Discover the leading Chinese peptide company dedicated to synthesizing high-purity research grade raw powders for laboratories and cosmetic brands worldwide.
COSPEP Biotech was founded with a singular vision: to bridge the gap between high-scale manufacturing and the meticulous purity standards demanded by global chemical research. Operating out of our ISO 9001 and GMP-compliant industrial facility in Shaanxi, China, we have grown into one of the most reputable peptide manufacturers in China.
We focus exclusively on active cosmetics ingredients and biochemical research peptides, including Tirzepatide, Retatrutide, and high-demand recovery peptides like BPC-157. Our core team consists of Ph.D. chemists and biochemists who oversee every synthesis cycle from molecular docking to crystallization.
Equipped with solid-phase and liquid-phase peptide synthesizers, capable of preparing custom peptide sequences from milligram pilot runs to multi-kilogram commercial batches.
We employ prep-HPLC systems and freeze-drying technology to ensure that residual solvents, TFA salts, and moisture content are kept to a strict minimum.
Equipped with advanced LC-MS spectrometers, Karl Fischer titrators, and gas chromatographs. No batch leaves our factory without a comprehensive COA and HPLC trace.
