Independent verification.
Public verification.
We don’t sell what we test.
Gold Standard has no vendor relationships, no ownership stake in any brand we test, no skin in the game beyond the accuracy of the result. Our clients are the brands whose customers demand proof — not distributors who benefit from us looking the other way.
Every COA is publicly verifiable.
Every public COA we issue carries a unique accession number searchable at goldstandardanalytics.com/coa-lookup. Customers can confirm a result in real time — not just take a vendor's word for it.
What the instruments actually see.
Current-generation analytical instrumentation calibrated weekly against traceable reference standards. Every instrument is validated before use and subject to per-batch system-suitability verification. Select any platform to see exactly what it measures and which panels run on it.
- Purity % and impurity profile by peak area
- Label-claim potency vs. stated dose
- Net peptide content (with amino-acid-analysis anchor)
- Cannabinoid / alkaloid profiles (16-cannabinoid, mitragynine, 7-OH)
- Identity confirmation by exact mass (m/z) — the assay HPLC alone can't do
- PFAS at parts-per-trillion (EPA 533 / 537.1 / 1633)
- 60-analyte pesticide multi-residue panel + glyphosate / AMPA
- Mycotoxins, vet drugs, undeclared actives
- USP <232>/<233> elemental impurities (Pb, As, Cd, Hg + full panel)
- EPA 200.8 drinking-water metals (Lead & Copper Rule)
- FDA Closer-to-Zero metals for baby food / juice
- Trace contamination to parts-per-trillion
- Bacterial endotoxin (EU/mL) in anything injectable-adjacent
- Kinetic chromogenic quantitation, not just pass/fail
- Injectable-grade safety alongside sterility + metals
- TFA vs. acetate counter-ion identity and residual %
- Anion screen: sulfate, chloride, fluoride
- Free HF in battery electrolyte
- Water % in lyophilized peptide cakes
- Moisture in raw materials, powders, food matrices
- Feeds net-peptide-content math (mass balance)
- Accelerated aging (ICH-style 40°C / 75% RH) with assay at pull points
- Photostability and freeze–thaw stress for emulsions
- Preservative efficacy over shelf life (with USP <51>)
- Total aerobic count / yeast & mold (USP <61>)
- Specified organisms — E. coli, Salmonella, S. aureus (USP <62>)
- Sterility for injectable-grade panels (USP <71>)

A real lab, at a real address.
Plenty of testing outfits are a P.O. box in front of a broker. We're the opposite: one Houston facility where your sample is received, logged on camera, run, and signed out. Come see it.
Houston, TX
5709 Gardendale Dr STE D

Ship all samples to this address using the prepaid waybill we email after submission. Visits are by appointment — book a lab tour below or email ahead so an escort is ready at intake.
What you'll see on site
- Camera-monitored intake & chain-of-custody station
- The Agilent HPLC / LC-MS/MS / ICP-MS bench
- Endotoxin (LAL) and Karl Fischer stations
- Reference-standard library & calibration logs
- How a COA gets reviewed, signed, and published
Our clients get the full tour.
Transparency shouldn't stop at the COA. All of our loyal customers with an established business relationship — anyone who's run testing with us — are welcome to a private tour of the Houston lab: walk the bench, meet the analysts, and watch your own sample class move from intake to sign-out. Sign in and the scheduler below goes live.
Walk the bench your samples run on.
Lab tours are open to all of our loyal customers with an established business relationship — anyone who's completed testing with us. Book a private 45-minute tour of the Houston lab: intake, chain-of-custody, the HPLC / LC-MS/MS / ICP-MS bench, and how a COA gets signed out. Bring up to 5 colleagues.
Ten commitments.
Where we sit among the testing labs.
The research-compound community already trusts a handful of independent labs. Here is an honest, side-by-side look at how Gold Standard lines up against them — accreditation, the instrument methods on the bench, whether an injectable-grade safety panel is even offered, public COA verification, pricing transparency, and turnaround. We compete on doing all of it in one place, with published prices and a public COA on every job.

Snapshot compiled Q2 2026 from each lab's own public pages and community COA databases. Competitor capabilities, accreditation scopes, and prices change without notice — confirm current terms with each lab directly. Listed labs are independent third parties; Gold Standard is the only one that pairs a fully published, per-panel price list with a no-login public COA on every job and an in-house HPLC + LC-MS/MS + ICP-MS + LAL stack under one workflow.
