Alternatives to Synedica Peptides in the UK: sellers you can actually verify

Synedica Peptides (synedicapeptides.co.uk) does not publish a certificate of analysis you can verify in its own name. If that is why you are looking for an alternative, the UK sellers further down do, so you can check the testing yourself before you buy. The Peptide Watch takes no vendor money and links to no seller's shop.

Why Synedica Peptides is on the watch list

Synedica Peptides sells retatrutide, tirzepatide and semaglutide pens and kits with GBP pricing, Royal Mail 24 and free delivery over £150. It names no laboratory on the product pages. It is part of a wider 'Synedica Verified Supplier' network (which also includes the already-listed jeopeptidesuk.co.uk) and that network advertises Janoshik elsewhere, but nothing verifiable is surfaced here.

• Why it is on the watch list: No named lab, nothing to verify
• Shared operator: the same operator also runs synedica-uk.shop, so comparing Synedica Peptides with those is comparing one seller with itself
