Peptide therapy is gaining attention for its potential applications in weight management, metabolic health, muscle recovery, and healthy aging. This guide explains how peptides work, explores common types such as semaglutide, tirzepatide, retatrutide, BPC-157, and TB-500, and examines their potential benefits and safety concerns. While some peptide-based medications have established medical uses supported by clinical research, many peptides marketed for recovery and anti-aging lack sufficient human evidence. Learn how to distinguish approved treatments from experimental products, understand potential risks, and make informed decisions with guidance from a qualified healthcare professional.
