Our Story
The research peptide market has long been plagued by inconsistency. Vendors making purity claims without public verification. Certificates of analysis that can't be independently confirmed. Compounds that don't match their labels.
Stillwater BioLabs was created to be different. We believe that the foundation of good research is good materials—and good materials require verifiable quality. That's why every batch we sell undergoes independent HPLC and mass spectrometry testing, with results published publicly and linked to specific lot numbers.
Our name reflects our philosophy. Still water runs deep. Beneath a calm surface lies rigorous methodology, meticulous quality control, and an unwavering commitment to the research community.
Our Values
The principles that guide everything we do
Precision
Every compound is synthesized to exacting standards and verified through independent analytical testing. We accept nothing less than 99%+ purity.
Transparency
Public, batch-linked certificates of analysis. Full HPLC chromatograms and mass spectrometry data available for every product we sell.
Integrity
We exist to serve the research community. Every decision we make—from sourcing to shipping—prioritizes the quality and reliability of our products.
Our Testing Process
Four steps. Zero shortcuts.
Synthesis
Peptides are synthesized using solid-phase peptide synthesis (SPPS) in cGMP-compliant facilities with rigorous quality controls.
HPLC Testing
High-Performance Liquid Chromatography confirms purity levels. We require ≥99% purity for every batch before it enters our catalog.
Mass Spectrometry
Mass spec analysis verifies molecular identity, confirming the compound matches its expected molecular weight and structure.
Certificate Issued
A batch-linked Certificate of Analysis is generated and made publicly available, complete with chromatograms and test data.
2-Day Shipping from Cold Storage
