Peaklife Extension supplies high-purity research peptides from the European Union. Every batch is independently tested at Janoshik Analytical for amount, HPLC purity (>99%), sterility, endotoxin and heavy metals.
We publish batch-specific Certificates of Analysis so researchers can verify exactly what they receive. Orders are packed and dispatched from the EU.
All products are laboratory reagents. They are not medicines, foods, supplements or cosmetics, and they are not for human or animal use.
