TB-500

Actin-sequestering research analogue. Commonly paired with BPC-157. Loading then weekly maintenance.

What it does / how it works

A lab analogue of thymosin beta-4. It binds G-actin so cells can move, build new vessels and close tissue. Loading then weekly maintenance matches how repair research is usually run. WADA banned.

Class	Thymosin β4 analogue
Typical vial	5 or 10 mg
Reconstitution	2 mL BAC per 10 mg = 5 mg/mL
Storage after mix	2–8°C, use within 28 days

Protocol

Goal	Dose	How often	How long	Route
Weeks 1-4 load	2.0-2.5 mg	Monday and Thursday	4-6 weeks	SubQ
Weeks 5-8 maintain	2 mg	Once weekly	4-6 weeks	SubQ
Off	None	Stop	2-4 weeks off	–

Watch: WADA prohibited. Do not treat a 10 mg vial as one daily dose.

TB-500 FAQ — Australia

Where can I buy TB-500 in Australia?

ELV8 Labs offers TB-500 in 10 mg vials with independent third-party testing at a leading Australian university. For research purposes only.

Is TB-500 the same as Thymosin Beta-4?

Yes. In commercial peptide supply, TB-500 refers to full-length Thymosin Beta-4 — a 43-amino acid peptide. This is standard across the industry in Australia and internationally. There is no truncated “TB-500 fragment” commercially available.

What is the difference between TB-500 and BPC-157?

TB-500 (Thymosin Beta-4) and BPC-157 are distinct peptides with different mechanisms. TB-500 works primarily through actin regulation and cell migration, while BPC-157 influences growth factor expression and angiogenesis through different pathways. They are frequently combined in research — see the Wolverine Stack protocol.

How often should TB-500 be administered in research?

Published protocols typically use 2–3 administrations per week during a 4–6 week loading phase, then once weekly for maintenance. This is less frequent than BPC-157 due to the longer observed half-life in test subjects.

Should TB-500 be injected locally or systemically?

Published research generally administers TB-500 via systemic subcutaneous injection (e.g., abdominal), unlike BPC-157 which is often injected near the site of interest. Thymosin Beta-4’s systemic distribution means local injection is not considered necessary in most research protocols.
