Independently third-party tested

Certificate of Analysis

Every peptide we sell is third-party tested, with full documentation of purity and identity verification. Certificates are being onboarded and post per batch as lab results return.

Transparency you can trust

A Certificate of Analysis is your proof that what’s on the label is what’s in the vial. We believe in complete transparency, on every order.

Our testing methods

HPLC purity analysis

High-performance liquid chromatography separates and quantifies peptide components to verify the 99%+ purity standard.

Mass spectrometry

Precise molecular-weight measurement confirms peptide identity and structural integrity against the specified sequence.

Identity verification

Sequence confirmation ensures the compound in the vial matches the labeled research reference — no substitutes.

Batch documentation

Each batch is accompanied by documented quality controls tracking identity, content, and appearance prior to release.

Product certificates

Search by product to find its Certificate of Analysis. Certificates are being onboarded — every product is listed below with its current status.

How to access your COA

Three steps to pull up the full report for the exact lot in your hands, once its certificate is posted.

1

Find your product

Locate the batch number printed on your vial label, or open the product page for your peptide.

2

Match the batch

Search that batch number in the certificate finder above to pull up its exact report once results are posted.

3

Verify results

Review the purity percentage, identity confirmation, and test date for your specific lot as each certificate goes live.

COA questions

We're standing up independent third-party testing now, and certificates aren't posted yet — lab results are still pending. Every product is listed on this page with a “COA pending” status so you can see exactly what's coming. As each batch's results come back, its certificate will appear here under the matching product.

A COA is a document from an independent laboratory verifying the identity and purity of a specific batch — confirming that what's on the label matches what's in the vial. It reports purity by HPLC and identity by mass spectrometry, tied to the batch number.

Each batch number printed on your vial will correspond to a certificate on this page. You'll search that number in the bar above — or follow the COA link on the product page — to pull up the report for your exact lot.

Our standard is independent third-party analysis: HPLC for purity (we hold a 99%+ standard) and mass spectrometry for identity confirmation. We don't self-certify our own purity or identity results.

Yes. All testing is performed by accredited independent laboratories — never in-house. This keeps verification objective: we never grade our own work.
