Prices are per sample in USD as of July 2026. ECA prices are from the ECA catalog. Freedom Diagnostics prices are from their published Peptide Purity Testing Intake Form: Purity and Identification is 200 dollars and Net Peptide Content is 25 dollars when bundled, so the 225 dollar figure above matches the same deliverable that ECA includes as standard. Their endotoxin and sterility tests require an additional vial. Confirm current pricing with each lab before ordering.
Freedom Diagnostics is an independent company and is named here only for comparison. Erie Coast Analytical is not affiliated with, endorsed by, or partnered with Freedom Diagnostics.
Why vendors compare Freedom Diagnostics with ECA
Freedom Diagnostics is a US lab with fast turnaround and a large public COA archive. The differences that matter are what comes included in a test and what it costs.
Lower price on every test
ECA is priced below Freedom Diagnostics on every test compared above, including the complete purity, identity, and quantification workup.
Quantification included
ECA includes quantification in the base price of every test. Freedom Diagnostics prices Net Peptide Content as a 25 dollar add-on on top of Purity and Identification.
The same core methods
Both labs confirm purity by HPLC and identity by mass spectrometry. The analysis you get is directly comparable.
Turnaround that holds up
ECA turns results around in 1-2 days. Freedom Diagnostics publishes 24-48 hours, though customer reports suggest 3-5 days in practice.
Both independent, both US-based
Neither lab is vendor-affiliated, and both run analysis in the United States, so there is no customs delay or overseas shipping on either side.
What you still get with ECA
Choosing a domestic lab does not mean giving up the documentation researchers rely on.

Purity-focused chromatography backs the final Certificate of Analysis.
Signed COA
