What this page can say

The names below are facts about certificates we opened. They are not a ranking of laboratories against one another, and they carry no HPLC purity score. Seller certificate tier is still the ranking on every price page.

The purity and dose gate is written and off. We do not invent pass or fail from missing certificates of analysis.

Deferred: HPLC scores, a lab quality letter, and turning the purity gate on. Those need quality data we are entitled to use. They are not shipped.

What we read on the laboratory's own site

Tucson, Arizona, United States. We read the details below on 14 September 2026.

  • HPLC with ultraviolet detection, combined with mass spectrometry

What it says about outside approval: Schedule III licensed facility, United States Drug Enforcement Administration. A DEA Schedule III licence is a permit to handle controlled drugs. It is not proof the lab tests well. We read the site on 14 September 2026 and found no ISO/IEC 17025 claim.

Published prices and how to ship a vial of your own are on the testing page.

How to check a certificate from MZ Biolabs

Disputes and open questions

These are disputes, not proven facts. Each is what a named source reported, with the link so you can read it and decide.

  • Customer complaints about slow price quotes and slow notice that a sample arrived. peptideprotocolwiki.com
  • A review site shows eight open automated warnings across its records. peptidebenchmark.com
  • Directories disagree about its accreditation. Some call it ISO certified, but the lab claims no such thing. chemverify.com

Our notes

  • A user record from early 2025 says this lab correctly spotted wrongly labelled peptides that another lab missed. peptigrity.com
