Epitalon analysis

Small tetrapeptide — tiny vials, frequent shortfall.

Epitalon vials are usually 10 mg. At that size an underfill of 2 mg is a 20% shortfall that nobody notices without an assay.

What this test tells you

Confirms the molecule is what the label claims, by measuring the mass of the eluting ions. Catches substitution and the wrong compound entirely.

How much is actually in the vial, compared against the declared strength and reported as a percentage of claim.

Area percent of the main peak, with the chromatogram attached so the figure can be checked rather than trusted.

A report ID and unique key that resolve to a public record. Anything that does not resolve is not a genuine report.

Frequently asked questions

Do you test the capsule form?

Yes, content is reported per capsule rather than per vial.
