This three-lecture course defines peptides as short amino-acid chains that act as signaling molecules, then examines their use in tissue repair and metabolic control, and finally weighs their potential in longevity research against current safety limits. Lecture 1 distinguishes peptides from proteins by length (2–50 amino acids) and describes how they bind cell receptors like keys in locks; it notes that insulin was the first peptide synthesized and frames peptides as the body’s “software” that directs cellular hardware. Lecture 2 covers BPC-157, derived from gastric juice, and its role in angiogenesis and tendon repair, then explains how GLP-1 agonists such as semaglutide mimic natural hormones to regulate blood sugar and appetite with greater specificity than older drugs. Lecture 3 reviews GHK-Cu for collagen synthesis in skin and Epitalon’s proposed effects on telomeres and the pineal gland, while stressing that many compounds sold online lack verified purity and long-term human data. The course closes by underscoring the need for medical oversight when moving from broad pharmaceuticals to precise biological signals.
