A reference for PeptaLux compound sourcing, third-party testing, batch documentation, and cold-chain logistics.
This page documents how PeptaLux sources, tests, and ships research compounds, and where to find the verification data for any specific batch.
PeptaLux compounds are produced and tested to a ≥99% purity benchmark by high-performance liquid chromatography (HPLC). Identity and purity are confirmed on a batch-by-batch basis by independent, accredited third-party laboratories. The specific purity figure, methodology, and test date for any individual batch are stated on that batch’s Certificate of Analysis (COA), which is the authoritative record for that batch and governs over any general figure stated elsewhere on this site.
A Certificate of Analysis issued for a batch may include:
Available COAs are published in our COA Library. COAs reflect the testing of representative samples from a given batch and are provided for laboratory reference only. PeptaLux does not warrant that any individual unit conforms to any specific COA beyond the scope of the representative sample tested for that batch, and the COA does not constitute a guarantee of fitness for any particular purpose.
We work with established peptide-synthesis facilities operating under documented quality systems. Each product carries a batch identifier that traces back through fulfillment to its corresponding COA, allowing customers to verify provenance for a specific shipment.
Compounds are stored under temperature-controlled conditions at our fulfillment facility and ship in insulated packaging with gel packs designed to maintain a cold-chain environment in transit. Each shipment includes a temperature indicator so the customer can assess cold-chain integrity on receipt. PeptaLux ships exclusively from within the United States to U.S. addresses only.
If a shipment arrives in a condition suggesting a temperature excursion, the customer should contact support@peptalux.com within seventy-two (72) hours of delivery. Eligibility for any remedy is governed by our Refund Policy.
PeptaLux supplies research compounds for in vitro laboratory use only. We do not publish dosing guidance, reconstitution protocols, application notes, or research methodology. Those determinations are the sole responsibility of the qualified researcher, applied under the qualified-researcher attestation that every order requires. Our role begins and ends with delivering a documented, verified compound to a qualified laboratory.
Specifications for individual compounds — molecular formula, mass, sequence (where applicable), and recommended storage — are listed on each product page. Verification data is available in the COA Library. All products require acceptance of our research-use attestation at checkout, consistent with our Research Use Notice and Terms and Conditions.
