Is Nextgen Labs legit? An independent review
Nextgen Labs markets its stock with the line 'UK-stocked, lab-tested compounds with 99%+ purity'. It names no testing laboratory and publishes no certificate to look at, so that claim cannot be traced back to anyone. A purity number a buyer cannot trace back to a laboratory is marketing, not evidence.

Is Nextgen Labs legit? The questions people ask
Is Nextgen Labs legit?
Nextgen Labs (nextgen-labs.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 Nextgen Labs publish a real, verifiable Certificate of Analysis?
Not one that can be independently verified in its own name. They claim 'third-party / lab tested' but never name the lab and publish no verifiable certificate, an unnamed, unpublished test is just a marketing claim.
How do I check Nextgen Labs's certificate myself?
Find the certificate on nextgen-labs.co.uk and read four things: an independent laboratory is named; the client field names Nextgen Labs, 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.
