Overview
Freedom Diagnostics is a US-based peptide testing laboratory located in Franklin, Tennessee, established in 2023. The lab has built a significant volume of work in a short time, publishing more than 40,000 public COA reports as of 2026, making it one of the highest-volume vendor-COA labs in the peptide testing space.
The lab specializes in purity analysis and identity confirmation for research-use-only peptides, serving both commercial peptide vendors and individual researchers who submit samples directly.
Testing Services
HPLC Purity Analysis
Quantitative purity testing using High-Performance Liquid Chromatography with UV detection. Reports the percentage of the sample that is the target compound.
MS/MS Identity Confirmation
Tandem mass spectrometry for compound identity verification. Confirms the molecular weight matches the expected value for the target peptide.
Endotoxin Testing
Available on request. Tests for bacterial endotoxin levels, relevant for injectable preparations.
Net Peptide Content
Quantifies the actual amount of active peptide present in a sample relative to the labeled quantity, distinguishing active compound from fillers or inactive components.
Operational Details
Named signing chemist. Reports carry the name of the analyst who performed the testing, providing a layer of individual accountability.
Published price list. The lab's intake form lists prices per test — purity and identity analysis starts at $200 per sample, with optional net peptide content, endotoxin and sterility testing added on top.
Accreditation Status
Freedom Diagnostics does not claim ISO/IEC 17025 accreditation — the international standard for testing and calibration laboratories — and no accreditation listing for the lab could be found. This is common among peptide-focused testing labs but worth noting: ISO 17025 accreditation provides independent verification that a lab's methods and quality management systems meet internationally recognized standards.
For researchers requiring accredited results for regulatory submissions or formal documentation, this is a relevant consideration. For general quality verification of research compounds, the lab's testing volume and public report database provide a different form of track record.
Limitations
- No ISO/IEC 17025 accreditation is claimed — results may not be suitable for regulatory submissions.
- The lab publishes report results but not its accredited scope or method validation, so the methodology cannot be independently reviewed.
- Relatively new (established 2023) compared to longer-operating labs in the space.
Summary
Freedom Diagnostics is a high-volume US-based peptide testing lab offering fast turnaround (1–3 days) with HPLC, MS/MS, and endotoxin testing. Its public COA database is among the largest in the peptide space, with more than 40,000 reports. It does not claim ISO 17025 accreditation. Reports carry a named signing chemist and can be verified through the lab's public accession-number lookup.
