TA-65 (Telomerase Activator Peptide Context)
A commercial nutraceutical whose active constituent, cycloastragenol from Astragalus, is a small molecule, not a peptide.
Overview
TA-65 is a commercial nutraceutical described as a telomerase activator. It is not a peptide; its active constituent is cycloastragenol, a small-molecule saponin derivative from the root of Astragalus membranaceus (milk vetch), marketed in capsule form under a proprietary brand. The peptide context in the listing name is a marketing framing rather than a description of the product chemistry.
Mechanism
Cycloastragenol is reported to activate telomerase, the enzyme that extends telomeric DNA, in cell-based assays. Company-sponsored work reported lengthening of short telomeres in some users, but independent replication is limited, and effects on human health span are unproven.
Expected Effects
- Increased telomerase activity in vitro and in some ex vivo studies
- Company-sponsored pilot data reported changes in measured telomere length in subsets of users
- Claims of anti-aging benefit lack independent clinical confirmation
Side Effects & Tolerability
As a botanical-derived supplement it is generally regarded as well tolerated, though published safety data are limited. The consequences of sustained telomerase activation remain a theoretical concern under investigation.
Storage
Store per the supplement label, in a cool, dry place, away from direct sunlight.
