Peptides are often administered through fatty tissue, either by injection or topical application. Alternatively, peptides can also be administered orally, though this method requires that they be digested first, which can slow down their absorption rate. Fatty tissue is ideal for carrying peptide molecules, as it has a high rate of absorption and stays in the body for longer periods of time. Additionally, fatty tissue also contains plenty of blood vessels, allowing the peptides to be easily delivered to the target location. Ultimately, this approach helps to ensure that peptides can reach their intended destination efficiently and effectively.
