What we found
Rppeptides tells buyers 'Trusted sourcing Every product we retail comes fully tested, with COA's provided (Certificates of Authority)'. The certificate behind it is the raw-material factory's own QC sheet, not an independent test of what this seller ships. A factory QC document reused as a certificate proves the factory's sample, not this seller's vial.

Questions people ask about Rppeptides
Is Rppeptides legit?
Rppeptides (rppeptides.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 Rppeptides publish a real, verifiable Certificate of Analysis?
Not one that can be independently verified in its own name. What they show is the Chinese factory's own QC sheet (literally 'complies with the manufacturer's standard'), rebranded with their logo, the maker grading itself, not independent testing.
How do I check Rppeptides's certificate myself?
Find the certificate on rppeptides.co.uk and read four things: an independent laboratory is named; the client field names Rppeptides, 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.
