Selected sources reviewed
The thymosin beta-4 17–23 fragment is a seven-amino-acid region. The TB-500 material characterized in the cited analytical paper is its N-acetylated form, acetyl-LKKTETQ.[1]
Identity checks
A fragment is not full-length, 43-amino-acid thymosin beta-4. Verify whether a listing specifies the same sequence and acetylation as the cited material.[1][2]
Analytical study; human evidence gap
The reviewed study identified and measured the fragment in equine doping-control research. It was not a human treatment trial. FDA reports that it has not identified human-exposure data for this fragment in its compounding assessment.[1][3]
Regulatory context
The FDA compounding safety assessment specifically names the LKKTETQ fragment. It does not establish product approval or import permission.[3]
