Peptide
General Peptide delivers pure research compounds with comprehensive verification, 100% USA third-party testing, and complete transparency on every batch. Built for researchers who refuse to compromise on data integrity.
Built on Four
Commitments
Comprehensive COAs
on Every Batch
Most suppliers test for purity. We go further — verifying everything purity testing cannot see.
A compound can appear analytically pure and still contain contaminants that compromise experimental results. Our comprehensive verification protocol addresses the full picture — not just what the compound is, but what else may be present.
Every Certificate of Analysis is independently generated by ISO 17025-accredited U.S. third-party analytical laboratories — with zero in-house testing — and published at generalpeptide.com before any order is placed. Batch-specific. Never generic. Never on request only.
-
01
HPLC Purity AnalysisQuantifies compound purity against total UV-absorbing material. General Peptide standard: ≥99%. Full chromatogram data included in every COA.
-
02
Mass Spectrometry IdentityESI-MS or MALDI-MS confirms exact molecular weight matches the expected compound — verifying correct amino acid sequence and modifications.
-
03
Net Content VerificationIndependent confirmation that labeled content (mg) matches actual measured quantity. Ensures reproducible research inputs across lots.
-
04
Heavy Metal ScreeningScreens for toxic metals at trace sensitivity — contaminants invisible to standard purity testing that can originate from synthesis reagents.
-
05
Microbiological ContaminantsTests for microbial contamination that can compromise cell-based research systems and confound biological activity data.
-
06
Residual SolventsScreening for synthesis-derived solvent residues that may persist through purification and represent potential analytical interference.
