Peptide vendors in the price index

Each vendor page carries the same set of figures: every tracked listing with its price per mg, how those prices sit against the median for the same peptide and vial size, a COA coverage rating for the in-stock products we track, a 90-day price history, and the shipping, payment and coupon facts we have recorded from the vendor's own site. The numbers are observations we collect, not quality ratings; coverage reflects the certificates our crawler found, vendors may publish more than we index, we do not test products and no vendor is endorsed.
