Planning an order soon, so I've been poking around Veltrix Peptides (veltrixpeptides.com). Their public listings show 10 products, prices out in the open, shipping info, COA documents, and a China location.
Before I send anything: for those 10 products, are the COAs lot-specific and can I see them before buying? Do they actually show third-party HPLC/MS purity, assay, and testing dates?
Who's the lab issuing them, and can I verify the batch numbers with that lab directly? Also wondering whether the published prices include shipping or if there's separate cold-chain, customs, and reshipment stuff on China-origin
