We set the Gold Standard because we can back up every result we report.

Every sample is filmed at our Houston lab from the moment the box is opened through its handling in the lab, and the photographs and instrument files are published with the result. Your copy of the unboxing and sample-prep video comes with the video add-on ($49 per sample) or a Gold Standard Membership. We also post our instrument calibration records and the certificates that come with our reference standards, solvents and other consumables. HPLC, LC-MS/MS, ICP-MS, endotoxin and sterility testing for peptides, kratom, supplements, cosmetics, raw materials, water and hydrocarbons.

What we test

Eighteen categories. HPLC, MS, ICP-MS, GC-MS, endotoxin, sterility, pH and more offered across categories.

Door pickup

We send UPS to pick up your samples

Once your order is paid, book a pickup in your client portal and a UPS driver collects the sealed package at your door, with your prepaid label on it. Monday to Friday from the next business day, 9 AM to 5 PM or noon to 5 PM, for a flat fee shown before you pay. Change or cancel free until 8 PM Central the evening before.

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 and tied to its accession number: 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. Your copy of the unboxing and sample-prep video comes with the video add-on ($49 per sample) or a Gold Standard Membership.

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.

    Read the detailsHide the details

    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.

    Read the detailsHide the details

    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.

    Read the detailsHide the details

    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.

HPLC-MS identity and purity is $129 per sample for peptides, SARMs, supplements, cosmetics and raw materials, GLP-1s and blends included, or $199 with net content. Packages take 10% to 25% off the same tests bought one by one, volume discounts start at 10% for 10 samples, and Gold Standard members pay 5% less. The quote in the intake form is the amount charged.

Available payment methods are shown in Stripe at checkout. Invoice at submission; prepaid UPS Ground label available in your client portal.

No. One vial is a normal order.

HPLC-MS identity and purity, $129 per sample for any peptide or blend, GLP-1s included, or $199 with net content (mg per vial). The impurity breakdown is $49 more, and the intake form shows every other test with its price before payment.

One sealed vial as sold, typically 2–10 mg. Endotoxin and sterility each require a separate extra container. Follow the intake form for the total, including any conformity units.

Yes. Identity is confirmed by mass, so we report what is present and at what purity. Each named component in a blend is quantified separately where a reference standard exists.

Every package is opened on camera and each container photographed against the packing list. Containers get an accession number with check digit and a per-vial barcode. Footage is kept three years. Your copy of the unboxing and sample-prep video comes with the video add-on ($49 per sample) or a Gold Standard Membership.

No. The bench copy carries a blind code only.

The retained portion is kept about 90 days for verification and review, then destroyed. During that period we can rerun it, or send it to another laboratory, if a result is disputed.

Enter the accession number on this page or the verify page. A number that does not resolve is not a Gold Standard certificate.

No. Every certificate we sign is published, including failures. Results are immutable once signed; any retraction is logged publicly.

No. Our procedures are modelled on ISO/IEC 17025 with GLP-style data integrity, but we hold no accreditation. SOPs, validation summaries and calibration records are available under NDA.

Each method is verified for the matrix against ICH Q2(R2)-style criteria (specificity, linearity, accuracy, precision, LOD/LOQ) before it is released for reportable use. Our methods are currently in verification. LOD/LOQ is printed on the certificate where it has been established.

Raw files are archived unaltered, and each certificate is hash-signed. Records are electronic, audit-trailed and tamper-evident. Raw data published on opt-in.

Yes. Qualifying accounts can tour the lab and review SOPs, method references and calibration records under NDA. The instrument registry is public on the quality records page.

It comes off client work until re-qualified, and the service record says so.

Order first. Your prepaid UPS Ground label is provided at submission. Ship in a padded mailer; supply links are on the intake page. No walk-in drop-off.

We hold no DEA registration, so we cannot receive Schedule I–V material. Cold-chain samples should ship on ice packs early in the week.

The certificate states which analyte was out of specification and by how much. It is published like any other result. You may request the retained sample for retest within 90 days.
