Antiaging gene therapies to overexpress TERT and Follistatin were used in a mouse model. The mice saw a 41 and 32% increase in median life span. The study also used a novel viral vector, cytomegalovirus for the delivery.
Liz Parish of Bioviva has treated herself with all of these antiaging gene therapies.
If humans experienced the same antiaging effect as the mice then humans would live to a median age of 100 with these treatments.
