Core Framework & Diagram The Future of Immune Rejuvenation

A trial combining growth hormone, DHEA, and metformin measurably grew the thymus back and reversed biological age by about 2.5 years — the first proof this is possible past middle age. Full lab-grown replacement thymuses are still 15+ years away.

Senescent cells refuse to die and constantly leak inflammatory signals. A short, intermittent course of two combined drugs cleared these cells from human patients in 2019, lowering inflammation and improving physical function — but this requires medical supervision, not self-dosing.

A partial version of the Nobel-winning cell-reset technique has already restored vision in old mice without triggering cancer — the long-term goal is reverting aged immune cells to a ‘young, highly active’ state directly. Still years from human safety trials.
