Thymosin alpha-1
A thymus peptide that tunes T-cell and dendritic-cell function; one of the best-studied immune peptides.
Approved in 35+ countries as Zadaxin (hepatitis B/C, vaccine support); not FDA-approved.
Used for
- Chronic viral infections (hepatitis B)
- Immune support during illness or chemotherapy
- Better vaccine response in weak immune systems
How it works
Acts through toll-like receptors on immune cells to mature T cells and balance immune signaling, boosting weak responses without overdriving strong ones.
What the research shows
- Approved abroad for hepatitis B as an add-on; used in China in sepsis and severe infections.
- In a 361-patient sepsis trial (ETASS), 28-day deaths were lower with thymosin alpha-1 (26% vs 35%), a borderline result, with better immune markers.
Dosing
Dosing isn’t listed on the public site. In the app, each published option is shown with its source (a drug label, a clinical guideline, a trial or community reports) and can be turned into a protocol you review.
Work out the units to draw for your vial →Side effects
- Injection-site discomfort; generally well tolerated
Cautions
- Immune stimulation: talk to your doctor with an autoimmune disease or organ transplant.
Storage
Unmixed powder: freezer or fridge, away from light.
Once mixed with bacteriostatic water: fridge; the common rule is to use it within 28 days.
There is no label or published stability data for this one, so treat these as habits, not limits.
