Individual Peptides Research

This is the full ETHOS US range of individual research peptides: single-compound reference materials supplied for laboratory and in-vitro research. Each listing shows its catalog reference and quantity and, where we can verify them on 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, and each batch COA is published and searchable by lot number in the ETHOS public COA portal. ETHOS runs separate US and UK stores under one brand and one standard; this store serves US orders.
What researchers look for in individual research peptides

Identity. A COA result confirming the compound, normally by mass spectrometry, matched against a reference molecular weight.
Purity and content as separate figures. A purity percentage with its method named, plus the measured amount in the vial.
Lot traceability. A lot number on the vial that matches the published COA.
Clear storage information. Sealed at −20 °C, protected from light and moisture.
