Built for Researchers
Who Demand Proof
Prism Peptides was founded on a single premise: research-grade means independently verified, fully documented, and traceable from synthesis through delivery.
Eliminate Guesswork
from Research
Too many researchers waste time, resources, and credibility on compounds that don’t meet specification. Unlabeled purity. Missing documentation. Inconsistent results.
We built Prism Peptides to solve this problem. Every compound we ship exceeds 99% purity, verified by independent US laboratories. Every lot comes with complete analytical documentation. No exceptions.
Your experimental outcomes depend on the integrity of your starting materials. We take that responsibility seriously.
Four Pillars of Quality
Every compound passes through our rigorous quality system before reaching your lab.
Precision Synthesis
Solid-phase peptide synthesis using pharmaceutical-grade Fmoc amino acids and optimized coupling protocols. Every sequence built to exacting specifications.
HPLC Purification
Preparative reversed-phase HPLC under optimized gradient conditions. Fractions below our >99% purity threshold are discarded, never shipped.
Independent Verification
US-based accredited laboratories conduct HPLC purity analysis and mass spectrometry identity confirmation. No in-house testing, no conflicts of interest.
Full Documentation
Complete Certificate of Analysis with full analytical data published on every product page. Review the evidence before you order — always.
We Publish Everything
Most suppliers make you request COAs after purchase. We publish them upfront — on every product page, for every lot — because we believe you should verify before you buy.
- HPLC chromatograms with purity percentage
- Mass spectrometry identity confirmation
- Lot numbers traceable to test dates
- Independent lab name and credentials
