ZENTRA supplies lyophilised research peptides for laboratory, analytical and scientific use. This catalogue brings together individual compounds, peptide analogues and selected research blends, with product information written to help laboratories compare format, molecular data and available batch evidence.
Testing results can vary between products and batches, so purity and identity claims should always be checked against the certificate linked to the specific batch. Our batch verification centre provides the available third-party reports rather than relying on one blanket purity figure across the entire range.
Available batches are supported by third-party analytical documentation. Batches undergo HPLC purity analysis and mass-spectrometry identity confirmation.
Use the product batch number or QR code to find the matching report. The result shown on one certificate should not automatically be assumed for a different product or batch.
Research compounds are dispatched from the UK in protective packaging. Product pages state the supplied format and provide compound-specific storage and handling information.
Start with the evidence attached to the exact product and batch. HPLC is commonly used to estimate chromatographic purity, while mass spectrometry supports molecular identity. These methods answer different questions, so a strong analytical record should state what was tested, when it was tested and which batch the result belongs to.
For a straightforward introduction to peptide structure, terminology and laboratory context, read What Are Peptides?. Product pages then provide the relevant molecular information, supplied quantity, physical form and current COA links.
No. Products in this category are supplied exclusively for laboratory, analytical and scientific research and are not intended for human or veterinary use.
No. Analytical results relate to the product and batch identified on that report. Check the current batch-specific certificate rather than assuming that one result applies across the whole catalogue.
HPLC separates components in a sample and is commonly used to estimate chromatographic purity. Mass spectrometry measures mass-to-charge data and is used to support molecular identity. One test does not replace the other.
Most peptides are supplied as lyophilised material unless the individual product page states otherwise. Always use the product page and matching batch documentation as the source of truth.
Visit the Third-Party Tested COA and Batch Verification page and match the listed product and batch number to the item being reviewed.
