What is Thymosin Alpha-1?

Thymosin alpha-1 is a 28 amino acid peptide first isolated from the thymus, the gland where T cells mature. The version used in medicine is synthetic and identical to the natural sequence, and it has the largest human trial record of the immune peptides, studied since the 1970s and marketed abroad. Here it is prescribed after a free consultation and a review of your history.

Thymosin Alpha-1 benefits and uses.

  • Immune support

    It has decades of human trials in specific illnesses, where it was studied for organizing the immune response; general immune support in healthy adults has not been tested.

  • Recovery during serious illness

    Randomized human trials have studied it in severe infection and severe pancreatitis, alongside standard care.

  • 28amino acids, identical to the natural thymus peptide
  • 1970swhen human research on it began

How does Thymosin Alpha-1 work?

The thymus trains T cells, the immune cells that coordinate the body's response to infection and to abnormal cells. Thymosin alpha-1 appears to act on the receptors that shape how T cells and dendritic cells respond, nudging the immune system toward a more organized response. That is why it has been studied where the immune response is either insufficient or disordered.
