How we document what we ship
Every item in the PureTy Peptides catalog is intended solely for laboratory research. For research use only. Not for human or animal use. We publish the same specification fields on every product listing so that a buyer can compare items without guessing: modality, presentation, and purity target.
Purity target
Catalog listings state a purity target of 99% or greater. Purity is assessed by the manufacturing source, and the figure shown on a listing is the specification for that item rather than a measured result for an individual vial.
Certificates of Analysis
A Certificate of Analysis (COA) is the document that reports analytical results for a specific production lot. Where a COA is available for a catalog item, a Download COA button appears directly on that product page. If no button is shown, a lot-specific COA has not yet been published for that item.
To request a COA for a lot you have already received, or to ask whether documentation is available before ordering, contact us with the product name and, if you have it, the lot number.
Handling and storage
Research peptides are sensitive to temperature, light, and moisture. General laboratory practice is to keep lyophilized material cold and dry until reconstitution, to protect it from light, and to avoid repeated freeze-thaw cycles once reconstituted. Storage requirements vary by compound. Confirm the appropriate conditions for your specific application before use.
Who we sell to
Products are supplied to qualified laboratory and research buyers only. By placing an order you confirm that the materials will be handled by appropriately trained personnel in a controlled research setting, and that they will not be administered to humans or animals.
What we do not provide
We do not provide dosing guidance, administration protocols, therapeutic advice, or any suggestion that a catalog item is suitable for diagnostic or clinical use. Nothing in this catalog has been evaluated by the U.S. Food and Drug Administration, and no item is approved as a drug, supplement, or medical device.
For research use only. Not for human or animal use.
