Some of the most common classes include: Hormonal peptides like Tesamorelin or GH-releasing peptides , which regulate growth hormone output Repair peptides like BPC-157 and TB-500 , which aid in tissue regeneration and wound healing Metabolic peptides such as CJC-1295 or GLP-1 analogs , which influence fat loss and insulin response Muscle-building peptides including IGF-1 LR3 and PEG-MGF , which promote hypertrophy and muscle recovery Peptides function as highly specific signaling molecules in the endocrine, nervous, and immune systems and their therapeutic potential continues to grow.
