CURATED VENDOR PROFILE
Ion Peptides
Included because it now has a clearer U.S. footprint, visible COA navigation, and a public quality-assurance layer that is stronger than a bare storefront.
REFERRAL OFFER
15% off with disclosed code
Code benchmark takes 15% off. At checkout it applies after Ion’s per-product quantity discount or its sitewide sale, whichever is cheaper for that product, and the pricing board and Stack Builder combine them the same way.
PeptideBenchmark has a disclosed affiliate relationship with Ion Peptides. This does not change benchmark scores or trust ratings — it only affects outbound links and pricing-board discount modeling where applicable.

The lab-results layer turns out to be substantial: a public /lab-results/ library maps most of the catalog to per-batch third-party reports — Freedom Diagnostics and Kovera Labs — and nearly every one can be confirmed at the issuing lab, with a set of products also carrying separate endotoxin reports.
Readers who want a wide catalog where nearly every batch is backed by a third-party lab report — Freedom or Kovera — that they can verify at the lab’s own site.
Some report images do not expose an easily readable purity value. Use the per-batch Freedom or Kovera verification link to confirm the original lab report.
Third-party Freedom Diagnostics + Kovera Labs COAs with public provider verification
Ion’s public /lab-results/ library lists per-batch reports across 92 products, and the large majority can be checked at the lab rather than taken on the vendor’s word: Kovera Labs reports resolve by their KVR code on Kovera’s public lookup, and Freedom Diagnostics reports by their accession on Freedom’s public COA search. A subset of products publish separate Freedom endotoxin reports on top of purity. That is broad, provider-verifiable public evidence rather than the performative lab page it first appeared to be.

Assayed content is not fill accuracy. Laboratories report net peptide content, and peptides ship as salts, so an honestly filled vial commonly assays below its gross label — a figure under 100% is not evidence of a short vial. These numbers are also not comparable between vendors: they exist only where a laboratory reports net content, so they partly reflect which laboratory a vendor uses.
