Thymalin

THE LONGEVITY PEPTIDE

A-6 Thymic Peptide Extract

Thymalin is one of the most studied thymic peptides, developed by Dr. Khavinson in Russia. It enhances T-cell production, balances immune responses, and has shown remarkable anti-aging effects in long-term studies - including increased lifespan in human trials. It works through epigenetic mechanisms to reactivate genes silenced by aging.
