This is plain-language harm-reduction information, not medical advice. Peptides discussed here are research compounds; most are not approved for human use. People will use them either way — we would rather they have the facts.
What it is
Thymosin alpha-1 is a natural hormone produced by the thymus gland. It supports the maturation of T-cells — a major arm of the adaptive immune system.
It is an approved medicine in many countries (sold as Zadaxin) for hepatitis B and as an adjunct for various infections and immune conditions.
History
Isolated from the thymus in the 1970s. Approved as a medicine in over 30 countries from the 1990s onwards.
How it works
Stimulates T-cell maturation and activity. Modulates both arms of immune response (innate and adaptive) without being broadly immunosuppressive or immunostimulatory.
Dosage
- 1.6 mg twice weekly (the approved Zadaxin dose).
- Wellness protocols often use 1.5–3 mg twice weekly for 4–8 week courses.
How it is taken
- Subcutaneous injection.
How to reconstitute
- 5 mg vial with 2 ml BAC water = 2.5 mg/ml. 1.6 mg = 64 units on a 1 ml insulin syringe.
How it should arrive
White powder, sealed vial.
How it should look once reconstituted
Clear colourless solution.
What to expect, and when
- Immune-related effects (frequency of colds, recovery from illness): 4–8 weeks.
Side effects
- Generally well tolerated.
- Occasional flu-like symptoms during initial dosing.
Risks
- Caution in autoimmune disease — anything modulating immune function can in theory shift things either way.
Potential gains
- Improved immune resilience.
- Faster recovery from infections.
- Useful adjunct for chronic infections under medical supervision.
