TB-500 is a synthetic N-acetylated heptapeptide (Ac-Leu-Lys-Lys-Thr-Glu-Thr-Gln) corresponding to the actin-binding fragment — residues 17–23 — of thymosin β4, a naturally occurring 43-amino-acid regulatory peptide. In published preclinical literature this LKKTETQ motif has been investigated for its role in actin sequestration, cell migration, and connective-tissue repair processes in animal and in vitro models. Supplied lyophilized at ≥99% HPLC purity with a per-lot Certificate of Analysis. For laboratory and research use only — not for human or animal consumption. ROEHN makes no claims regarding its effects.

Awesome service. Fast shipping.
Thank you, Ryan. We really appreciate you taking the time to leave a review. We work hard to process every order as quickly as possible while maintaining the level of care and attention to detail our customers expect. It is great to hear that your experience reflected that. Thank you for choosing ROEHN and for trusting us with your order. We truly appreciate your support and look forward to serving you again.
The only reason it is not 5 stars is because it took 2.5 weeks to get my order. Customer service is great.
