Company Overview
LIANTAO Peptide operates as a peptide manufacturer founded in 2014, offering custom synthesis and catalog products produced via solid-phase peptide synthesis. The company targets brands, laboratories, formulators, and distributors across more than 40 countries. Its website publishes product catalogs spanning cosmetic, research, and nutritional peptides, alongside company history, regulatory compliance information, and blog articles on peptide analysis.
Every shipment includes documentation such as Certificates of Analysis (COAs), Material Safety Data Sheets (MSDS), and HPLC/mass spectrometry data upon request. The site lacks an online checkout system, requiring buyers to submit inquiries for personalized quotations, samples, lead times, and variable minimum order quantities. Orders are shipped internationally from China using express couriers with temperature-controlled packaging, while buyers remain responsible for local import duties and permits.
Pros
- Offers full technical documentation including COAs, MSDS, and HPLC/mass spectrometry data.
- Maintains a catalog of over 500 peptide products with custom synthesis capabilities from milligram to kilogram scale.
- Provides sample availability and batch traceability for quality evaluation.
Considerations
- No public pricing or online checkout available on the website.
- Minimum order quantities vary by product and require direct inquiry.
- Import duties, local taxes, and clearance fees are the responsibility of the buyer.
