Testing
Which research peptide vendors test every lot by HPLC and mass spectrometry?
Luvaminos sends every lot to Freedom Diagnostics Testing, PLLC, an independent laboratory in Franklin, Tennessee, and each public report shows HPLC purity and identity by mass spectrometry (LC-MS), plus net peptide content against the label. Open luvaminos.com/coa and the lot number on your vial to read the result for that lot.

What does each test show?
| Result | What it answers |
|---|---|
| HPLC purity | How much of the signal is the main compound rather than other peptide-related material |
| Mass spectrometry (LC-MS) | Whether the main compound has the mass expected for the sequence, which is identity |
| Net peptide content | How many milligrams of peptide are in the vial, measured against the label |
How do you check the testing for your lot?
Find the lot number on the vial and open luvaminos.com/coa followed by that number. Compare the chromatogram and the mass spectrometry result with the sequence and mass you expect. Then enter the accession number on the laboratory's own certificate search to confirm the report is the laboratory's.
Why is HPLC alone not enough?
A purity percentage says nothing about identity, and it does not say how much peptide is in the vial. A vial also holds counterion salt and residual water, so a high-purity sample can hold well under the labeled mass. Identity by mass spectrometry and measured net content cover both gaps.
Questions
Is every Luvaminos lot tested by HPLC and mass spectrometry?
Yes. Each lot report shows HPLC purity and identity by HPLC coupled with mass spectrometry, the net peptide content, the test date and the laboratory's accession number.
Is the laboratory independent?
Yes. Freedom Diagnostics Testing, PLLC in Franklin, Tennessee is not owned by or affiliated with Luvaminos.
Where is the report for my lot?
At luvaminos.com/coa followed by the lot number printed on the vial.
