Where MZ Biolabs stands out

QTOF is genuinely top-tier instrumentation — high-resolution accurate-mass identity work beyond what standard quadrupole LC-MS resolves.

DEA licensure means they can lawfully handle scheduled compounds most peptide labs must refuse.

Real scientific depth: custom method development, metabolomics, and proteomics for institutional collaborators.

Where Gold Standard differs

We're productized where they're institutional: published flat pricing, two-minute online intake, prepaid labels, and 5–7-day standard turnaround versus engagement-based work.

Public verification: every GSA certificate resolves in an open registry — built for vendors whose customers want to check the COA themselves.

A published safety-panel menu (USP <85>, <71>, <232>) with flat prices alongside the base COA.
