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.
- Accreditation — see the note above.
- 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.
