⚠
No ISO/IEC 17025 accreditation on file
Chromate is not currently listed as ISO/IEC 17025 accredited — the international standard for testing and calibration laboratories. This is not unusual in the peptide testing market (most listed labs lack it). Accredited results carry more regulatory weight in formal contexts. Read about lab accreditation standards →

About Chromate

US-based analytical service providing HPLC and LC-MS testing for peptides and dietary supplements with QR-code COA verification and 6 payment options including cryptocurrency.

What sets Chromate apart

  • ✓Public CoA authentication via Job Number + Access Code. Each Certificate of Analysis carries a unique Job Number and Access Code that resolve on Chromate's public `Verify` portal — buyers don't need to take the vendor's word that a CoA wasn't edited or recycled from another batch.
  • ✓HPLC purity + LC-MS identity as standard. Liquid chromatography-mass spectrometry runs alongside HPLC purity work, which is the stricter identity confirmation method on a peptide CoA.
  • ✓6 payment methods including cryptocurrency — Credit card, CashApp, Venmo, Bitcoin, Apple Pay, and Google Pay. The broadest payment menu of any peptide testing lab on Peptigrity.
  • ✓US-based sample receipt for North American buyers — domestic shipping avoids customs delays and overseas transit times.
Honest disclosures
  • No publicly listed ISO/IEC 17025 accreditation. Standard for the peptide testing market.
  • Pricing IS published on the lab's services page — unusual for the sector — but quoted per-test and not bundled into discount packages.
  • Documented mislabeling incidents in early 2025. Chromate initially mis-identified two community-submitted samples (a Cagrilintide labeled as Semaglutide; a Tirzepatide labeled as Retatrutide) before issuing corrected CoAs in later months. Several other labs receiving the same samples (MZ Biolabs, TrustPointe) caught the mislabeling on first pass. CoAs were corrected.
  • Microbiology and endotoxin testing require additional vials submitted alongside the primary HPLC sample.
