◇ The Peptide Watch, independent vendor audit

Is Synedica legit? An independent review

synedica-uk.shop · audited 10 October 2026
Synedica is on the watch list: its certificate can't be verified in its own name, one of 459 of 500 UK sellers that fail this check.

Synedica (synedica-uk.shop) is the brand's storefront selling Synedica-branded retatrutide, semaglutide and NAD+ with GBP pricing, a UK phone line and free UK shipping, but names no laboratory and publishes no verifiable certificate. Same brand as synedicapeptides.co.uk.

This is one of 2 storefronts run by the same operator. The same people also run: synedicapeptides.co.uk. (same Synedica brand and operator.)
"Shopping around" between these names is buying from one seller, same stock, same risk, different branding.

Is Synedica legit? The questions people ask

Is Synedica legit?

Synedica (synedica-uk.shop) 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 Synedica publish a real, verifiable Certificate of Analysis?

Not one that can be independently verified in its own name. ⚠ No lab named. Synedica's brand storefront sells its own-branded retatrutide, semaglutide and NAD+ but names no laboratory.

How do I check Synedica's certificate myself?

Find the certificate on synedica-uk.shop and read four things: an independent laboratory is named; the client field names Synedica, 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.
