Peptide Researches is on my shortlist while I'm comparing shops, but I want to nail down a few things before any lab purchase. What are the eight products currently in the catalog, and do the listings stay updated with batch numbers and sizes?
Are published prices per vial/unit, and do they include domestic US shipping? If so, what carriers, timelines, and packing details? Can I get batch-specific COAs before ordering, and which third-party lab and methods (HPLC, MS, etc.) are shown?
Public listings note COA verification by only one reviewer — can the vendor share full current COAs and verification records? Where in the US are they based, and do they ship only domestically or also internationally for research use? Any firsthand info appreciated.
