Research-grade peptides
for scientists and researchers
who verify what they buy.
The peptide research market runs on trust that is rarely earned and almost never documented. Quartz exists to close that gap. Every decision we make, from sourcing to testing to labeling to batch control, is built to be checked, not taken on faith.
What We Verify & Report
- Identity. Chromatographic confirmation that the compound in the vial is indeed the compound on the label, ensuring accuracy.
- Assay & Content. Confirmation that the stated amount is the amount present, measured by methods appropriate to the material.
Our Key Standards & Values
Purity
We treat purity as one input among several, not as a headline. A purity percentage describes an isolated compound in a simple system. On its own, it says little about identity or about how much active material a given unit contains.
Testing
Every batch is tested by an independent analytical laboratory before release. Certificates are matched to batch numbers so that any vial can be traced to the analysis that cleared it. Each COA reports identity (mass spectrometry), purity (HPLC), lot number, test date and lab.
Sourcing
We source from a small set of qualified manufacturers and hold them to consistent specification. We do not chase the lowest available price at the expense of documentation. Supply is deliberately narrow so that quality control stays legible.
Batch Traceability
Each product carries a batch code in a fixed format. That code ties the vial in your hand to its receive date, its sequence, and its Certificate of Analysis. Nothing is anonymous. Nothing is unaccounted for.
Important
Quartz supplies materials for research use only. Our products are not drugs, are not intended for human or animal consumption, and are not sold for diagnostic or therapeutic use. All claims on this site refer to the identity and content of research compounds, not to any physiological effect.
