Testing: Labs & Certificates of Analysis
Ion Peptide publishes a lab-results library organized by product and dose, where Prof. Peptide counted 121 products and 674 lot certificate links on 8 October 2026, with the current lot of each product marked. Ion Peptide states that it verifies every batch of every product through independent third-party laboratories, and that every peptide is synthesized to 99%+ purity.
Certificates from two of the library's laboratories were checked at each laboratory's own lookup on 8 October 2026: Freedom Diagnostics and Kovera Labs. Each named Ion Peptide as the client and matched the vendor's copy, and each lookup refused an invented code first, so a match means something. Freedom's reports cover purity, net content and identity by HPLC with mass spectrometry, and some lots carry a separate endotoxin report; Kovera's cover purity, net content, identity by LC-MS, endotoxin, sterility and a heavy-metal screen.
Ion Peptide also states that a customer who has a product HPLC-tested at one of the approved laboratories listed on its rebate page may receive a 100% store-credit rebate covering the test and the product, when every condition is met.
Finnrick rates Ion Peptide 82% across 4 tests (read 8 October 2026) — a pass rate across those tests, weighted so that newer tests count for more, not a purity figure.
All products are sold for laboratory research use only.
