About TB-500 as a research compound
TB-500 is a research-grade synthetic peptide based on the bioactive central region of Thymosin Beta-4, a 43-amino-acid actin-sequestering protein found throughout mammalian tissues. The TB-500 fragment retains the LKKTETQ actin-binding motif that drives much of Thymosin Beta-4's documented activity in tissue-repair, angiogenesis, and cell-migration models.
Research applications span tendon and ligament repair studies, cardiac infarct recovery models, corneal wound healing, hair follicle growth research, and inflammation-modulation work. TB-500 is frequently used alongside BPC-157 in synergistic-pathway studies, and Peptx stocks a pre-formulated BPC + TB blend for laboratories running combined studies.
All TB-500 ships as lyophilised powder under inert atmosphere with desiccant. Recent independent laboratory results are published in the COA Library.
