Individual Peptides

Welcome to the ETHOS UK range of individual research peptides: single-compound reference materials for laboratory and in-vitro research. Each listing gives its catalogue reference and quantity and, where we have verified them against PubChem, reference identifiers such as CAS number, molecular formula, molecular weight and sequence.
Every batch is 8X tested, meaning eight different tests, before it ships. Batch COAs are published and can be searched by lot number on the ETHOS public COA portal or via the ETHOS UK COA page. ETHOS operates separate UK and US shops under one brand and one standard; this shop serves UK orders.
What researchers look for in individual research peptides

Identity. A COA result that confirms the compound, usually by mass spectrometry, checked against a reference molecular weight.
Purity and content reported separately. A purity figure with the method named, and the measured quantity in the vial.
Traceable lots. A lot number on the vial that matches the published COA.
Clear storage guidance. Kept sealed at −20 °C, away from light and moisture.

If you are new to reading laboratory reports, our UK guide on how to read a peptide COA walks through each field.
