Cycloastragenol is a triterpenoid isolated from various legume species in the genus Astragalus that is purported to have telomerase activation activity. A preliminary in vitro study on human CD4 and CD8 T cells found that cycloastragenol may moderately increase telomerase activity and inhibit the onset of cellular senescence.

==History== Cycloastragenol was patented by Geron Corporation and sold to Telomerase Activation Sciences in early 2013 who are developing it as a product named TA-65. Bill Andrews of Sierra Sciences has done testing on the anti-aging aspect of TA-65;, as well as Maria Blasco in the journal Aging Cell, finding no increase in murine median or mean lifespan but some physiological anti-aging effects without augmenting cancer incidence. TA sciences was served with a consent order by the Federal Trade Commission for deceptive advertising implying that TA-65 can reverse aging and repair DNA damage.
