Peptides are small molecules made up of amino acids that are linked together through peptide bonds. They play a vital role in many biological processes, including cell signaling, gene regulation, and protein synthesis. Peptides can be found naturally in the body and can also be synthesized and used as drugs, research tools, and supplements. Peptides have wide range of applications like in medical, research, cosmetic and sports related fields. Some common examples of peptides include insulin, which regulates blood sugar levels, and growth hormone-releasing peptides, which have been used to increase muscle mass and strength. Peptides can be taken as supplements or used in skin care products to help reduce wrinkles, improve skin texture, and increase collagen production. However, it’s important to note that not all peptides are safe, effective or legal for human consumption, so it is important to consult with a healthcare professional before using any peptide-based products.
