What are peptides?
Peptides are short chains of amino acids linked by peptide bonds. Unlike proteins, which are usually made up of hundreds or thousands of amino acids, peptides typically contain between 2 and 50 units. This structural difference allows them to cross membranes, interact with specific receptors, and perform highly precise signaling functions within the body.
How do peptides work?
Peptides act as messenger molecules. By binding to specific receptors on the surface of cells, they trigger concrete biological responses: hormone release, regulation of metabolic processes, modulation of inflammation, tissue repair, or communication between neurons. Their high specificity is what makes them such valuable tools for scientific research.
What are peptides used for in research?
In the context of scientific research, bioactive peptides are used to study a wide variety of physiological processes. Some of the most explored fields include:
- Tissue regeneration and repair: peptides such as BPC-157 or TB-500 are researched for their potential in wound-healing and recovery models.
- Metabolism and body composition: GLP-1 analogs such as tirzepatide or retatrutide are studied in models of appetite regulation and glucose metabolism.
- Somatotropic axis: secretagogues such as ipamorelin, CJC-1295, or tesamorelin are used to study the pulsatile release of growth hormone.
- Longevity and cellular aging: molecules such as epitalon, MOTS-c, or NAD+ are studied in models of senescence and mitochondrial function.
- Immune system: peptides such as thymosin alpha-1 or LL-37 are researched for their role in immune modulation.
- Central nervous system: selank, semax, and PE-22-28 are studied for their effects on neuroplasticity and the stress response.
Why is purity so important?
A peptide's quality is a determining factor in obtaining reproducible research results. Impurities, contaminants, or batch-to-batch variation can skew experimental data. That's why we work exclusively with lyophilized peptides of 99% purity, verified via HPLC and mass spectrometry, with a Certificate of Analysis (COA) issued by independent laboratories for every batch.
