Chromate Analytical Group LLC
Chromate Analytical Group LLC (operating as "Chromate") · Researched September 26, 2026 · partial profile — some facts could not be sourced
- Website
- chromate.org/
- Location
- Marketed from Hudson, NH per the lab's own contact page; the LLC's registered principal address with the NH Secretary of State is 142 Main St, Nashua, NH — a discrepancy noted by reviewers (source: nhcompanyregistry.com/companies/astra-bioscience-llc/, watchtowerpeptides.com/labs/chromate)
- Founded
- Disputed: site footer reads '© Chromate 2024,' but the underlying LLC (Chromate Analytical Group LLC, NH business ID 1007680) was registered only on 2025-10-23, with sole listed member Astra Bioscience LLC (source: nhcompanyregistry.com/companies/astra-bioscience-llc/)
- Accreditation
- none found
Source: watchtowerpeptides.com/labs/chromate (states Chromate does not hold ISO/IEC 17025 accreditation, does not appear in the A2LA registry, has no CLIA registration, and makes no accreditation claim on its own site)
- Verify a report
- Lab-hosted 'Verify' portal; enter a job number and access code from the COA to pull the report
- What it tests
- Identity (mass spec): LC-MS/HPLC-based identity testing offered for compounds such as semaglutide, tirzepatide, retatrutide (source: chromate.org/services)
- Purity (HPLC): RP-HPLC purity testing offered, positioned as a budget option (source: chromate.org/services)
- Quantity / content: not found — not clearly listed as a distinct line item in sources reviewed
- Endotoxin: Endotoxin Count test offered, $240, kinetic chromogenic LAL method, sensitive to 0.0001 ng LPS (source: chromate.org/services)
- Sterility: Sterility Test offered, $240, qualitative aerobic/anaerobic/yeast assessment by membrane filtration and incubation per USP <71> (source: chromate.org/services)
- Heavy metals: ICP heavy metals testing offered (source: chromate.org/services)
- Published pricing
- Sterility Test $240; Endotoxin Count $240; basic HPLC purity/identity tests community-reported at roughly $100-180 — Chromate does not publish a full fee schedule (source: chromate.org/services, watchtowerpeptides.com/labs/chromate)
- Turnaround
- Standard turnaround reported as 5-7 business days, with some users reporting 3-4 days (source: watchtowerpeptides.com/labs/chromate, thinksteroids.com/community/threads/chromate-analytical-serv)
Track record
- publishedVendor Coastal Peptides publishes a dedicated 'Chromate Reports' category on its own site listing Chromate-issued COAs, indicating ongoing use of the lab by at least one vendor
Published disputes & incidents
- Chromate tested two Coastal Peptides samples labeled as semaglutide (initial test in February 2026 also read semaglutide), but the samples actually contained cagrilintide; Chromate issued corrected COAs in March 2026. Competing labs MZ Biolabs and TrustPointe, sent the same product, correctly identified cagrilintide on first test.
- Chromate tested a Peptide Sciences sample labeled as retatrutide (initial test in February 2026 also read retatrutide), but the sample actually contained tirzepatide; Chromate issued a corrected COA in April 2026. Competing labs MZ Biolabs, TrustPointe, Janoshik, Freedom Diagnostics, and Krause, sent the same product, all correctly identified tirzepatide on first test.
- Reviewers note Chromate's underlying legal entity (Chromate Analytical Group LLC) was formed only in October 2025 despite the site displaying a '2024' copyright date, its registered address differs from its publicly listed contact address, and its sole corporate member, Astra Bioscience LLC, is listed as 'Not In Good Standing' with the NH Secretary of State — raising ownership-transparency questions.
- At least one peptide vendor (Disguised Alpha, per third-party review) has described Chromate as an 'ISO 17025 accredited laboratory' in its own marketing, though Chromate's own site makes no such claim and Chromate does not appear in the A2LA registry — a case of a vendor misrepresenting a testing lab's accreditation status.
Notes
Disambiguation confirmed: chromate.org / Chromate Analytical Group LLC is a real peptide/research-chemical testing lab (New Hampshire), distinct from unrelated industrial/chemical uses of 'chromate.' WebFetch was mechanically blocked in this environment for the whole session; findings rely on WebSearch synthesis, not direct fetches of chromate.org or the NH Secretary of State's own database. Sources disagreed on the mislabeling incident's year ('early 2025' vs 'early 2026'); 2026 is the internally consistent reading (the LLC did not exist until October 2025) and is what's reported, but the discrepancy is flagged. Of the twelve labs researched, Chromate carries the most substantiated integrity and corporate-transparency concerns.
