Received my order in 3 days. The COA matched the product exactly and the peptide performed as expected in my assays.

Reliable vendor

Third order from them. Consistent quality across batches. Customer service is responsive to any questions about documentation.

Good quality, decent price

Verified

Purity was verified by independent HPLC. Slightly pricey compared to alternatives but the documentation quality justifies it.
