Raw material sourcing
We source from qualified peptide manufacturers and synthesis labs, not repackagers.
We hope every product satisfies you and meets your expectations. Our products are manufactured and sold strictly for laboratory and research use, and are not intended for human or veterinary use.

WL Health is a comprehensive high-tech enterprise integrating the R&D, production, and sales of high-purity bioactive peptides. We operate independent laboratories and standardized, sterile production facilities. Our products undergo rigorous testing—including HPLC analysis and checks for microorganisms and heavy metals—ensuring compliance with standards for cosmetics, health supplements, and laboratory research.
We have always been dedicated to helping users on their journey toward weight loss and better health.
Upholding a spirit of professionalism, dedication, and integrity, we specialize in direct manufacturer supply, small-batch custom production, and peptide synthesis services. Our peptides achieve a purity of ≥99%, and we provide comprehensive COA reports to facilitate smooth customs clearance for users and buyers.

Every compound is characterized before it ships. We test identity and purity by HPLC and mass spectrometry, and issue a batch-specific Certificate of Analysis you can download.
We source from qualified peptide manufacturers and synthesis labs, not repackagers.
A third-party lab verifies purity by high-performance liquid chromatography, with a minimum threshold of 99%.
Mass spectrometry confirms the peptide’s molecular identity matches what’s on the label.
Every batch ships with a COA you can view on the product page or request by lot number.
We are a team of researchers and technicians who believe research-grade material should come with research-grade documentation. Questions about a batch, a COA, or an order? We reply within 24 hours, Monday–Friday.
