Transparency summary

What the current records support, and where evidence is incomplete.

What we could verify

9 research peptide products tracked across 8 peptides.
5 product records have a verified independent laboratory report.
The supplier explains how batches are tested and traced.

What we could not verify

No registered company, company number or postal address was found on the supplier’s site.

Not confirmed does not mean it does not exist. A supplier’s own statements are distinct from independently verified testing.
