Guangzhou Weitai Biotechnology Co., Ltd. — a factory-source peptide manufacturer trusted by research teams, clinics and distributors in 40+ countries.
VTA Biotech is the international brand of Guangzhou Weitai Biotechnology Co., Ltd., headquartered in the Baiyun District of Guangzhou, China. Unlike trading companies, we own the entire production chain — solid-phase peptide synthesis, purification, lyophilization, analytical QC and cold-chain packing all happen inside our own facility.
Our catalog covers 67+ compounds across eight categories, from GLP-1 metabolic peptides to cosmetic copper peptides, all manufactured at ≥99+% purity. We serve individual researchers, clinics, aesthetic studios and large distributors — and we welcome custom synthesis and OEM production at any scale.
