Company Introduction

We are a formal and professional manufacturer fully dedicated to the research, development, production and global supply of various peptide raw materials. Having concentrated on peptide manufacturing for years, we have constructed a complete industrial system integrating independent laboratory research, standardized synthesis workshops, full-process quality control and one-stop export service, supplying raw materials for cosmetic, biochemical and formulation enterprises across the globe.
Our factory operates in strict accordance with international industrial norms and standardized production specifications. We own dust-free purified production zones, automated peptide synthesis equipment and professional separation & purification facilities. Every manufacturing procedure, ranging from raw material selection, peptide chain synthesis, chromatographic purification, filtration to sealed packaging and constant-temperature storage, follows unified SOPs. Our product portfolio covers a full range of mainstream peptides such as GHK-Cu, various oligopeptides, small molecule bioactive peptides and custom tailor-made peptides, all maintaining consistent physical and chemical properties among different batches.
Quality assurance stands as our top core operating principle. We set up an independent, fully equipped quality inspection laboratory staffed with professional QC technicians. Each batch of finished peptides undergoes comprehensive item detection, including purity analysis, impurity content test, solubility verification, molecular identification and stability examination. We issue complete COA test reports for all shipments and strictly block unqualified goods from delivery to guarantee reliable raw material supply for our partners.
Besides stable mass production capacity, we also provide flexible customization services to satisfy customers’ unique formula demands. Supported by mature production technology, rigorous quality management and sincere business credibility, we have built long-term cooperative partnerships with clients from numerous countries and regions. We keep optimizing production flows to stabilize product quality and offer responsive pre-sales technical consultation and after-sales tracking service, earning consistent trust and favorable feedback in the global peptide raw material market.

Global Shipping Information

We provide reliable global shipping services covering most countries and regions worldwide to deliver peptide raw materials to every customer smoothly. Our logistics system cooperates with professional international freight forwarders to balance delivery speed and cost, offering stable and predictable transportation arrangements for all orders.
In terms of delivery time, we maintain strict control over the whole shipping cycle. Under normal customs clearance and transportation conditions, the general delivery period will not exceed 20 working days. For many mainstream destinations, the goods can arrive within 7 to 10 days after shipment. The actual transit time is subject to local customs inspection efficiency and regional logistics schedules, yet we consistently optimize transport routes to cut waiting time and shorten overall delivery progress.
As for shipping cost, the unified standard freight charge is 70 US dollars per shipment. This fixed fee covers basic international transportation expenses under regular order specifications, without hidden extra logistics surcharges in most cases. Our team will arrange shipment promptly once payment is confirmed and send tracking numbers to customers for real-time logistics tracking.
We attach great importance to delivery stability to avoid prolonged delays that may affect customers’ production and formulation plans. If any unexpected logistics issues emerge during transit, our after-sales team will actively follow up and communicate with logistics providers to resolve problems efficiently. Our standardized global shipping plan integrates affordable pricing and controllable transit time, bringing convenient and cost-effective logistics support for all global partners.
