Guangzhou Boyuan Outdoor Products Co., Ltd. (hereinafter referred to as "Boyuan") is a specialized biotechnology and chemical trading enterprise based in Guangzhou, China, dedicated to the research, development, sourcing, and global distribution of high-purity peptide products and related biochemical reagents. Originally established with a focus on outdoor equipment and accessories, the company has strategically pivoted and expanded its core business to become a recognized supplier in the competitive peptide market, leveraging Guangzhou's robust logistics infrastructure and its proximity to major chemical and pharmaceutical manufacturing hubs in the Pearl River Delta. Boyuan's peptide product portfolio encompasses a wide array of bioactive peptides, including but not limited to research-grade SM, TR, RT, Selank, Semax, various GHRPs (Growth Hormone-Releasing Peptides) such as GHRP-2, GHRP-6, Ipamorelin, as well as NAD⁺ (Nicotinamide Adenine Dinucleotide), MGF (Mechano Growth Factor), and many other custom peptide sequences. Each product is meticulously manufactured in state-of-the-art, GMP-compliant facilities, and undergoes stringent quality control processes, including High-Performance Liquid Chromatography (HPLC) and Mass Spectrometry (MS) analysis, to ensure purity levels typically exceeding 98% or even 99%, with detailed Certificates of Analysis (CoA) readily available for customer verification. Boyuan offers peptides in various forms to meet diverse application needs, primarily as sterile lyophilized white powders or loose blocks, supplied in standard glass vials with precise dosages ranging from 1mg, 2mg, 5mg, 10mg to custom bulk quantities, all clearly labeled with product name, purity, net content, batch number, storage conditions (typically requiring -20°C or -80°C for long-term preservation), and the corresponding CAS numbers such as 53-84-9 for NAD⁺, 77591-33-4 for TB-500 (if applicable), or sample codes for SM, TR, RT. The company assigns unique model numbers to each specification — for instance, BY-SM-5MG for SM 5mg, BY-TR-10MG for TR 10mg, BY-RT-2MG for RT 2mg, BY-NAD-100MG for NAD⁺ 100mg — ensuring clear traceability and streamlined ordering for research institutions, pharmaceutical companies, and laboratory customers worldwide. Recognizing that peptides are typically intended for in vitro laboratory research, scientific studies, and preclinical development rather than human or veterinary use (unless explicitly authorized), Boyuan strictly adheres to international trade regulations and ethical sourcing guidelines. The company provides professional technical support, stable cold-chain logistics (including freeze packs and vacuum-insulated shipping containers) to maintain product integrity during transit, and responsive after-sales service. With a dedicated quality assurance team, Boyuan can also offer custom synthesis services for rare or modified peptide sequences, providing clients with tailored solutions and flexible lead times. The company's commitment to transparency is reflected in its practice of furnishing complete documentation, including MSDS (Material Safety Data Sheets), COA, HPLC chromatograms, and stability study reports upon request. Over the years, Boyuan has cultivated a reliable distribution network covering North America, Europe, Southeast Asia, and Australia, building long-term partnerships based on consistent product quality, competitive pricing, and professional communication. Despite its origins in outdoor products, Boyuan's successful transformation into a peptide supply specialist demonstrates its agility, technical competence, and customer-centric philosophy. The company continues to invest in refining its quality management systems, expanding its peptide library, and exploring new bioactive molecules to support cutting-edge scientific discovery. For any inquiries regarding pricing, bulk orders, custom synthesis, or technical specifications, Guangzhou Boyuan Outdoor Products Co., Ltd. welcomes clients to initiate direct correspondence through its official sales channels, where a knowledgeable representative will respond with detailed product information, current stock availability, and shipment quotations tailored to specific research requirements. Through unwavering dedication to excellence, Boyuan strives to be a trusted partner in the global peptide supply chain, empowering researchers and developers with premium biochemical tools for tomorrow's breakthroughs.
Epithalon is a synthetic tetrapeptide consisting of four amino acids—alanine, glutamic acid, aspartic acid, and glycine—arranged in the sequence Ala-Glu-Asp-Gly (AEDG) . This compound was developed based on the amino acid composition of Epithalamin, a naturally occurring polypeptide extract derived from the bovine pineal gland . The research program that led to the development of Epithalon was initiated in the 1970s by Professor Vladimir Khavinson at what is now the St. Petersburg Institute of Bioregulation and Gerontology . Over the past 25 years, Epithalon has been extensively studied using in vitro, in vivo, and in silico methods, with research findings documented in numerous peer-reviewed publications . The peptide represents a simplified, synthetic analog of the parent pineal extract, designed for laboratory investigation into fundamental biological processes related to cellular aging, circadian regulation, and tissue maintenance . Each vial contains the precise peptide content verified through high-performance liquid chromatography (HPLC) analysis, presented as a sterile, lyophilized white powder that exhibits excellent solubility in standard laboratory buffers including sterile water and phosphate-buffered saline . The product is manufactured under stringent quality control standards, intended exclusively for research purposes and not approved for human or veterinary use under any regulatory jurisdiction . Safety data indicates that the substance is not classified as hazardous, and standard laboratory handling procedures with appropriate personal protective equipment are sufficient for routine research applications
