Peptidescores keeps popping up when I compare shops. Before I even think about a catalog item, I want the stuff I can’t ever find in public listings. Does the product catalog show exact vial sizes, purity specs, and batch/lot identifiers for each peptide?
Are the COAs current, third-party, and searchable by batch, with HPLC/MS methods and results included? What are the published shipping terms—origin location, carriers, packaging, transit times, tracking, and any temperature-control options?
Are listed prices inclusive of shipping, taxes, or duties, and do they change by quantity or destination?
And how can buyers verify the vendor’s business location and quality-control practices before ordering? If anyone has actually dug into them, I’d rather hear that than another generic “looks good.”
