Chromate · Hudson, New Hampshire, USA
Legitimacy review
Chromate is a legitimate operating New Hampshire analytical-testing company with transparent pricing and a working record-specific verifier. Its corporate history is short, technical leadership and facility details are limited, and no formal accreditation scope was located.
The New Hampshire registry identifies Chromate Analytical Group LLC, business ID 1007680, as a member-managed company formed October 23, 2025 and currently in good standing. Its principal office is 142 Main St., Nashua; members are Astra Bioscience LLC and Ethan Bradley. The public site lists only Hudson, New Hampshire, and does not explain whether that is the testing, mailing, or service location.
Good-standing state entity record, published service menu and prices, sample workflow, public two-part verifier, and recurring multi-vial reports.
Chromate does not publish an ISO/IEC 17025 certificate, accreditor, certificate number, or peptide-testing scope. Industry-standard and literature-based method language does not constitute accreditation.
Chromate publishes peptide HPLC services, qualitative and quantitative analysis, USP <71> sterility, and kinetic chromogenic LAL endotoxin, with prices but no firm general turnaround.
Community sources describe successful testing and favorable cross-lab comparisons alongside alleged early misidentifications and variable turnaround. The strongest adverse claims lack a complete public primary-report and custody record.
Technical leadership, exact testing-site relationship, accreditation, and the primary records behind alleged early misidentifications remain unresolved. Registered-office and laboratory addresses can legitimately differ; the discrepancy is a diligence question, not a negative conclusion. Different-vial cross-lab comparisons do not establish which result is correct.
The live New Hampshire registry identifies Chromate Analytical Group LLC, business ID 1007680, as a good-standing domestic LLC formed October 23, 2025. It lists Ethan Bradley and Astra Bioscience LLC as members and a Nashua principal office. The same registry currently shows Astra Bioscience LLC in good standing, correcting a stale secondary claim that it had lapsed.
Chromate's site lists Hudson, New Hampshire without a street address, while the state record lists Nashua. Those may be different legitimate business and testing locations, but the relationship is not publicly explained. The domain dates to August 2021 and the terms to May 2024, preceding the current LLC, so the earlier operating continuity remains an open question rather than a negative finding.
Chromate says its tests are qualitative and quantitative HPLC unless otherwise specified, and reviewed reports show RP-HPLC UV or HILIC-HPLC UV. Its current peptide menu ranges from $180 to $420 depending on the analyte, with supplement testing at $120, sterility at $240, endotoxin at $240, and additional peptide vials at $50. No general turnaround promise is published.
The site describes USP 71 sterility by membrane filtration and kinetic chromogenic LAL endotoxin. A vendor transcription for one job instead describes a BacT/ALERT method under a different USP reference; the issuer report and service date would need review before treating that as a contradiction. PeptideCritic's broad LC-MS/MS characterization was not corroborated by the current first-party pages or sampled reports.
Chromate verification requires the Job Number and Access Code printed on the certificate. Exact records follow the official verify route with both values and open a specific Secure DocuView result; a tested job opened without login. The returned artifact may be an image rather than a PDF, so PeptidePrices should preserve the exact record destination and make the required identifier pair copyable.
Representative jobs show multi-vial and multi-panel reporting, including job 28928 with three GHK-Cu samples and job 30325 with two FOXO4-DRI samples. A verifier match authenticates Chromate's published record and fields. It does not prove that a vendor's sold batch or the user's vial is the tested sample.
PeptideCritic and another secondary reconstruction allege two early-2025 compound misidentifications that were later corrected after other laboratories tested related material. The public summaries do not expose enough original issuer records and chain-of-custody evidence to present those allegations as settled analytical findings.
Other community evidence includes a favorable blind retatrutide comparison and reports of turnaround ranging from roughly one to eight weeks. These self-selected examples support visible use and a mixed service record, not a proficiency conclusion. Current example reports took roughly nine to sixteen calendar days from receipt to production, but three documents are not a service-level guarantee.
COA verification
Submit the certificate's job number and access code to the official registry and compare the returned record with every retained page.
Result handling
Use only when the official destination returns the same identifier and the material certificate fields agree.
Use only after a functioning official lookup explicitly returns no record for the submitted identifier.
Use when the official destination resolves the identifier but returns a different report, product, batch, or other material identity field.
CAPTCHA, login, timeout, rate limit, outage, or an unusable response remains portal unavailable, not an invalid certificate.
Not applicable to the current Chromate adapter; use unresolved when either half of the job/access pair is missing.
Use when the issuer identity, required identifier, or official workflow cannot be established from the available evidence.
Certificate structure
Retain and display every page in order. Chromate reports in the corpus range from 1 to 4 pages.
Keep purity, identity, quantity, endotoxin, sterility, heavy metals, and other panels distinct. Chromate's service catalog does not prove that an individual report includes each test.
Evidence boundaries
Review receipts
Public search record
Chromate has a clear official pricing and service footprint, public verification links, dedicated third-party review pages, and recurring Reddit comparisons with other labs. PeptidePrices can add value by documenting the exact job/access workflow and report-level limitations.
Sources
Reusable integration rule: For future vendors, capture job number and access code separately, store the exact official ?c= destination and response fingerprint, preserve every page, and compare all material fields before product matching.

The reviewed sources did not establish that vendors can purchase a passing result from Chromate. That is not an audited independence guarantee: sample selection, who pays, publication rights, blind-testing controls, and correction history still matter.
Physical-vial custody is unknown unless a documented chain connects the tested sample to the specific vial in hand.
CAPTCHA, login, timeout, rate limit, outage, or an unusable response remains portal unavailable, not an invalid certificate.
