Anti-Aging cocktail tested in older smokers

This early-stage study tests whether combining exercise, a natural supplement called spermidine, and either rapamycin or lamivudine is safe and doable for current or former smokers aged 65-80. The goal is to see if this mix can reduce inflammation and slow aging. Only 22 participants will be enrolled, and the main focus is on safety and whether people can stick with the program.
