Overview

TB-500 is a synthetic fragment of thymosin beta-4, a protein involved in cell movement and tissue repair.

How it works

Thymosin beta-4 binds actin, a structural protein cells use to move. Research suggests it helps cells migrate into injured tissue; the short fragment is thought to carry that activity.

Clinical reference

There is no approved human dose. Thymosin beta-4 itself was tested as eye drops and wound gels, not as injections like this.

Label and guideline amounts are shown for reference only. They are not a recommendation, and we never give cycle or performance amounts. Any use belongs under a doctor’s care, with bloodwork.

Injection sites

TB-500 5mg is a freeze-dried powder. After mixing with bacteriostatic water, compounds like this are usually injected subcutaneously (subQ): into the fat just under the skin with a short insulin needle.

Commonly usedAnatomy drawing: OpenStax & Tomáš Kebert, umimeto.org, CC BY-SA 4.0, recoloured.

Volume per site: About 1 ml or less
Needle: 4 to 13 mm insulin needle, 29 to 31G

Finding it. Anywhere on the belly at least 5 cm from the navel, avoiding scars and the belt line. Pinch a fold of skin and inject into it.

Why it is used. The most-used subcutaneous site: easy to see, plenty of fat and steady absorption. Weekly GLP-1 pens list it first.

Watch out. Move each injection 2 to 3 cm from the last to avoid hard lumps.

Why these sites for TB-500 5mg

Subcutaneous (subQ)

Belly first. The abdomen has the most fat and the steadiest absorption, and you can see what you are doing.
Short needle, small volume. About 1 ml or less per spot with an insulin syringe. Pinch the skin if you are lean.
Move every time. Keep each injection 2 to 3 cm from the last to avoid lumps.

Every time: wash your hands, wipe the vial stopper and skin with alcohol, use a new sterile needle and syringe, and never share. See a doctor for spreading redness, heat, swelling, pus, fever or numbness. This is general guidance from standard nursing practice, not medical advice; a pharmacist or nurse can show you in person.
