What we test
Eighteen categories. HPLC, MS, ICP-MS, GC-MS, endotoxin, sterility, pH and more offered across categories.
Product and environmental testing
Methods cited on every certificateIdentity, purity and net peptide content for GLP-1 class, blends and sterility and endotoxin panels.
Potency, identity and analog screen for capsules, liquids and powders, measured against the label claim.
Mitragynine and 7-OH quantification, heavy metals, microbial limits and pesticide residue.
Label-claim verification, vitamin and mineral potency, heavy metals and undeclared ingredients.
Active potency, preservative efficacy, heavy metals and microbial limits for serums, creams and topicals.
TPH by carbon range, BTEX and the 16 EPA priority PAHs in soil, water, fuels and used oil.
Multi-residue panel plus glyphosate and AMPA in produce, botanicals, soil and water samples.
PFAS, metals under the Lead and Copper Rule, Closer to Zero panels and mycotoxins.
Lab equipment and consumables marketplace
Lower fees, and listings built to be found by labs searching for equipment. Buy used equipment, sell or trade in yours, or consign it with us. Every lot is photographed as it ships and says what has not been verified.
Chain of custody
Most laboratories ask you to trust the certificate. We publish the evidence behind it. From the moment your package is opened at our Houston lab to the signed certificate, every stage of your sample’s handling is recorded, tied to its accession number, and available to you: the unboxing video, a photograph of each container, the calibration status of the instrument it ran on, the raw data files, and the analyst who signed. When an approved partner lab runs a test, the hand-off is recorded and the certificate names that lab.
Receiving
Your carrier tracking number is matched to your order at the desk. The sealed package is weighed and photographed before anyone opens it, so the record starts before we touch the contents.

Certificate integrity
Three safeguards keep each certificate tied to the sample we tested and the client we issued it to.
Proof that the sample belongs to the certificate
Filmed receipt, container photos and blind codes connect the tested sample to its accession and analytical record.

Every package is opened on camera, each container is photographed and blind-coded before the bench sees it, and the footage, photos, instrument ID and raw data are linked to the accession. Anyone holding the certificate can trace it back to the vial that was tested.
Watermarked and branded to the client
Client branding, the lot, a document hash and a verification QR code keep the certificate tied to its source.

Certificates issued to a brand carry the client’s logo and name as a watermark, alongside the accession, the lot, the SHA-256 hash and a QR code to the live record. A certificate for one client cannot be passed off as another’s, and one lot’s result cannot be reused for the next.
A legal team that pursues misuse
Public verification exposes altered certificates. Report suspected misuse so our team can investigate and act.

Fake and altered certificates are the largest problem in third-party testing: a real lab’s name on a document the lab never issued. Because every Gold Standard record is public and hash-bound, a forged or edited PDF fails verification on the spot, which removes most of that risk before anyone has to act. Our counsel acts on every fake or altered certificate and every unlicensed use of the Gold Standard name or mark: takedown notices to marketplaces and registries, notice to payment processors, public misuse notices on the record, and claims under the Lanham Act and the Texas Deceptive Trade Practices Act. Vendors who test with us are protected by it; those who counterfeit it are not.
Report a certificate that does not verify, or suspected misuse of our mark, to team@goldstandardanalytics.com.
If you think we got it wrong
Laboratory measurement has real uncertainty, and different labs, vials or methods can legitimately disagree. If you believe a result is wrong, tell us while we still hold your retained sample, which we keep for about 90 days.
We don’t refund because a result is unwelcome or differs from another lab’s. Orders placed before September 23, 2026 keep the guarantee they were sold with. How refunds work.
What we do
- Analytical review
We re-check the raw data and calculations, and can rerun the retained material, use a second method or send it to another laboratory.
- Public correction
If we made a material error, we correct or retract the certificate publicly, on the same accession.
- Credit or refund
If an error of ours can’t be fixed by correcting or rerunning the test, we credit or refund that test.
See the refund policy for the remedies that apply to your order.
