Not claimed

"Resemblance to studied formulations" describes how closely this product's extract, form and dose match preparations used in published research - it is not a claim that the product itself has been clinically tested, and it does not mean the product "works" for any individual.

Manufacturer states 500mg of high-potency ashwagandha extract per vegetarian capsule, “standardised to provide a guaranteed level” of withanolides – the specific percentage is not disclosed on the listing. 1 capsule daily, 60 capsules.

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.
