Prodigypeptides (prodigypeptides.com) caught my eye on price, so I'm poking around before I do anything. Couple things I want to nail down. Are the COAs tied to actual lot/batch numbers, and do they show the third-party lab's name, the analytical method, and the test date?
Does the catalog list purity/identity specs for each product or just names and sizes, and are the current prices per vial/unit — any minimums or bulk tiers? Shipping: where do they ship from, domestic vs international options, which carriers, packaging, tracking, stated transit times?
Also, is there a published business location or jurisdiction, and a contact/response policy if I want docs before buying? And how are COAs updated when lots change — can I request one for the exact lot before ordering?
