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.

Others employ penetration enhancers that temporarily increase skin permeability
We do not publish specific dosing here, because dosing for an investigational compound is an individualized medical decision, not advice to follow from a webpage
But protocols save peptides
