What we found
Sterling Prime Peptides checked 21 September 2026: sterlingprimepeptides.co.uk is a live Shopify storefront trading as "Sterling Prime Peptides" (GBP checkout currency). Its name closely resembles the already-tracked sterlingpeptides.co.uk, which went dead (DNS non-resolution) in early September 2026, but no shared contact email, company registration or other evidence linking the two was found on this pass, so they are recorded as separate, unconfirmed whether related. No testing-lab name, certificate or verify link found; no company registration or address published. What would move this listing: a verifiable Janoshik (or other named-lab) report printing Sterling Prime Peptides as the client.

Questions people ask about Sterling Prime Peptides
Is Sterling Prime Peptides legit?
Sterling Prime Peptides (sterlingprimepeptides.co.uk) is on The Peptide Watch's watch list. It does not publish a certificate of analysis that can be independently verified in its own name, so its quality claims rest on trust rather than checkable evidence. That is not proof of a scam; it means the evidence does not check out.
Does Sterling Prime Peptides publish a real, verifiable Certificate of Analysis?
Not one that can be independently verified in its own name. ⚠ No testing claim found. Sterling Prime Peptides (sterlingprimepeptides.co.uk) sells 5-Amino-1MQ, Adamax, AHK-Cu, AOD-9604, ARA-290 and other research peptides in GBP. The site names no independent testing lab and publishes no certificate of analysis or verify link.
How do I check Sterling Prime Peptides's certificate myself?
Find the certificate on sterlingprimepeptides.co.uk and read four things: an independent laboratory is named; the client field names Sterling Prime Peptides, not a supplier; the compound line names the peptide you are buying, not only a batch code; and the report opens on the laboratory's own website from its task number and key (verify.janoshik.com for Janoshik). Then compare the batch number on the report with the one on your vial. The free COA Checker on this site runs the first three checks on a photo of the certificate.
