It cites the Dunedin Study, cellular senescence, epigenetic clocks, the TRIIM trial and a lifestyle study, and announces an 8-week protocol. [1]
The description says the Dunedin Study tracked 38-year-olds with biological ages from 30 to 60, citing Belsky et al. (2015). [1]
The description presents the TRIIM trial as how science first reversed human aging, linked to thymus regeneration. [1]
