the fragment is typically described as covering residues around 1723 (the LKKTETQ motif) with a vendor-quoted molecular weight in the ~1.62.0 kDa range, but no 20232026 primary structural paper specifically validates "TB-500" as a defined chemical entity [5][9]
During this absorption window, blood flow to the injection site directly affects how much peptide reaches systemic circulation and how much remains concentrated locally
