## Key facts
- Retatrutide has no marketing authorisation in the UK, the US, the EU or anywhere else — there is no legal supply chain on Earth.
- Anything sold as “retatrutide” — vials, pens, “research peptides” — is an unlicensed product, illegal to supply for human use in the UK.
- The one-line test: a genuine product cannot be for sale before authorisation. That single fact settles every listing.
- Independent testing of grey-market GLP-1 products has repeatedly found wrong doses, contamination and entirely different substances.
- Already bought or used it? Do not inject, report the seller via the MHRA Yellow Card scheme, and use NHS 111 or 999 if you feel unwell.
