No ISO/IEC 17025 accreditation on file
freedomdiagnosticstesting.com 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 freedomdiagnosticstesting.com

US-based peptide testing laboratory in Franklin, Tennessee providing HPLC purity analysis and MS/MS identity confirmation with online COA verification and fast turnaround for individual and commercial clients.

What sets freedomdiagnosticstesting.com apart

  • ✓Highest-volume US peptide testing lab in Peptigrity's database — more published lab tests than any other US-based facility tracked on the platform, across weight-loss, growth hormone, healing, and longevity categories.
  • ✓Dual-method standard on most peptide work: HPLC for quantitative purity and mass spectrometry for identity verification — the two analyses every credible peptide CoA should carry.
  • ✓Same-country shipping for North American buyers — avoids customs delays, returned-package risk, and longer transit times associated with overseas labs.
  • ✓Active in community-facing peptide work. Tests submitted by individual buyers — not just vendor-paid batches — are routinely published, which is the higher-trust submission type for independent verification.
Honest disclosures
  • Accreditation — see the note above.
  • Pricing is not published on the lab's website. Quotes are issued per submission; no public rate card.
  • Turnaround is described by the lab as "rapid" but no specific business-day SLA is publicly committed to. Submitters should request a current estimate when sending samples.
