In people

When people take Thymosin Alpha-1, CD4 and CD8 T-cell counts rise and natural killer cell activity strengthens within weeks. People with chronic viral infections see viral load drop and liver enzymes settle. Older people make more antibodies after vaccines. In severe infection and sepsis the immune system recovers its balance and its counts sooner. People most often describe fewer infections, shorter colds and a lift in energy as the immune system stops running in the red. It is very well tolerated, with mild redness at the injection site the most common effect.
