Our Mission
Built by researchers, for researchers.
Sten Protocols exists because the research peptide market is broken. Vendors over-promise, under-test, and hide behind disclaimers. We started Sten to flip that: HPLC, mass spec, and accredited third-party labs on every single batch — with the chromatograms published openly.
Verified, Not Promised
Every claim is backed by an independent lab report.
Accredited Labs Only
We work exclusively with ISO 17025 accredited U.S. facilities.
Reproducibility First
Lot-to-lot consistency that your protocol can rely on.
