01The basics
What Thymosin 10mg is
This vial contains 10 mg of thymosin alpha-1, a peptide originally isolated from the thymus gland, where immune T-cells mature. It’s freeze-dried for mixing with bacteriostatic water.
Under the name Zadaxin, thymosin alpha-1 is approved in a number of countries, though not in Canada or the US, for chronic hepatitis B and C and as an immune booster alongside vaccines. It has one of the better safety records among peptides. Here’s what it does.
02Molecule
The molecule
What is actually in the vial or tablet, from the public chemistry databases of the U.S. National Library of Medicine.
03How it works
How it works
- Supports T-cell maturation and function, part of the body’s adaptive immune response.
- Boosts natural killer cells and helps regulate cytokines, the immune system’s chemical messengers.
- Short-acting: a half-life of about 2 hours, but its effects on immune cells last longer, so it’s given a couple of times a week.
04Half-life
Half-life, in plain numbers
A half-life of about 2 hours means half of what is in the body is gone after that time, then half of the rest, and so on. For an injected peptide it reflects how quickly the body breaks the chain down and clears it.
- One half-life
- 2 h
- About 97% gone
- 10 h
- Levels level out with regular use after
- 8 h–10 h
A textbook model built from the half-life alone. Real numbers vary from person to person.
05Clinical reference
Dosing information
Clinical reference. Where thymosin alpha-1 (Zadaxin) is approved, the usual dose for hepatitis B is 1.6 mg injected under the skin twice a week for 6 months.
Talk to a doctor before use.
Mixing math. Adding 2 ml of bacteriostatic water to the 10 mg vial gives 5 mg per ml. On a U-100 insulin syringe:
- 1.6 mg = 0.32 ml = 32 units
The vial holds about six 1.6 mg doses, three weeks at twice a week.
06Mixing
Mixing and storage
- Bacteriostatic water and syringes are sold separately; see Pairs well with below.
- Add water slowly and swirl gently until clear.
- Store in the fridge (2–8 °C) and don’t freeze once mixed.

08Injection sites
Where it is injected
Thymosin 10mg arrives as a freeze-dried powder. After it is mixed with bacteriostatic water it is normally injected under the skin, into the fat layer, with a short insulin needle.
1Belly (abdomen)Fat under the skin of the bellySubQ
- Pick a spot at least 5 cm (two finger-widths) from the belly button.
- Avoid scars, stretch marks, bruises and the waistband.
- Pinch up a fold of skin and inject into the fold.
Why it is used. The most fat to work with, easy to see, and the steadiest absorption. Weekly pen medicines list it first.
Careful. Move each injection at least 2–3 cm from the last to avoid firm fatty lumps (lipohypertrophy).

2Front of thighFat under the skin of the thighSubQ
- Sit and look down at the front of your thigh.
- Use the middle band: a hand-width below the hip crease and a hand-width above the knee.
- Pinch the skin and inject into the fold.
Why it is used. Easy to reach while seated, and a handy second area to rotate with the belly.
Careful. It can absorb a little more slowly than the belly; hard leg training straight afterwards can speed it up.

3Back of upper armFat over the tricepsSubQ
- Find the soft, fleshy area at the back of the upper arm.
- Stay halfway between the shoulder and the elbow.
- Pinch the skin and inject into the fold.
Why it is used. A third area to rotate through, so every spot gets a longer rest.
Careful. Hard to pinch and reach with one hand; most people need a helper.

Route for Thymosin 10mgUnder the skin (subQ)
- Start with the bellyIt has the most fat and the steadiest absorption, and you can see what you are doing. The thigh and arm are there to rotate into.
- Short needle, small volumeAround 1 ml or less per spot. A 4–13 mm insulin needle reaches the fat without touching muscle; pinch up the skin if you are lean.
- New spot every timeShift 2–3 cm from the last injection. Reusing one spot causes firm lumps that absorb unevenly.
- Wash your hands
- Alcohol on the stopper and skin, let it dry
- New sterile needle and syringe every time
- Never share any of it
- Sharps into a puncture-proof container
