Last year information was released concerning rejuvenation of the thymus which resulted in a reversal of the epigenetic clock an average of 2.5 years in a small trial of 9 people costing $10,000 per person. You can get this done too. A company has formed called Intervene Immune which will take on volunteers for the process. It is not funded so you would have to pay out pf pocket though eventually the cost may come down and they can provide financing. You do not have to travel to California to get this done. Cost prohibits me, and I may or may not be eligible as I have IBS though that is not on the exclusion list. I emailed them concerning all this which is how I got the information.

The TRIIM-X trial is an expanded pilot clinical study that will evaluate a personalized combination treatment regimen for thymus regeneration. The thymus is a part of the immune system that declines markedly with age, and regenerating it may prevent or reverse key aspects of immunosenescence (immune system aging) and potentially prevent or reverse key parts of the aging process more generally. The study will evaluate biomarkers for epigenetic aging and immunosenescence, as well as evaluate established clinical measures and risk factors for prevention of physical frailty, cancer, cardiovascular disease, diabetes, dementia, and also infectious diseases, including flu and COVID-19.
