Certificate of Analysis
Every peptide we sell is third-party tested, with full documentation of purity and identity verification. Certificates are being onboarded and post per batch as lab results return.
Transparency you can trust
A Certificate of Analysis is your proof that what’s on the label is what’s in the vial. We believe in complete transparency, on every order.
Our testing methods
HPLC purity analysis
High-performance liquid chromatography separates and quantifies peptide components to verify the 99%+ purity standard.
Mass spectrometry
Precise molecular-weight measurement confirms peptide identity and structural integrity against the specified sequence.
Identity verification
Sequence confirmation ensures the compound in the vial matches the labeled research reference — no substitutes.
Batch documentation
Each batch is accompanied by documented quality controls tracking identity, content, and appearance prior to release.
