Peptides are amino acids that make up proteins. They are found in every tissue and every cell and perform a variety of functions that are necessary to maintain health. Peptides often act as hormones, carrying information through the bloodstream. They can be used to repair tissue and wounds, promote collagen for skin, aid in weight loss, and boost hormone levels-just to name a few! Peptides are typically given through injections and can be tailored to your individual needs.
