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 and balances immune responses. Long-term human trials reported increased lifespan. It works through epigenetic mechanisms to reactivate genes silenced by aging.
