Freedom Diagnostics Testing is a peptide testing lab in Franklin, Tennessee that reports identity, purity and net content, and lets anyone look up its certificates by search code on its own website. It's the lab named most often across vendors in our directory: 28 of them cite it as of October 21, 2026.
Notice: Research peptides are sold for in-vitro laboratory research only. They are not FDA-approved, not for human or animal consumption, and this page is not medical advice. It contains no dosing or use guidance.
This profile covers who the lab is, what it tests, how to check one of its reports, and the limits of what a report proves. For the basics of reading any certificate, see how to read a peptide COA.
Who runs Freedom Diagnostics
The lab's website and privacy policy give its address as 133 Holiday Ct, Suite 106, Franklin, TN 37067, flagged on the homepage as a new location. The site calls itself "Freedom Diagnostics Testing" in its copyright line. We didn't find a legal entity name, such as an LLC or Inc., anywhere on the site.
"Freedom Diagnostics" is a common business name, so make sure you're looking at the right company. The certificates we opened point to freedomdiagnosticstesting.com and an @FreedomDiagnostics.net contact address. A report that points anywhere else isn't from this lab.
Accreditation. The site's COA lookup page describes the lab as "Compliant with ISO 9001" and refers to Good Laboratory Practice. We found no ISO/IEC 17025 accreditation claim, accrediting body or certificate number on the site as of October 21, 2026. ISO 9001 is a quality-management standard. It isn't a lab competence accreditation like 17025.
What it tests and what it costs
The lab's intake form, posted in May 2026, lists these options:
| Test | Listed price | What the form says |
|---|---|---|
| Purity & identification | $200 | HPLC and/or mass spectrometry |
| Net peptide content | $25 (with purity & ID) | Peptide content excluding water, salts and counterions |
| Endotoxins | $175 | Needs one extra vial |
| Sterility screening | $150 | PCR-based screen for microbial DNA; extra vial |
| Conformity testing | $50 per extra vial | Compares vials from the same lot |
| Fentanyl screen | $40 | Research-use screen |
Heavy metals testing isn't on the form. The site promises quick turnaround but doesn't publish a timeframe.
The certificates we opened match this menu. An August 2026 report lists identity by LC-MS, purity by HPLC-UV and net content in mg, with a chromatogram and mass confirmation. A February 2026 BPC-157 report we checked came with a separate endotoxin certificate that cites USP <85>. Note that the PCR sterility screen detects microbial DNA. It isn't the 14-day culture test described in USP <71>, so read "sterility" on these reports with that in mind.
How to verify a Freedom Diagnostics report
- Find the Search Code. It's in the top-right table of the certificate. The lab's lookup page says it's the first four characters of the client's name followed by the accession number, for example a client "Trus" plus "2608040644."
- Type the lab's address yourself. Go to freedomdiagnosticstesting.com and open COA Look Up. Don't rely on a "verify" link inside a vendor's PDF.
- Search. Enter the code without spaces (it isn't case-sensitive), or search the exact client name shown on the COA. The page says over 40,000 public COAs are available.
- Open the lab's PDF and compare it with the vendor's copy: accession number, dates, product, lot, purity, identity and net content should match exactly.
- Check the lot. The lot number on the report should match your vial. If the vendor sells several lots, make sure you're reading the right one.
A name search can return many reports for one client. That's useful: you can see how often a vendor tests and whether results stay consistent across lots.
What a Freedom Diagnostics COA does and doesn't prove
| It shows | It doesn't show |
|---|---|
| The lab issued a report under that accession number | That the sample came from the lot you received |
| Purity and identity of the sample the lab received | That every vial in the lot matches |
| Net content in mg for that sample | Sterility by culture, unless a separate test was run |
| Endotoxin result, if that certificate exists | Heavy metals (not on the published menu) |
| Who the client was | Storage and shipping conditions after testing |
The client supplies the sample, the product name and the lot number. A vendor can choose which vial to send. Customer-submitted programs, like the one in our Finnrick explainer, test what buyers actually received, which is why we weigh both. Our HPLC purity guide explains why two labs can disagree by fractions of a percent, and our endotoxin guide covers what an endotoxin pass means.
