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. Nobody paid to be here and nobody can pay to move up.
Byline: PeptideGauge Editors. All cells checked 2026-08-24. 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, so it cannot be bent to fit a result.
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 If you run a seller on this list and a cell is out of date, tell us which cell and link the page that shows it.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, update the checked date, and log the change on the fixes list. 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 2026-08-22, so their cells said "not shown." All four were readable on 2026-08-24 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.
