^{【Product Overview】}

^{We are a specialized global supplier of Transdermal Peptide (TD-1), a specific 11-amino acid cyclic peptide designed to revolutionize drug delivery. Unlike standard surfactants that damage the skin, TD-1 works via a specific biological mechanism (interacting with the Na+/K+-ATPase beta-subunit) to create transient, reversible openings in the epidermal barrier. We provide this cutting-edge excipient peptide to pharmaceutical formulators and cosmetic researchers aiming to deliver macromolecules (such as Insulin, Growth Hormone, and GLP-1) via topical application, eliminating the need for injections.}

^{【Key Advantages】}

^{Needle-Free Delivery Solution: TD-1 is the key to unlocking "Topical Bioavailability". Research demonstrates that co-administration of TD-1 allows large hydrophilic molecules (which normally cannot cross the skin) to reach systemic circulation via simple creams or gels.}

^{Specific Mechanism: It selectively binds to the C-terminus of the Na+/K+-ATPase β-subunit. This interaction modulates the skin's tight junctions transiently, enhancing permeability without causing the permanent skin damage or irritation associated with chemical enhancers (like DMSO).}

^{Versatile Carrier: It is widely researched as a co-factor for delivering a broad range of actives, including siRNA, Insulin, hGH, and Exenatide. This makes it an invaluable tool for developing "Patient-Friendly" formulations.}

^{High Purity & Safety: We guarantee ≥95.0% purity (HPLC). Our cyclic peptide structure (Cys2-Cys10 disulfide bridge) ensures stability in formulation bases, providing a consistent enhancement effect.}

^{【Logistics & Service】}

^{Formulation Support: TD-1 is a functional excipient. We can provide technical guidance on the optimal molar ratios (peptide-to-drug) required to achieve maximum skin penetration.}

^{Global Export: We are experienced in shipping functional peptides globally. We provide full HS Code support (typically 2937.19 or 3504.00) to facilitate fast customs clearance to the US, EU, and Asia.}

^{Analytical Data: Every batch is tested for sequence correctness (MS) and purity (HPLC) to ensure it meets the stringent requirements of transdermal delivery research.}
