What we found

Proforma Peptides is the cleanest of the non-Janoshik sites: it commissions genuine Certificates of Analysis from Analiza Białek, a real independent lab, with itself as the client. The only mark against it is that it's Analiza, not the Janoshik standard this index is built on, so it sits just outside the independently-tested list rather than among the bad actors. Aggravating: the reports seen are dated September 2025 and served from personal Dropbox links.

The certificate, and what's wrong with it

Certificate displayed by Proforma Peptides

Analiza Białek, real lab, not Janoshik

What this certificate actually is: A genuine Analiza Białek report that names Proforma Peptides itself as the client (5-Amino-1MQ, 99% purity, batch 2567), so this is real independent testing in the seller's own name, just from Analiza, not the Janoshik standard this index is built on. The test dates, highlighted on the certificate, are 24 to 25 September 2025., client field: Proforma Peptides

⏳ This certificate is dated Sep 2025, 10 months old. A Certificate of Analysis only covers the single batch that was tested. Unless the seller has re-tested since, the stock you'd receive today is unverified, or it has sold the same batch for 10 months, which for a peptide is not credible.

Proforma Peptides reviews: what others report

Third-party signals we found, reviews, independent tests and platform actions, each attributed to its source and labelled by how well it is corroborated. This is not our own verification; items marked "single / unverified report" are unconfirmed and should be treated with caution.

reported

A reviewer reports a scam where a contact named 'Jan Malessa' claimed connection to Proforma Peptides, took payment for weight-loss products and never delivered; Proforma replied that this impersonator is not associated with them, they do not ship outside the UK, and the only legitimate sites are proformapeptides.co.uk/.com. This concerns impersonation of the brand rather than the official vendor's own conduct.

“Contact person Jan Malessa - claiming connection to Proforma Peptides - offer weight reduction products. After payment no products arrives and you're ghosted.”

single / unverified report

Scam Detector's automated validator reportedly assigns proformapeptides.co.uk a low trust score (around 36.9); this contrasts with the strong Trustpilot aggregate and is an algorithmic signal only.

Questions people ask about Proforma Peptides

Is Proforma Peptides legit?

Proforma Peptides (proformapeptides.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 Proforma Peptides publish a real, verifiable Certificate of Analysis?

Not one that can be independently verified in its own name. Commissions genuine COAs from Analiza Białek (a real independent lab) with itself as client, clean, but not the Janoshik standard.

How do I check Proforma Peptides's certificate myself?

Find the certificate on proformapeptides.co.uk and read four things: an independent laboratory is named; the client field names Proforma 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.
