01The basics
What TB500 5mg is
TB-500 is a synthetic peptide based on the active region of thymosin beta-4, a protein found in almost every cell in the body that helps cells move and organize their internal scaffolding. Each vial contains 5 mg of freeze-dried powder for mixing with bacteriostatic water.
It’s widely used for recovery from injuries, often alongside BPC-157. The supporting evidence comes from animal studies and from trials of the full thymosin beta-4 protein, not TB-500 itself. It isn’t approved as a medicine. Here’s what’s known and what isn’t.

03How it works
How it works
- Binds actin, a building block of the cell’s skeleton, which helps cells migrate to injury sites.
- Supports new blood vessels and reduces inflammation in animal models of heart, skin and eye injury.
- TB-500 versus thymosin beta-4: TB-500 is a short fragment; most published research used the full protein, so results may not carry over.
04Clinical reference
Dosing information
Clinical reference. TB-500 has no approved or trial-established human dose.
Talk to a doctor before use.
Mixing math. Adding 2 ml of bacteriostatic water to the 5 mg vial gives 2.5 mg per ml. On a U-100 insulin syringe:
- 0.5 mg = 0.2 ml = 20 units
- 1 mg = 0.4 ml = 40 units
- 2.5 mg = 1 ml = 100 units
05Mixing
Mixing and storage
- Bacteriostatic water and syringes are sold separately; see Pairs well with below.
- Add the water slowly down the side of the vial and swirl gently until clear.
- Keep unmixed and mixed vials in the fridge (2–8 °C), away from light.
- Don’t freeze a mixed vial.

07Injection sites
Where it is injected
TB500 5mg 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 TB500 5mgUnder 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

08Risks
Side effects and risks
Short-term side effects appear uncommon, but human data for TB-500 itself is essentially absent.
Little human data
No controlled human trials of TB-500 have been published.
Cancer question
Thymosin beta-4 promotes cell migration and blood vessel growth, and higher levels have been found in some tumours. Whether TB-500 affects cancer risk is unknown.
Fatigue and headache
Occasionally reported by users after injections.
Injection sites
Redness or soreness. Use sterile technique and rotate sites.
Banned in sport
TB-500 is on the World Anti-Doping Agency’s prohibited list, and racehorse trainers have been sanctioned for it.
Don’t use it if you
Have active cancer or a history of it, are pregnant or breastfeeding, are under 18, or compete in tested sport.
09Interactions
Interactions
Medicines and substances that change how this product behaves, or that it changes. Show this list to your pharmacist along with everything else you take.
- Good to knowNo interaction studies
This peptide has not been through the drug-interaction testing that approved medicines go through, so nothing is known for certain.
- CautionCurrent or past cancer
Thymosin beta-4 promotes blood vessel growth and cell migration in lab studies, a concern for anyone with a history of cancer.
10Safety
Before you use it
- Get a diagnosis for any significant injury; some need imaging or surgery.
- Keep up physiotherapy: loading is what remodels tendons and ligaments.
- Use sterile supplies for every draw and injection.
- Tell your doctor what you’re using.

13Questions
Common questions
TB-500 or BPC-157?
They’re thought to work differently: BPC-157 on blood vessel growth and growth hormone receptors, TB-500 on cell migration. Many people use both, but neither has strong human evidence.
Is TB-500 the same as thymosin beta-4?
No. TB-500 is a synthetic fragment of thymosin beta-4. Most of the research was done on the full protein.
Where is it injected?
Usually under the skin. There’s no good evidence that injecting near the injury works better.
How fast is shipping in Canada?
Orders ship by Canada Post Xpresspost, with tracking within 72 hours of payment, with tracking.
Is TB-500 legal in Canada?
TB-500 isn’t approved by Health Canada as a drug and isn’t a controlled substance.
How is my order packaged?
In a plain, unbranded box with no product names on the outside.
