HPLC + MS as the standard pairing on every peptide, botanical, supplement, and cosmetic identity panel — quantitation by HPLC, identity by MS. Environmental matrices use method-appropriate chemistry (LC-MS/MS, ICP-MS) published with the EPA reference number on every COA.
Gold Standard Analytics is an independent third-party analytical testing laboratory in Houston, TX — operated to ISO/IEC 17025 expectations with GLP-style data integrity, weekly traceable calibration, and full video / photo chain of custody on every sample.
We don't sell what we test. No vendor relationships, no ownership stake in any brand — our only product is the accuracy of the result, and every public COA we sign is verifiable by anyone, no login required.
Most “certificates of analysis” circulating today were produced by the same vendor selling the product. Quality across that population is uneven, and category-wide industry surveillance has documented recycled lots and fabricated documents. The only structural cure is a lab with no stake in the outcome.
Authenticity isn't a promise on a PDF; it's a chain you can follow from the moment your package is opened to the second anyone verifies the COA. Walk the exact path every sample takes — it runs on its own, or click any step.
Every inbound package is unboxed on camera the moment it arrives. Nothing is prepped, split, or logged off-screen — the footage is retained for 90 days and available to the client of record on request.
Video intake · 90-day retentionThe fastest way to know a result is real is to make the path from sample to signature unambiguous. We document every step on video, publish the raw instrument files when the client opts in, and calibrate our primary instruments on a weekly schedule with system-suitability checks before every run.
You need a COA on every lot. We issue one — publicly verifiable, QR-enabled, with a widget your product page can embed so customers can re-check the current batch themselves.
Use our lookup tool as a buyer-safety gate. Any brand you stock should be able to produce a Gold Standard accession number; if they can’t, you have a policy question to ask.
For peptides, reference materials, and botanicals purchased for research use, we confirm identity, purity, and endotoxin before the vial goes on the bench.
ISO/IEC 17025-aligned SOPs, video / photo chain of custody, retained samples. Our documentation packages support FDA inspection responses, NSF audit packets, retailer onboarding, and the analytical portion of USDA organic recordkeeping (we are not a USDA organic certifier).
Found a COA number on a bottle? Search it here. We’ll show you whether it’s real, whether it matches the product on the shelf, and the date it was signed.
Investigating a product class? We publish industry surveillance findings and can run blind-sample panels on request for documented editorial or regulatory work.
Under 2 minutes. Product type, compound, lot, and test panel. Upload an existing spec sheet if you have one and we’ll match the target specs.
An invoice is issued the moment you submit. Once payment lands, we automatically generate and email a pre-filled UPS waybill (Ground standard, Next Day Air rush) with cold-pack requirements where applicable. Drop the package at any UPS location.
HPLC + MS as the standard pairing for product panels (peptide, botanical, supplement, cosmetic, raw API). Environmental matrices use the EPA reference method appropriate to the analyte. Add ICP-MS, LAL, microbial, residual solvents, or PET as the panel requires. Live status in your portal.
Published to the verification portal. Download the PDF, copy the accession number, or embed the QR widget on your product page.
A peak at 5.2 minutes. m/z 4113.58 ± 0.02. Your COA isn’t a summary — it’s a receipt from the instrument itself, on our Agilent 1290 III HPLC, Agilent mass spec, Agilent ICP, and Charles River Endosafe stack.
Every peptide base price includes Identity + Purity + Net Content on one public COA, in three tiers — Standard $189, Complex / Large $239, GLP-1 $289. Safety add-ons are flat regardless of tier, and vendor volume discounts start at 10 samples / month.
Identity + Purity + Net Content on one public COA — the base scope, included on every peptide.
Base plus Endotoxin (USP <85>) and Sterility (USP <71>). The injectable-grade package.
Base + Endotoxin + Heavy Metals + Sterility + Bioburden. Everything a vendor needs on one COA.
Each category has its own failure modes, its own regulatory ceiling, and its own analytical panel. Dedicated guides explain what gets tested, why, and what a passing result looks like.
We don’t invent our own standard. We follow the compendia — USP, ISO, FDA, GMP — that regulators, retailers, and payors already accept.
Documented method validation, system-suitability criteria, and calibration ranges for every assay. Operated to ISO 17025 expectations across method scope, data integrity, and traceability — independently auditable on request.
USP <61> and <62> for microbial limits, <85> for endotoxin, <51> for preservative efficacy, <232>/<233> for elemental impurities. We follow the compendia; clients can follow along.
Chain-of-custody from sample receipt through retain disposal. Analyst signatures, instrument logs, and retained samples for 90 days. As an analytical contract lab we are not the cGMP filer for finished drug — your downstream QA team uses these records inside their own GMP submission.
21 CFR Part 11 – style audit trails on instrument software. Raw chromatograms and mass spectra retained and available on request to clients and regulators.
Documentation packages that support the safety-substantiation and labeling requirements introduced by the Modernization of Cosmetics Regulation Act of 2022.
EPA 533 / 537.1 for PFAS in drinking water, EPA 200.8 for elemental contaminants (Pb, As, Cd, Hg), EPA 8321 for pesticide residues. Each COA cites the EPA reference number used so the method maps cleanly to regulatory expectations.
