Yiwu Huangxin Trading Co., Ltd. is a premier global supplier and exporter specializing in the research, development, and distribution of premium peptide products. Strategically located in Yiwu, Zhejiang Province—the world's largest capital of small commodity trade—our company leverages an unparalleled geographical advantage and a robust logistical network to serve clients across the globe. Since our inception, we have dedicated ourselves to bridging the gap between cutting-edge biotechnology and commercial accessibility. We operate on a foundational business philosophy: providing the highest purity products at the most competitive wholesale prices, ensuring our global partners achieve maximum market advantages.

Over the years, Yiwu Huangxin Trading Co., Ltd. has evolved from a regional trade entity into an international enterprise. We maintain strategic alliances with top-tier domestic manufacturing plants and bio-laboratories. This integration allows us to oversee every step of the lifecycle, from raw material procurement to ultimate international delivery. We firmly believe that the future of wellness, cosmetics, and pharmaceuticals lies in molecular science. By focusing heavily on the peptide sector, we have established ourselves as a reliable node in the international supply chain. We consistently deliver excellence without compromise.

In the highly demanding market of biochemical products, two variables dictate success: purity and cost-effectiveness. At Yiwu Huangxin Trading Co., Ltd., we have harmonized these two aspects to create an unbeatable value proposition. Our peptide portfolio boasts a standard purity level of 98% and above, with many of our flagship customized peptides reaching up to 99.5% purity. This exceptional level of refinement is achieved through state-of-the-art purification techniques, including advanced High-Performance Liquid Chromatography (HPLC) and Mass Spectrometry (MS). By ensuring ultra-low impurity profiles, our peptides deliver superior stability, bio-activity, and safety in final formulations.

While high purity often commands a premium price in the western markets, Yiwu Huangxin Trading Co., Ltd. disrupts this convention by offering exceptionally low prices. We achieve this through massive economies of scale, long-term raw material contracts, and highly optimized automated production processes at our partnered facilities. Furthermore, being headquartered in Yiwu allows us to dramatically lower our operational, warehousing, and shipping overheads compared to companies based in hyper-expensive industrial zones. We pass these substantial savings directly down to our buyers, offering factory-direct pricing structures that allow distributors and end-manufacturers to double their profit margins

Pharmaceutical & Research Peptides: For laboratories, universities, and pharmaceutical developers, we offer high-grade research peptides synthesized under strict sterile conditions. Our fast-turnaround custom peptide synthesis service can replicate complex sequences according to exact molecular specifications.
Nutritional & Health Peptides: We provide bulk dietary peptide powders, including Marine Collagen Peptides, Soy Peptides, and Pea Peptides. These possess excellent solubility and high absorption rates, perfect for health supplements and functional food industries.

Research

Class:

Actin-sequestering protein / 43-amino-acid peptide

Status:

Research compound — Not FDA approved (investigational: RGN-259 for dry eye / neurotrophic keratitis)

Mechanism:

A naturally occurring 43-amino-acid peptide (Ac-Ser-Asp-Lys-Pro-Asp-Met-Ala-Glu-Ile-Glu-Lys-Phe-Asp-Lys-Ser-Lys-Leu-Lys-Lys-Thr-Glu-Thr-Gln-Glu-Lys-Asn-Pro-Leu-Pro-Ser-Lys-Glu-Thr-Ile-Glu-Gln-Glu-Lys-Gln-Ala-Gly-Glu-Ser-OH) that binds G-actin (sequesters monomeric actin), preventing F-actin polymerization. Promotes cell migration, angiogenesis, wound healing, and anti-inflammatory responses via integrin-linked kinase (ILK) and HIF-1α/VEGF pathways. TB-500 is the synthetic fragment Ac-LKKTETQ (MW ~895) often sold under this CAS.

Activity note:

Thymosin Beta-4 is an actin-binding protein, not a receptor agonist. Functional activity is measured by actin sequestration (Kd ~0.7–1 μM) and cell migration assays, not EC₅₀.
