Why US customers look for a Janoshik alternative
Janoshik is a long-standing, high-volume lab, often called a gold standard. For US customers the friction is not the analysis, it is the cost, the logistics of shipping samples overseas, and waiting on results.
Lower prices
ECA is priced below Janoshik on every test compared above, up to 46 percent less on the flagship GLP-1 test, before overseas shipping and rush fees are counted.
US-based lab
Erie Coast Analytical operates in the United States, so domestic customers ship samples domestically and skip the overseas leg entirely.
No customs delays
Domestic shipping avoids the international customs holds and paperwork that can stall overseas sample transit for days or weeks.
Faster turnaround
ECA targets a 1-2 day testing turnaround once a sample is received and logged, versus lead times that can stretch to a month or more at peak.
What you still get with ECA
Choosing a domestic lab does not mean giving up the documentation researchers rely on.
HPLC purity analysis
Purity-focused chromatography backs the final Certificate of Analysis.
Signed COA
Every approved result is issued as a signed Certificate of Analysis.
COA verification
Results can be verified privately or published to the public archive.
