About us

What We Do

99.8% Purity Standards
Setting the Gold Standard in Research Peptides

At GXG Peptides, we have a single objective: to supply the scientific community with research peptides of verifiable purity. We know that in a laboratory setting, variables ruin data. That is why we treat Quality as a metric, not a buzzword. Every batch we stock is subjected to rigorous third-party analysis (HPLC and Mass Spectrometry).

Beyond the chemistry, we are committed to logistics that respect your research timeline. We offer same-day dispatch (if ordered placed before 1pm cst) to ensure your materials arrive active and secure. With GXG, you get industry-leading purity and responsive US-based support, all at pricing that keeps your project under budget.
