Quality Assurance

Research-grade peptides with verified purity

Peptide Plus supplies laboratory researchers with high-purity peptides for in-vitro and pre-clinical work. Every lot ships with a batch-specific Certificate of Analysis (COA) issued by an independent testing laboratory, with HPLC and mass spectrometry data on the document.

From individual peptides like BPC-157 and TB-500 to Khavinson peptide complexes, our catalog is designed for scientific research institutions and qualified laboratories — not for personal, clinical, or supplemental use.

All products are intended for laboratory research use only. Not for human consumption, veterinary use, food, drug, diagnostic, therapeutic, or cosmetic applications.
