Why Choose GXG Peptides for Your Research Needs

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), and we post those raw COAs directly on every product page—so you can verify the purity before you buy.

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.
