Understanding Peptide Therapy
Peptides are short chains of amino acids that serve as signaling molecules in the body, regulating everything from growth hormone release to immune function, tissue repair, and metabolic processes. Unlike traditional pharmaceuticals that often target a single receptor, peptides work through multiple complementary pathways, making them versatile tools in modern medicine and research.
Categories of Peptide Therapy
Healing & Recovery peptides like BPC-157 and TB-500 have gained significant attention for their ability to accelerate tissue repair. BPC-157, derived from gastric juice, has shown remarkable results in preclinical studies for tendon, ligament, and gut healing through upregulation of growth factors and angiogenesis promotion. Read our Complete Guide to Peptide Therapy for a comprehensive overview.
GLP-1 receptor agonists such as Semaglutide and Tirzepatide represent the most commercially successful peptide-based therapies, with FDA approval for both type 2 diabetes and chronic weight management. Retatrutide, a triple agonist targeting GLP-1, GIP, and glucagon receptors, is showing unprecedented weight loss results in Phase 3 clinical trials.
Growth hormone secretagogues including CJC-1295 and Ipamorelin stimulate natural GH production from the pituitary gland, offering potential benefits for body composition, recovery, and sleep quality without the risks associated with exogenous growth hormone administration.
Cognitive peptides like Selank and Semax, developed in Russia and approved for clinical use there, modulate neurotransmitter systems including GABA, serotonin, and dopamine while promoting BDNF expression for neuroprotection and cognitive enhancement.
