Peptide Deck is a US-based vendor that sells both retail and bulk peptides, with a moderate catalogue and prices listed on around three-fifths of their products. Testing coverage is minimal—one COA on file from an Australian lab showing 98% purity by HPLC. Early community mentions lean positive on product quality and testing transparency, though the sample is thin: just a few mentions from a single source.
