TD-1

TD-1 (Transdermal peptide) is a short peptide that can promote the delivery of macromolecule drugs, especially protein drugs, through the skin barrier. TD-1 can significantly improve the transdermal delivery efficiency of protein drugs such as insulin and human growth hormone, allowing them to reach systemic circulation. Research on TD-1 transdermal drug delivery system[1].
