Our goal is to reverse the human aging process and cure diseases linked to aging by activating telomerase and thus extending telomeres, leading the cells to return to a state of youthful gene expression and function.

Defytime Group

Defytime is a corporate group and a brand. Our operation is headquartered in Auckland New Zealand, with labs co-located in The University of Auckland and research and development with Sierra Sciences, LLC, in Reno, Nevada USA. Our first anti-aging clinic is located in Vanuatu.

The strongest telomerase inducer identified so far from the research of Bill Andrews, Ph.D. and Sierra Sciences is CO314818. We have done additional medicinal chemistry with the compound to develop TAM, which we combine with proven ingredients to create our range of beauty and aging care products.

Part of the proceeds of our sales go toward furthering Dr. Bill Andrews’ telomere research.
