Thymulin
THE THYMUS REJUVENATOR
Facteur Thymique Sérum (FTS), Thymic Serum Factor
Thymulin is a natural hormone produced by your thymus gland that declines with age. It's essential for training and maturing your T-cells, the soldiers of your immune system. By supplementing thymulin, you can help restore youthful immune function, reduce excessive inflammation, and support recovery from illness or chemotherapy. It requires zinc to work properly.
