Overview

MZ Biolabs is a Tucson, Arizona-based analytical testing provider that states it uses mass spectrometry and HPLC instrumentation to analyze peptides, small molecules, SARMs, nootropics, and vitamins.

It notes that purity testing does not cover activity, sterility/endotoxins, heavy metals, or pH, and describes bacterial endotoxin and sterility testing as forthcoming rather than currently available. The company states it is a US DEA Schedule III licensed facility (license RP0584676) and serves clients worldwide. Named staff include an analytical chemist/owner, an analytical chemist, a microbiologist, and a facility manager.

Is this your facility?

Claiming is free. PAL first verifies that you are authorized to act for the business. Verified owners can then use three separate routes. Peptide Ad Lab never charges a business to correct a factual inaccuracy.

  • Company-provided updatesYour description, testing services, methods and instruments, facility locations, sample submission link, turnaround, pricing and contact details, shown in a section labelled “Provided by the company”. Not checked by PAL and not used in the score. Free: sent to PAL as correction requests. PAL Pro: published directly.
  • PAL-reviewed evidenceDocuments or links for a scoring criterion. PAL reviews them under the same rule used for every facility; only accepted evidence changes a finding. Any plan.
  • PAL-verified lab credentialsAccreditations such as ISO/IEC 17025. They count only after PAL finds them in the accreditor’s public directory. Any plan.

PAL Pro is an optional paid plan for company-provided updates, extra images and the PAL Pro badge. It never verifies a credential, accepts evidence, or changes a finding, score, eligibility or ranking position.

Ownership verification confirms that you control the business. It is separate from laboratory credentials and from PAL Pro, it is not an endorsement, and it does not change any finding or score.
