Nicolas Chernavsky is reproducing Harold Katcher's rat rejuvenation experiment. In the latest update he talks about the protocol, the timeline, and what the results could mean.

No other published study has achieved comparable results in a mammal. The experiment has not been independently reproduced. Nicolas & Nina have established the Rejuvenation Science Institute in Brazil to run an open replication of Katcher's study, in collaboration with UNICAMP. The experiment begins in April 2025. Rats will receive injections of PEPS — pig extracellular particles from young animals — and be assessed across five months using grip strength tests, memory tests, ten blood markers, and epigenetic clocks run by Steve Horvath's Clock Foundation. Nicolas walks through the full protocol, explains the key differences from the original study, and outlines when interim results will be available. Results will be published openly as they come in. ⏲️Chapters 0:00 Introduction — the most important unreplicated experiment in ageing science 1:05 What PEPS are and how they differ from standard exosome therapies 3:45 The full protocol: from pig plasma to rat injection 7:30 Why the experiment is starting two months earlier than planned 9:00 The rat groups: old treated, old control, and the young treated addition 11:50 The measurement approach: grip strength, memory, blood markers, epigenetics 15:20 Interim results timeline: what to expect month by month 19:30 The longevity extension phase: what happens if rejuvenation is confirmed 23:00 Horvath's epigenetic clock: why the foundation sends DNA to the US 27:15 Crowdfunding and collaboration: UNICAMP, Do Not Age, and Helis Foundation 33:00 Aging-by-signalling: why this experiment tests a fundamental theory of ageing 40:00 The embryo rejuvenation precedent — we know rejuvenation is biologically possible 46:30 Can we visit the lab?
