Selected sources reviewed
TB-500 requires an identity check: an analytical study uses that name for an acetylated seven-amino-acid fragment, while full-length thymosin beta-4 has 43 amino acids. These are different substances.[1][2]
Identity checks
The studied TB-500 fragment is acetylated LKKTETQ, corresponding to thymosin beta-4 residues 17–23. Confirm sequence and modification instead of equating every TB-500 label with full-length thymosin beta-4.[1][2]
Identity and analytical evidence reviewed
The fragment paper describes detection in equine samples. A separate human eye-drop trial studied full-length thymosin beta-4. Analytical detection is not evidence of therapeutic benefit; findings for full-length ophthalmic thymosin beta-4 cannot validate a fragment sold under the same informal name.[1][3]
Regulatory context
FDA’s compounding safety entry concerns the LKKTETQ fragment, also called TB-500, and identifies a human-exposure evidence gap.[4]

Research searches — not supporting citations
Search results may include unrelated records. A search link does not establish that a matching study exists.
These selected sources describe named substances and studied formulations. They do not authenticate a supplier, a certificate of analysis or the contents of a particular lot, and do not provide instructions for use. “Healing” and other catalogue categories are navigation labels, not evidence of efficacy or treatment recommendations.

TB-500 vs thymosin beta-4: why peptide identity matters
Understand the difference between the LKKTETQ fragment and full-length thymosin beta-4, and why their research cannot be treated as interchangeable.

TB-500 price: questions
Automated price sources are scheduled daily; other sources are checked manually. Check the offer's last successful source timestamp. A code is shown when it is attached to an offer or affiliate link. The displayed price includes a discount only when that code is cart-verified and the discounted price is explicitly recorded; otherwise it is the vendor's listed price. Prices exclude shipping. Stock status is captured at the same time. Rankings are by displayed price only. PeptideTech earns a commission when you buy through a link; it never changes the order.
