Investigate Peptides Support testing

Independent peptide investigation

Follow the sample.
Read the result.

We source research peptides independently, document their path to the lab, and publish third-party findings on identity, purity, and net content in mg. Every outcome is public.

Public record

Test results

Measured net content against the label claim, purity, and identity for each vial — with the original lab report one click away.

Sample-specific evidence

Tested suppliers

Every supplier we have published results for, built directly from the records above. Choose one to filter the results to its samples.

Listings are evidence records, not endorsements or certifications.

Our process

A traceable path from vial to report.

A supplier’s own COA can’t tell you what a separately bought vial contains. So we buy our own, send them to a lab, and show you what came back.

  1. 01

    Source

    Purchase or receive the vial. Record supplier, retailer, peptide, lot, date, and any product or funding relationship.

  2. 02

    Document

    Capture packaging and vial labels, assign a sample ID, and retain the original handling record.

  3. 03

    Submit

    Record packing, shipment, receiving lab, requested tests, and the IDs connecting the vial to the report.

  4. 04

    Publish

    Post identity, purity, measured net content, and source documents regardless of outcome.

  5. 05

    Cross-check

    When the same lot is tested at multiple facilities, display the reports together and explain differences.

Independent sourcing

We disclose whether a vial was purchased or received and identify the source for each result.

Documented handling

Each record can include packaging, labeling, shipment, and laboratory documents.

Every outcome

Failures and inconclusive findings stay public. Same-lot tests at multiple labs are linked.
