Which GCC research suppliers publish batch-level certificates?

The question

Most research-peptide storefronts say their products are tested. Fewer let you see the certificate for a specific batch before you buy, and fewer still let you confirm that certificate with the laboratory that issued it. This comparison sets out how five UAE-based suppliers handle certificates, using the same criteria for each.

Four models we found

1. A public batch library with verification at the laboratory. Every row links to a record or report on the testing laboratory’s own site (SHLabz; BodyPharm for two compounds, with in-house HPLC results hosted on its own site for the rest).
2. Lot documentation and verification on the supplier’s own site, with named external laboratories (VaultLabs).
3. Lot-matched certificates on request, with a named laboratory and a stated practice of sending the certificate with each order (Dubai Peptides).
4. A testing claim, with the library and laboratory names not recorded in our capture (Afiya Labs). Our capture was text-only, because the site blocks direct connections from our network.

Why the model matters

Each model can be operated honestly. The difference is how much you can check yourself, and when. A public library verified at the laboratory lets you check before ordering. A certificate on request or with the order lets you check after. Our guide on verifying testing claims explains the evidence levels.

Scope differs too

Publishing certificates is one question. What they cover is another. One library in this comparison reports heavy-metal, endotoxin and sterility results for each batch. Another reports purity and measured content only. Compare the tests that matter for your work, not the number of certificates.

A note on fairness

“Not recorded in our capture” means we did not find the item on the pages we checked on 14 October 2026. It does not mean the supplier does not do it. Suppliers can send us documents through the corrections page, and we will re-check and update the table.
