Ion sells semaglutide as ION-1S, tirzepatide as ION-2T and retatrutide as ION-3R. That mapping is confirmed to us first-hand rather than read off a certificate.
Ion Peptide publishes a searchable Certificate of Analysis library, with separate endotoxin reports for many lots, at ionpeptide.com/lab-results. This page previously gave its size as roughly 195 entries; that figure has been withdrawn, because it was inherited from an import rather than counted, and the identical number turned out to be wrong on another vendor’s page. The library is real — only the number is gone. The certificate we reviewed — a 5-Amino-1MQ batch, report KVR-2026-BA8308 — was issued by Kovera Labs and is unusually complete: batch-average purity of 99.887% by RP-HPLC (C18 column, DAD detection at 214 nm), identity confirmation by LC-MS, net-content assay, an endotoxin safety screen (≤0.5 EU/mL, passed), a microbial sterility screen (no growth), four-analyte heavy-metal screening (arsenic, cadmium, lead, mercury — all negative), and per-vial batch-conformity results across three vials. It is signed by the lab’s director and carries a QR code and per-record access code that resolve to the laboratory’s own verification page at koveralabs.com/verify — the check runs against Kovera, not against Ion. Kovera Labs is the same independent laboratory behind several other vendors we cover.
Two points of context. Kovera Labs does not print an ISO 17025 or A2LA accreditation on its certificates, so no accreditation is claimed here — the strength of the report is its panel breadth and the independent, externally verifiable check, not a printed accreditation. And the certificate we read in full is a single lot of one compound; the library itself is broad and per-lot, but a researcher should confirm the specific batch on hand at koveralabs.com/verify before use.
On 27 September 2026 Ion’s own site-wide banner listed three savings it presents together: 30% off sitewide, the addition of an affiliate code on top of that, and 5% off for paying by ACH at checkout. Ion describes the whole set as part of a named, limited-time promotion — its banner reads “Limited-time offer” and refers to the sale ending — but publishes no end date, so none is given here and none should be inferred. The ACH discount is read from that same promotional banner rather than from a standing payments or terms page, so whether it outlasts the promotion is not something Prof. Peptide can state. Prof. Peptide has not tested whether these combine with the discount code above; Ion’s banner says an affiliate code adds to the sitewide figure, which is Ion’s claim rather than a Prof. Peptide measurement. Ion’s product pages separately list quantity pricing — 10% off 4–5 units, 16% off 6–9, and 25% off 10 or more — checked 28 September 2026 on the ION-1S and TB-500 product pages, where the percentages matched. Ion does not state whether the PROFPEPTIDE code combines with this quantity pricing either.
Finnrick rates Ion Peptide 82% across 4 tests (read 30 September 2026) — a pass rate across those tests, weighted so that newer tests count for more, not a purity figure.
