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. 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 83% across 5 tests (read 20 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.
