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.
- Accreditation — see the note above.
- 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.
