BPC-157 is a synthetic 15-amino acid fragment derived from human gastric body protection compound. It promotes angiogenesis by upregulating VEGF and its receptor VEGFR2, activates the FAK-paxillin pathway to enhance cell migration and wound closure, and modulates the nitric oxide system. It also interacts with the dopaminergic system and has cytoprotective effects on gastrointestinal mucosa, tendons, ligaments, and other connective tissues.

TB-500 (synthetic thymosin beta-4) is studied for its role in actin dynamics, a core process that helps cells migrate, reorganize, and respond to repair signals. Published literature has examined its interaction with angiogenic signaling, inflammatory pathways, and tissue-remodeling biology across multiple preclinical models. The active region LKKTETQ is considered central to its actin-binding activity.

Semaglutide is a GLP-1 receptor agonist that mimics native GLP-1 to stimulate insulin secretion in a glucose-dependent manner while suppressing glucagon release. The Aib substitution at position 2 confers resistance to DPP-IV enzymatic degradation, and the C18 fatty diacid chain enables high-affinity albumin binding, extending its half-life substantially. It also acts on hypothalamic appetite centers to reduce food intake and delay gastric emptying.

Tirzepatide is a dual GIP and GLP-1 receptor agonist that activates both incretin pathways simultaneously. It stimulates insulin secretion, suppresses glucagon in a glucose-dependent manner, and reduces appetite via central and peripheral signaling. The dual receptor engagement provides synergistic metabolic effects beyond GLP-1 agonism alone, including enhanced lipid metabolism and improved insulin sensitivity.

Ipamorelin is a highly selective growth hormone secretagogue that acts on the ghrelin/GHS receptor (GHSR) in the pituitary to stimulate pulsatile GH release. Unlike other GHRPs, ipamorelin does not significantly affect cortisol, ACTH, or prolactin levels at GH-releasing doses, making it the most selective GHS available. It works synergistically with GHRH analogs (like CJC-1295) to amplify GH pulses while maintaining the natural pulsatile release pattern.
