TB-500 10mg research vial
TB-500 10mg research vial: LKKTETQ, the 7 amino acid stretch taken from the 43 amino acid protein thymosin beta-4, not the whole protein, for 5,600,000 VND ($220 USD).
For TB-500, this page sums up one human trial paper (2015), one review (2018), two animal studies (2012 and 2025) and one lab analysis (2022) from PubMed, three of them on TB-500 itself and two on the whole thymosin beta-4 protein; the page flags which studies used the larger protein instead.

The 7 Amino Acid Cut of Thymosin Beta-4
The vial holds TB-500. Thymosin beta-4 is the larger molecule it comes from, a 43 amino acid protein most human cells make. TB-500 keeps just 7 of those 43, the LKKTETQ stretch, with an acetyl group capping one end.
Researchers tie that stretch to cell movement. Mixing up the two molecules is a frequent reading error in this field, so each line below says which one a study used.

A Short Research List
A short list, and only some of it uses TB-500 itself.
What to weigh: Only the eye gel study, the horse test and the product check concern TB-500 itself. The human trial and the heart review are about the larger protein it comes from, which is six times longer.
- Animal study, 2012 Model: horse blood and urine samples, for racing checks.Measured: whether a new lab method could detect TB-500, built because the peptide was being misused in racing.
- Animal study, 2025 Model: animals with burned eye surfaces, in a study of a gel made with the TB-500 sequence.Measured: repair of the eye surface over time.
- Human trial, 2015 Who: 9 people with severe dry eye, given the full thymosin beta-4 protein, not TB-500.Design: phase 2, randomized, against a placebo.Measured: eye discomfort and the signs of dry eye.
- Review, 2018 Scope: the whole thymosin beta-4 protein in the heart.Based on: animal research, with new blood vessel growth as the main theme.
Label accuracy is a known issue for this compound. A 2022 lab test of TB-500 products bought online found contents that did not always match the label.

Buyer Questions About TB-500
What are the differences between peptides TB-500 and BPC-157?
TB-500 is a 7 amino acid piece of thymosin beta-4, a protein most cells make. BPC-157 is a 15 amino acid chain whose sequence was first reported from a protein in gastric juice. They are separate molecules with separate studies.Is TB-500 the same molecule as thymosin beta-4?
No. TB-500 is a 7 amino acid slice of a 43 amino acid protein, so studies of the whole protein are not TB-500 studies.Has TB-500 itself been given to people in a study?
Not in this summary. Its one human trial used the whole thymosin beta-4 protein, in 9 people with severe dry eye.Why was a horse racing test written for TB-500?
Because the peptide was being misused in racing, a 2012 paper built a lab method to find it in horse blood and urine.How much is a pack of 10 TB-500 vials?
33,600,000 VND ($1,320 USD) for ten TB-500 vials, so each one comes to 3,360,000 VND ($132 USD).
