Recovery
TB-500 5mg
Animal models study its part in recovery, how wounds heal, how new blood vessels form, and how the body handles swelling. Research-grade TB-500 is a synthetic peptide drawn from thymosin beta-4, made for tissue-repair and cell-migration research. It covers the actin-binding region of the parent molecule.

How TB-500 is studied to work, in plain words
- TB-500 is a short lab-made piece of a much larger natural protein called thymosin beta-4.
- It has no receptor to plug into. Its job happens inside the cell.
- There it holds on to actin, the building material a cell uses to change shape and move.
- With more actin held in reserve, repair cells are studied for how quickly they reach a fresh injury.
- A 2026 review found almost every study written up as TB-500 research actually tested the parent protein.
These are findings investigators reported in laboratory studies, and in one registered trial of a different, larger molecule. They are not a result for this vial, and not a result for any reader. TB-500 is not approved by Health Canada or the FDA for any human or veterinary use, and everything Lux BioPure sells is supplied for laboratory research use only.

How it works, step by step
Step 1 of 3Actin, inside the cell
Step 1 · Target
Actin, inside the cell
- Actin is the frame a cell builds to change shape and crawl.
- A short sequence in TB-500, LKKTET, grabs loose actin and holds it in reserve.
- Studied for the pace at which a cell can rebuild that frame.
A pool of actin held ready
- Loose actin is held in reserve rather than used at once.
- That reserve sets the pace at which the cell can rebuild its frame.
Measured2026 review of 80 published studies: seventy tested the parent protein, one tested TB-500 itself, and it was not an injury study.Applied Sciences, 2026
Step 2 of 3Repair cells on the move
Step 2 · Target
Repair cells on the move
- With more actin on hand, repair cells are studied for how fast they travel.
- Nearly all of that work was done on the parent protein, not on TB-500.
- Studied for how fast repair cells reach a fresh injury, with new vessel growth measured alongside.
Travel to a fresh injury, and new vessels
- New blood vessel growth is measured alongside the cells that travel.
- The short piece sold as TB-500 is not what most of that work tested.
MeasuredThe same 2026 review: no human studies of either molecule in tendon, ligament, muscle, bone or spine repair, across all 80 studies.Applied Sciences, 2026
Step 3 of 3Wound repair, tested on the parent protein
Step 3 · Target
Wound repair, tested on the parent protein
- The full-length parent protein is the molecule that reached a registered trial.
- The parent protein, not this short piece, was the molecule tested.
- Studied in one registered human trial, on pressure ulcers, using the full-length protein.
The one registered human trial in this family
- It tested a gel of the full-length protein against a placebo.
- The short piece sold as TB-500 was not in that trial.

What is TB-500 5mg?
TB-500 is a synthetic version of Thymosin Beta-4, a natural 43-amino-acid peptide found in nearly all human and animal cells. Research centres on its part in actin binding and cell movement.
Animal studies have looked at TB-500's effects on wound healing, new blood-vessel growth, and swelling. It is often studied next to BPC-157 in paired tissue-repair protocols.
Supplied as lyophilized powder in a 5 mg vial, singly or as a 10-vial pack. Store at −20°C. It stays stable 24+ months when lyophilized and handled with care.

Research Profile
preclinical research consensus for informational comparison only
What arrives, and what to do with it
The vial ships lyophilized, a sealed powder, not a ready-to-use liquid. It needs bacteriostatic water and a clean workspace before it is usable in a protocol.
What's in the box
One sealed 5 mg vial of lyophilized powder, with its lot number printed on the label. The 10-pack is ten of that same vial. Bacteriostatic water is sold separately, so it goes in the order too if there is none on the bench.
Store cold, warm before opening
The label on the vial says it plainly: store in a cool, dark place. Lyophilized and handled with care it stays stable 24 months and more at -20°C, and a 2-8°C fridge shelf covers a shorter hold. Bring the vial to room temperature before opening, then reconstitute, refrigerate at 2-6°C and use within 28 days.
How to tell it went right
A properly reconstituted vial dissolves into a clear, colorless solution, with no cloudiness and no particles. If it does not, or if the lot on the vial does not match the report on our lab reports page, stop and contact us before it goes into a protocol.
Questions about TB-500 5mg
What is TB-500 studied for?
Laboratory work studies how it holds on to actin, the building material a cell uses to change shape and move. A 2026 scoping review in Applied Sciences found 80 published studies covering TB-500 and its parent protein together, of which 70 tested the parent protein and one tested TB-500 itself. Those are laboratory findings, and not a result for this vial.

Has TB-500 been studied in people?
No, and the one registered human trial in the family tested a different molecule. A gel made from full-length thymosin beta 4 was compared against a placebo, a dummy treatment with no active drug in it, in 72 patients with pressure ulcers, and it performed no better than the placebo on wound repair.

How is TB-500 different from BPC-157?
They come from different places and act in different ways. TB-500 is a short lab-made piece of thymosin beta-4 and works inside the cell, holding actin in reserve. BPC-157 is a 15 amino acid chain copied from a protein in stomach fluid, and it acts on the signals behind new blood vessels.
Is TB-500 legal to buy in Canada for research?
Research peptides sold only for in vitro laboratory use sit in a legally distinct category from approved drugs, and that is the category this vial is sold in. Health Canada classifies a substance by marketing intent under the Food and Drugs Act, not by molecular structure, and Canada runs no licensing registry for research chemicals. TB-500 holds no Drug Identification Number.
How is each batch tested?
An independent lab, Janoshik, runs HPLC and mass spec on every batch before it goes on sale. The report is published under the lot number printed on the vial label, so the two can be matched on arrival. The HPLC purity recorded for this product is 98%+.
What arrives in the box, and how is it stored?
One sealed 5 mg vial of lyophilized powder, with its lot number printed on the label. Lyophilized and handled with care it stays stable 24 months and more at -20°C, and a 2-8°C fridge shelf covers a shorter hold. Once reconstituted it is refrigerated at 2-6°C and used within 28 days.
Is TB-500 for human use?
No. Everything Lux BioPure sells is supplied for laboratory research use only, not for human or veterinary use, and not to diagnose, treat, cure or prevent any disease. TB-500 is not approved by Health Canada or the FDA for any human or veterinary use.
