Real, actively growing, independently verifiable via a large public COA database, used by multiple unrelated vendors. Not ISO 17025 accredited, and CLIA registration alone does not cover research peptide analysis — a meaningful but disclosed limitation, not a fraud signal.
Freedom Diagnostics is an independent commercial testing lab in Franklin, Tennessee, offering HPLC-UV and LC-MS/MS purity testing, mass-spec identity confirmation, and LAL endotoxin testing for research peptides, under CLIA registration #14D2263999.
Freedom Diagnostics holds a CLIA registration (#14D2263999) but is NOT ISO/IEC 17025 accredited — not found in A2LA, PJLA, or ANAB registries. CLIA covers clinical diagnostic testing, not research peptide analysis, so it does not substitute for a formal analytical accreditation.
The lab's public COA database is live and has grown from roughly 36,600 entries (June 2026) to over 50,800 entries as of this check — real, ongoing growth that indicates active, continuing operation rather than a stagnant or abandoned dataset. Multiple independent 2026-dated sources confirm the CLIA number and Franklin, TN address. Multi-vendor usage previously confirmed (RUO Science, Oath Research, Modernaminos, AminoUSA all independently use this lab).
Could not reach CMS's own federal CLIA lookup directly this session — every third-party CLIA aggregator tried was Cloudflare-blocked. CLIA status is corroborated via multiple independent secondary sources, not confirmed against the primary federal registry itself.
No physical address appears on the COA documents themselves (only "Proudly Owned and Operated in the USA") and no accreditation number is printed on the COAs — the address and CLIA number used here come from independent research, not the documents a buyer would actually receive.
