to check purity, confirm correct strength, and detect any impurities. This level of quality control provides researchers with materials they can trust for accurate and repeatable data. Each COA provides detailed testing results to ensure quality, purity, and transparency for research purposes. We strive to provide a batch-specific Certificate of Analysis (COA) for every product we carry. These documents typically include:
Purity results using trusted methods like HPLC, Mass Spec, or NMR
Molecular identification and composition data
Batch numbers and manufacturing dates for traceability
Manufacturer-issued COAs confirming quality and composition
When available, independent third-party testing for added assurance
Note: While most of our products include a COA, a small number of batches may have COAs pending or temporarily unavailable. If a COA is not currently listed, we are happy to provide an update or expected availability upon request.
Trusted Sources. Vetted for Quality.
We don’t work with just anyone. At Lyphtide, we’ve meticulously vetted and partnered with a select group of highly reputable manufacturers.
Our sourcing decisions are based on:
Proven consistency in testing and documentation
High production standards and facility compliance
Transparent communication and ethical practices
We do not source from generic bulk resellers. Our goal is to support your research with compounds that are pure, reliable, and thoroughly reviewed.
Why It Matters:
In an industry where trust can be hard to come by, Lyphtide is committed to full transparency. Through strict supplier selection and consistent documentation, we aim to give researchers the peace of mind they deserve when sourcing materials.
