Psilocin reportedly extended human fibroblasts’ replicative lifespan in lab tests

A post citing a 2025 npj Aging study says psilocin, which the body produces from psilocybin, extended human skin fibroblasts’ replicative lifespan by 51% in lab tests. Lung fibroblasts took 57% longer to reach the point where they stop dividing. The post also says 80% of aged female mice given monthly psilocybin were alive after 10 months, compared with 50% of untreated mice.
