Read on 6 September 2026 on the vendor's own pages and the independent platforms linked. These are the findings behind the 8/10 above — not a summary of the vendor's marketing.
The review record is real and large. The documentation behind it is not: the page that names the lab was lifted from another vendor's website, the certificates use a different lab's coding, and the company is named three different ways. 313 happy customers is meaningful; it is not the same thing as knowing who tested the vial.

Each row is a certificate we opened and read ourselves; "verify at the lab" goes to the laboratory's own lookup, never a copy we host. Full COA library →
Every re-verification is dated and kept; a score only changes when the evidence does.
Smaller independent review base than several competitors (80 reviews). The catalog is peptide-focused, so researchers also working with SARMs or broader research chemicals will need a second supplier.
The FAQ that names Freedom Diagnostics is copied from an unrelated vendor's site, complete with links to that vendor's account pages — and the certificate filenames carry a different lab's code. The standalone BPC-157 page, About and Team pages are behind a registration wall. Three different company names and three addresses across Contact, Terms and Refund pages. Sells HCG and HMG. GLP products sold as ION-1S / ION-2T / ION-3R with no stated identity.
Context from our hand-written research that the numbers above cannot carry — brand confusion, catalog risk, testing specifics. Nothing here changes the score.
Check the domain carefully. The substantial review record belongs to ionpeptide.com — singular. A separate ionpeptides.com - plural - holds a 3.2 rating from one review, and we could not establish any relationship between them. One letter separates a substantial track record from essentially none.
Purgo Labs, on the evidence: 10/10 rubric points against 8/10. Ion Peptide is stronger on 4 points listed below. Every point is a fact you can check on either vendor's site; both are scored by the same published rubric.
Ion Peptide scores 8/10 on our rubric, has an independently viewable rating of 4.7 (420 reviews), and names its lab (Kovera Labs (on certificates) · FAQ claims Freedom Diagnostics). Caveat: The FAQ that names Freedom Diagnostics is copied from an unrelated vendor's site, complete with links to that vendor's account pages — and the certificate filenames carry a different lab's code. The standalone BPC-157 page, About and Team pages are behind a registration wall. Three different company names and three addresses across Contact, Terms and Refund pages. Sells HCG and HMG. GLP products sold as ION-1S / ION-2T / ION-3R with no stated identity.
On the 1 compound-and-size rows where we have dated prices from both, Ion Peptide lists lower on 1 and Purgo Labs on 0. Purgo's list prices drop 20% with code HEALTH.
