A supplier saying its products are tested is not the same as a published laboratory report for the exact vial. Each product page shows what evidence was actually found.

Transparency summary

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

What we could verify

Trading company: FESOBELLA LTD (company number 17439704).
The company number resolves to an active company on Companies House.
Registered office: 71-75 Shelton Street, Covent Garden, London, WC2H 9JQ.
16 research peptide products tracked across 9 peptides.
4 product records have a verified independent laboratory report.
The supplier explains how batches are tested and traced.

What we could not verify

Evidence applies to the stated products and batches, not everything the supplier sells.

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