A peptide is a short chain of amino acids, the building blocks of proteins, that acts like a messenger in your body. Naturally occurring or supplemented, peptides can boost health in big ways: they may speed muscle recovery, enhance fat burning, improve skin elasticity, or support hormone balance. Think of them as tiny tools fine-tuning your system—science-backed and powerful! From better energy to stronger immunity, peptides offer targeted benefits to help you thrive.
