Freedom Diagnostics Review
Is Freedom Diagnostics legit?
Freedom Diagnostics operates a blind-testing / sample anonymization policy, produces batch COAs for peptide vendors reviewed on Peptide Critic, and accepts mailed-in samples from individual researchers.
Freedom Diagnostics built its reputation on speed: a 24–48 hour turnaround is the operator's stated target, and it's become the highest-volume vendor-COA lab in the space, testing for names like BulkGLP, Honest Peptide, and Modern Aminos. It runs HPLC and MS/MS identity confirmation, tests endotoxin on request, and its reports carry a named, signing chemist plus a public accession-number lookup.
The tradeoffs are real. Pricing isn't published — you'll email for a quote, and figures reported by customers cluster around $200–$400 per test, or $225 for a standard conformity COA. It isn't ISO-accredited, and — more pointedly — community members report Freedom has come up short in independent blind assessments, reportedly failing to correctly identify a sample's actual contents when tested without knowing what it was in advance. That's a meaningful gap for a lab whose entire value proposition is telling buyers the truth about what's in a vial. Freedom is a reasonable, fast option for routine conformity checks, especially for domestic shipping, but pair it with a second opinion before treating any single result as the final word.
Clientele is dominated by vendors — it is the highest-volume vendor-COA lab in the sector, with over 3,000 published reports — but individuals submit directly too. Reports carry a named signing chemist as an accountability signal. Testing is restricted to research-use-only peptides. Pricing is quote-based; the figures shown here are operator-stated and community-reported rather than a published price list.

How to send a sample to Freedom Diagnostics
Ship to Freedom Diagnostics, 133 Holiday Ct Suite 106, Franklin, TN 37067. The process is: complete the peptide purity testing intake form, provide payment authorization, then ship sealed, clearly labelled vials whose lot numbers match the form. Same-lot batch tests must all come from the same lot. The lab does not accept HGH, hCG, large proteins, or non-RUO items.
Trust & methodology
Blind testing / anonymization
Freedom runs no formal blind-testing programme, and publishing to its public database is an optional paid add-on. Community members report that Freedom has recorded shortcomings in independent blind assessments, reportedly failing to correctly identify a sample's contents in at least one such test.
Discrepancy handling
Freedom will not add lot numbers to a report after release except to fix clerical errors — the operator likens doing so to forging a report. Where an endotoxin result comes back positive, the lab may suggest testing another vial from the same batch.

What the community says about Freedom Diagnostics
Recent discussion from the Peptide Critic community forum.
@pepresearcher on their site the COA's are from mdxbiolabs and freedom diagnostics, are those in house?
@randy Do you have any insight on NextGen and Freedom Diagnostics? I noticed some of their COAs are from different companies too - some look more legit than others. Could that mean anything in particular. NextGen has really good marketing and packaging. I'm hoping that isn't a distraction for sub-par products.
I made a purchase this week for the first time from Southern Aminos for 15 vials of AOD-9604. I received 5 vials individually in their casing they provide that match their listing on their site and corresponds to the COA from Freedom Diagnostics (Red cap/Silver crimp and purity of 99.5% and mass of 6.14mg from March…
@Randy Thanks for the update, Randy. Quick question, the vendor being discussed in this thread is Prime Lab, but the finnrick link you shared says Pure Lab Peptides. I appreciate any clarification as I recently made a purchase from Prime Lab after verifying their COA directly on Freedom Diagnostics website.
This is a review for IDUN, who recently had a BOGO deal. I picked up six 30mg GLP-2 vials at a pretty good price, just enough to tide me over while I prepared to place a larger internationally-sourced order.
@pepresearcher just saw it There's been a lot of noise around ION lately — questions about COAs, multiple lab usage, batch failures. I want to share my perspective with you guys directly because this community is where I'd rather have the conversation, not in the TikTok comments.
Hello from Canada. I could not find any Canadian Vendors listed. Any recommendations, as I have not found a USA vendor that will ship to Canada. I found one Canadian vendor that runs the following test: HPLC, UV Detection, and Mass Spectrometry from Freedom Diagnostics, but no Sterility or Endotoxin tests. Thanks
@pepresearcher Yes on the labels you can see completely different purity and mass. But using the same Batch . It seems to me that these older discolored yellow labeled vials are from last years batch that was tested by Chromate and didn't not test for endotoxins as the mass and purity is almost identical to the…
