The certificate links all lead to a single page on Peak Lab Peptides' site; the report for your lot should be listed there. Peak Lab Peptides says testing is done by an independent lab. Its stated delivery terms: same-day processing before 6 PM ET; 1–5 business days delivery; UPS Ground, 3-Day Select, 2nd-Day Air, and Next Day Air available. You can pay with credit or debit cards, Zelle, Apple Pay and Google Pay. Alongside single vials it lists 6 bundled kits. Most of its listings are for Retatrutide, NAD+, BPC-157, GHK-Cu and MOTS-c. Some products come in several strengths; Retatrutide, for example, is sold in five. Any order is placed with Peak Lab Peptides directly, never with PepLookup, and the products are for research use only.
