Understanding Peptide Purity: What HPLC and MS Testing Really Tell You
A breakdown of the two primary analytical methods used to verify peptide identity and purity — and why both matter for reliable research.

Point Break Compounds
The science behind
what we sell.
We built Point Break Compounds on one principle: research-grade materials demand research-grade verification. Every vial is tested, documented, and traceable.
Who We Are
Founded for
researchers.
Point Break Compounds was built to provide the scientific research community with consistently high-quality peptides. Reliable materials are the foundation of meaningful research — we take that seriously.
Every product is manufactured in certified U.S. facilities under WHO/GMP and ISO 9001:2015 standards. We believe in transparency — every order ships with a Certificate of Analysis.

Our Process
Four steps. Zero shortcuts.
01
Sourcing & Synthesis
Raw materials sourced from vetted, GMP-certified manufacturers. Synthesis follows strict protocols in ISO 9001:2015-certified facilities under controlled conditions.
Every supplier is audited before onboarding. We maintain a closed supply chain with full traceability from raw amino acids to finished product.
02
HPLC Analysis
Every batch undergoes High-Performance Liquid Chromatography to confirm peptide identity and measure purity. We require >99% before any product moves forward.
HPLC separates peptide components by molecular interaction, producing a chromatogram that reveals exact purity percentage and identifies any impurities present.
03
Mass Spectrometry
Mass spectrometry confirms molecular weight and structural integrity — a second independent verification of compound identity.
MS measures the mass-to-charge ratio of ionized molecules. If the observed molecular weight doesn't match the expected value within tight tolerances, the batch is rejected.
04
Certificate of Analysis
A full COA is generated for every batch documenting purity percentage, testing methodology, and results. Ships with every order — no exceptions.
Each COA includes: compound name, batch number, molecular weight (observed vs. expected), HPLC purity percentage, appearance, solubility data, and testing lab identifier.

Common Questions
FAQ
No. All products sold by Point Break Compounds are strictly for in-vitro laboratory research and analytical purposes only. They are not approved for human consumption, ingestion, or any form of application to humans or animals.
A COA is a document from an independent laboratory that confirms the identity, purity, and quality of a compound. Every order includes a COA showing HPLC and mass spectrometry results verifying >99% purity.
Each batch undergoes two independent tests: High-Performance Liquid Chromatography (HPLC) to measure purity, and Mass Spectrometry (MS) to confirm molecular identity and structural integrity.
All products are synthesized in the United States in WHO/GMP and ISO 9001:2015-certified facilities that follow pharmaceutical-grade manufacturing protocols.
Lyophilized peptides should be stored at -20°C or below for long-term storage. For short-term storage (under 30 days), refrigeration at 2-8°C is acceptable. Keep vials sealed and away from light and moisture.
Most orders are fulfilled same-day if placed before 2 PM EST on business days. Standard shipping typically arrives within 2-5 business days.
