About

CounterionBio is a biotechnology company focused on the science of molecular formulation. We specialize in peptide, protein, and small-molecule drug development-optimizing their stability, solubility, and delivery through advanced counterion and excipient engineering.

Our expertise lies at the intersection of chemistry and biology. By applying deep understanding of ion-pair interactions and formulation thermodynamics, we develop next-generation pharmaceutical and research-grade compounds designed for performance, safety, and reproducibility.

We support research organizations, pharmaceutical developers, and academic institutions with small-scale custom synthesis, analytical characterization, and formulation consulting. Every project is guided by scientific precision, transparency, and a commitment to quality.

At CounterionBio, innovation begins at the molecular level. We aim to transform complex formulation challenges into elegant, scalable solutions that advance the boundaries of peptide and protein science.
