Identity
Confirm the stated molecule and supplied form. Start with the matching batch COA; request sequence-level evidence only when the buyer's written procedure requires it and availability or a separate scope has been agreed.
Quality system
Specify the evidence before you specify the claim.
A research peptide can meet a purity target and still fail an identity or content question. LyoPep structures qualification around the supplied form, the intended research workflow and a released batch.
Qualification matrix
Identity, purity and content are separate release questions.
Purity
Review RP-HPLC method conditions, wavelength, integration and related-peak handling. A percentage without the method is not enough.
Content
Net peptide content is not the same as gross lyophilized powder weight. Ask which assay supports the stated amount and whether water/counter-ion is addressed.
Stability
Follow the storage condition stated on the batch COA or label from receipt onward.
Batch COA library
Every published batch COA, by product
Every lot has its own COA. Review recent batch records for frequently requested products, then ask sales for the COA of the lot in your quote.

Batch release workflow
One controlled handoff from requirement to dispatch.
Released-batch COA
Each product inquiry can request the latest available COA for the lot being offered.
Pre-agreed independent testing
A mutually accepted specialist laboratory may be commissioned under an agreed method, fee allocation and acceptance rule. Unless otherwise agreed in writing, the buyer pays the cost of this optional testing.
Documented remedy
If your own independent test shows a product does not meet the specification on its COA, we refund that product in full; any other confirmed nonconformance is handled under the signed order terms, which may include replacement, credit or refund.
Buyer FAQ
Terms to settle before the purchase order
Can a buyer arrange third-party testing?+
Yes. You can send any vial from your order to an independent laboratory of your choice. If you want the laboratory, specification, sampling, method and acceptance rule agreed with us before testing, sales confirms them in writing. Unless otherwise agreed in writing, the buyer pays the cost of this optional testing.
What if my own lab test shows the product is out of specification?+
Send any vial from your order to an independent laboratory of your choice. If the report shows the product does not meet the specification on its COA — purity below the stated minimum, or an identity that does not match — share the report with our sales team and we refund that product in full.
Does HPLC purity prove peptide content?+
No. Chromatographic purity describes the relative peak profile under a stated method. Identity, water, counter-ion, residual solvents and assay/content may require separate methods.
How should material be stored after delivery?+
Move it into the storage condition stated on the batch COA or label as soon as it arrives, and record the package condition on receipt.
How are payment terms handled?+
Available methods and milestones depend on order value, destination and project type. The pro forma invoice should state currency, bank details, fees, payment milestones and the release condition.
Why must the testing laboratory understand peptide chemistry?+
Free-base and salt forms, hydrophilic and hydrophobic sequences, aggregation and adsorption can change sample preparation and method suitability. Use a laboratory experienced with the molecule class.
Materials still needed before production launch
Current pages avoid unverified certification and capacity claims. Provide valid certificates, anonymized released-batch COA examples, method SOP summaries, stability data, facility legal identity and third-party lab agreements before those claims are promoted.
