BioTech Peptides

Established US-domestic peptide synthesizer with a substantial catalog and same-day shipping. It does publish per-batch COAs - 84 of 89 product pages carry a downloadable certificate, most of them MZ Biolabs reports naming the client and lot, with a set of older SKUs on a lab-unnamed template. Public-data audit; we have placed no test order.
