Alternatives to Synedica in the UK: sellers you can actually verify
Synedica (synedica-uk.shop) 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 is on the watch list
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.
- Why it is on the watch list: No named lab, nothing to verify
- Shared operator: the same operator also runs synedicapeptides.co.uk, so comparing Synedica with those is comparing one seller with itself
