The method & evidence

BPeer-reviewed validation

Provisional method assessment: peer-reviewed studies associate the published Phenotypic Age model with mortality and morbidity. A complete independent-replication review is pending; no product benefit is implied.

Our grade evaluates the measurement method. It does not grade customer service, personal results or whether buying the product improves health. Read the framework.
