MZ Biolabs 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 MZ Biolabs

US-based, DEA Schedule III licensed analytical laboratory using QTOF mass spectrometry and HPLC for peptide, SARMs, and research compound testing. Serves commercial clients with a 4-sample monthly minimum.

What sets MZ Biolabs apart

  • ✓DEA Schedule III licensed. One of the few peptide testing labs holding a DEA license — relevant for vendors and researchers handling Schedule III compounds where lab licensing is a procurement requirement, not an option.
  • ✓Research-grade mass spectrometry instrumentation. Bruker QTOF accurate-mass spectrometers paired with Waters Acquity UPLCs (the same chromatographic platform used in pharmaceutical QC), plus a Thermo LTQ Velos Pro ion trap with nanoAcquity for low-abundance detection. Sensitivity to 5 pg/ml exceeds what HPLC-UV alone can resolve.
  • ✓GLP-validatable methods — methods can be validated under Good Laboratory Practice conditions when client requirements demand it, a higher regulatory tier than the unvalidated methods used by most peptide-market labs.
  • ✓Documented accuracy on mislabeled samples. In community-documented early 2025 testing, MZ Biolabs correctly identified mislabeled peptide samples (Cagrilintide submitted as Semaglutide; Tirzepatide submitted as Retatrutide) that another major peptide lab initially mis-identified.
  • ✓Custom method development for compounds not on standard menus — useful for novel peptides where validated methods may not yet exist.
Honest disclosures
  • No publicly listed ISO/IEC 17025 accreditation. Methods can be GLP-validated, which is a different regulatory framework (GLP governs non-clinical laboratory studies; ISO 17025 governs testing-lab competence).
  • Endotoxin testing is $175 per USP <85> (two replicates); capsule identification and quantification testing starts at $350 — community-documented pricing as of early 2025. Chemical purity testing does not include activity, sterility, heavy metals, or pH (those are separate analyses).
  • DEA Schedule III license restricts the lab's scope of accepted samples; not every research compound is in scope. Buyers should confirm acceptance before shipping.
