Peptides are made from amino acids that are linked together. They can be thought of as a small protein. They have many functions in the body including signaling and messaging. Some may act like neurotransmitters, while others may act like hormones. They bind to receptors on the cell surface and tell other cells and molecules what to do. Peptides are very specific which makes them safe, well tolerated and more importantly allow them to control and influence how our bodies react to physical exercise and diet. As of January 2015, there were over 60 US FDA-approved peptide medications, 140 peptide drugs being evaluated in clinical trials, and 500 in pre-clinical development.
As we age, production of essential amino acids and peptides decreases. As a result, our bodies begin to show signs of aging and cease to perform at an optimal level.
Most peptide medications are administered subcutaneously but can also come in the form of transdermal creams, nasal sprays, and oral tablets.
