Overview

Precision Mass Spec describes itself as a US-based laboratory offering LC-MS/MS purity and identity testing for research peptides, anabolic compounds, SARMs, and pharmaceutical products. The site states samples are shipped to its US laboratory, with the address provided on order confirmation, and that analysis includes HPLC separation, LC-MS/MS confirmation, calibration standards, and quality controls. Advertised services include peptide purity/identity testing, blind peptide screening, an HGH panel, AAS/hormone analysis, blend analysis, heavy metals and sterility add-ons, with published per-test pricing and volume tiers. Standard turnaround is stated as 48-72 hours, with expedited options. Certificates of Analysis are described as verifiable through a public COA library. Details are summarised from the company's own website and have not been independently audited.

✓
EndotoxinDocumented. Bacterial endotoxin testing is offered.
–
Culture-based sterility (e.g. USP <71>)Not found in public sources. Compendial or culture-based sterility testing. PCR or rapid screens are listed but do not earn this point.
✓
Heavy metals / elementalDocumented. Heavy-metal or elemental analysis is offered.

Quality & reporting

✓
Method detail documentedDocumented. The site documents how analyses are run (instrument, column, detector, reference standards or validation), not just a technique name.
–
Accreditation stated with accreditor or certificate numberNot found in public sources. An accreditation such as ISO/IEC 17025 is stated with the accrediting body or certificate number. 'Pending', 'aligned' or 'compliant' statements do not count.
–
Accreditation found in the accreditor's public directoryNot found in public sources. PAL found the accreditation in the accrediting body's public directory, or a verified owner submitted it and PAL confirmed it there.
✓
Public report verification lookupDocumented. Anyone can check a report's authenticity by ID or QR code.

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.
