It isn’t thymosin beta-4. Different molecule, different job. Thymosin Alpha-1 is a signal. A message. The kind of message your thymus is supposed to send to your immune system that basically says: “Wake up. Get smart. Run better surveillance. Do your job.” Your thymus is immune boot camp. It takes raw recruits—T-cells—and trains them to recognize self vs. other. Friend vs. foe. That’s the entire game.
