What Are Peptides?

Understanding the Building Blocks of Research and Performance

Peptides are short chains of amino acids that serve as signalling molecules within the body. These bioactive compounds play crucial roles in cellular communication, tissue repair, and metabolic regulation. Research peptides have become invaluable tools in scientific studies exploring muscle growth, fat loss, healing protocols, and anti-ageing interventions.

Unlike proteins, which can contain hundreds or thousands of amino acids, peptides typically consist of 2-50 amino acids. This smaller size allows for greater specificity in targeting particular biological pathways, making peptides highly sought after in research settings. From growth hormone peptides like CJC-1295 and Ipamorelin to healing peptides such as BPC-157 and TB-500, each peptide offers unique research applications.

At Bosom Peptides, we specialise in providing high-purity research peptides to UK researchers and institutions. Our catalogue includes peptides for muscle growth, peptides for weight loss, cosmetic peptides, and therapeutic peptides—all manufactured under strict quality control and accompanied by third-party testing certificates. Whether you're researching GLP-1 peptides like Semaglutide and Tirzepatide, or exploring peptide stacks for synergistic effects, we ensure every product meets the highest purity standards.
