Seller table
Peptide sellers compared: who shows their lab reports
Ten US peptide sellers, checked one by one on what their own websites actually show: a named testing lab, viewable batch reports, public prices. Every cell says the day we looked and links the page we looked at.
Byline: Mark Sommers, editor. Full table check 08-24-2026; rows re-checked since then carry their own date. Scoring rule below the table. Not buying advice; see how we rank.
How to read this: the score only measures what you can verify in a browser before you pay. A high score means the paperwork is easy to check. It does not mean the product is good, and a low score is not an accusation; it means we could not find the thing on the seller's own pages that day.

The scoring rule
Lab named on a readable page: 3 points. Per-batch lab report viewable without asking: 3 (2 if it is an image instead of a PDF). A dedicated report hub or index: 2. Prices public before checkout: 1. A third-party review profile: 1. Ten points possible. Ties sort alphabetically. The rule was published on our methods page before this table existed, and the Formula number on every row is what it produces.
Think a cell is wrong?
Sellers change their pages, and we can miss things. If you run a seller on this list and a cell is out of date, tell us which cell and link the page that shows it. We re-check against your link, fix the cell, and update the checked date. Same deal for readers. What we will not do: change a cell based on a claim with no page behind it.
What changed since our first pass
Four of these sites blocked our automated check on 08-22-2026, so their cells said "not shown." All four were readable on 08-24-2026 and their cells are now filled from their live pages. That cut both ways: one blocked seller turned out to name its lab and run a searchable report library, and another turned out to have no viewable reports at all.
