The CEO of Bioviva USA Inc, Elizabeth Parrish, claims to be the first human in world history to have successfully reversed the effects of natural ageing - thanks to experimental gene therapy provided by her company.

Parrish first underwent gene therapy in 2015 - one designed to protect against muscle mass depletion that is inherent to ageing and another to fight stem cell depletion due to age-related diseases.

Originally meant to prove that her company's gene therapy was safe, the results - should they prove to be effective in the long-term and withstand due scientific scrutiny - would be the very first successful demonstration of telomere lengthening in any human.

"Current therapeutics offer only marginal benefits for people suffering from diseases of ageing. Additionally, lifestyle modification has limited impact for treating these diseases. Advances in biotechnology is the best solution, and if these results are anywhere near accurate, we've made history," Parrish notes.
