Thymosin Alpha-1

An immune regulating peptide used clinically in more than 30 countries.

What it is

Thymosin Alpha-1 is a natural peptide produced by the thymus gland, the organ that trains immune T cells.

How it works

It helps T cells mature and improves how the immune system recognises threats. Rather than pushing the immune system harder, published work describes it as steadying the response.

What it is researched for

  • Chronic viral infection
  • Immune support during illness
  • Vaccine response in older adults

Research status

Approved as a medicine in many countries for hepatitis B and C. Not approved in the US.

What to watch for

  • Injection site reactions
  • Caution with autoimmune conditions given the immune activity

Storage

Lyophilised powder keeps in the freezer or fridge, away from light. Once reconstituted with bacteriostatic water, keep it refrigerated and use it within about four weeks.

Common questions

Does it boost immunity?

The published description is regulation rather than boosting. It appears to help an underperforming response work properly.

How long do protocols run?

Clinical use typically runs in blocks of 8 to 12 weeks.
