ILS Lab
San Diego analytical laboratory with a dedicated peptide-testing page and a working public COA verification portal: each certificate carries an access code that resolves the full report at ils-lab.com.

Open review queue →This label reflects how the provider presents itself on its own site today, not a formal accreditation category.
Whether the site appears to invite direct sample submission from individuals rather than only business or institutional clients.
Whether the provider appears to offer public-facing report publishing, result browsing, or direct verification tooling.
This is our shorthand for how visible the provider's result or verification layer appears to be, ranging from none to searchable public verification.
Location details are kept conservative and only shown when clearly supported by the source page or the provider’s public materials.
What we can verify now
ILS Lab runs a genuine public COA verification portal, which we confirmed directly rather than inferring from marketing language.
Every ILS certificate prints, in its header, a COA number, an access code, and a “Scan to verify authenticity” prompt. Entering that access code at ils-lab.com/verify resolves to the full, lab-hosted certificate — product, lot, purity, and the pass/fail panel results — under an explicit “Verified and authentic” banner.
We checked that this is real, not decorative: valid access codes from live vendor COAs resolve to their matching certificates, while a fabricated code is rejected with “Unable to verify this code.” That is the behavior of a real verification system.
The lab itself is in San Diego, California (per the address and area code printed on its certificates), and reports a Full QC Panel covering purity (HPLC-UV), identity, endotoxin, sterility, and heavy metals, plus a fentanyl screen.
Why it matters in the current ecosystem
ILS sits in the strongest evidence tier, alongside providers like Freedom Diagnostics: a reader holding a vendor’s COA can independently confirm it against the lab’s own site, without trusting the vendor’s copy of the document. That makes any vendor whose COAs carry a resolvable ILS access code meaningfully more verifiable than one hosting only a static PDF or image.
What to watch for
Verification is per-certificate: it confirms the specific batch on the COA, not the vendor’s whole catalog. Direct-consumer sample submission is not confirmed here (intake looks business/institutional), so treat ILS as a testing lab whose certificates you can verify, not necessarily a service you would submit your own sample to.
