Manufacturer statement
Batch-specific COA (batch 57080) from Together Health Ltd, signed by the manufacturer's own QA (Bob Clough), states "Analysis performed by a 3rd party lab, accredited by UKAS" but does not name the lab. Read directly: no identifiable independent lab, so recorded as manufacturer-provided COA rather than verified independent lab testing.
