About Us
Who We Are
Star Valley Peptides is a US-based research peptide company with direct manufacturing operations in China. We are not a reseller or distributor — we are the source.
This structure gives our customers something most suppliers cannot offer: factory-direct pricing, full batch traceability, and the ability to customize testing protocols to meet specific research requirements.
Why Source Manufacturer Matters
Most peptide suppliers sit between you and the actual manufacturer. That distance creates opacity — in pricing, in documentation, and in quality control accountability.
As the manufacturer, we control every stage of production:
- Solid-phase peptide synthesis (SPPS) in ISO-certified facilities
- HPLC purification to ≥99% purity
- Lyophilization and vial preparation
- Third-party release testing through ISO/IEC 17025 accredited laboratories
- Batch documentation and reference sample retention
When you order from Star Valley Peptides, you are ordering from the facility that made the compound — not from someone who ordered it from that facility.
Our Quality Standard
Every batch ships with a fully verifiable Certificate of Analysis:
- HPLC purity ≥99% — with the actual chromatogram, not just a number
- Mass spectrometry (MS) for molecular identity confirmation
- Endotoxin screening — LAL test, <0.1 EU/mg
- Net peptide content and water content
- Third-party COA with QR code or serial number — verifiable directly on the issuing lab's portal
We support independent re-testing. If your re-test results deviate from our COA by more than 1% purity, we cover the testing cost and issue a full refund. For orders $10,000+, we coordinate simultaneous shipment to your preferred laboratory.
