What Are Peptides and Why Are They Essential for Bodybuilding?
Peptides are naturally occurring compounds in the body composed of short chains of amino acids. Unlike full-length proteins, peptides are small enough to be easily absorbed and act as signaling molecules, triggering various physiological responses. For bodybuilders, peptides target key areas like growth hormone stimulation, muscle repair, and fat metabolism.
Peptides are especially popular because they:
- Promote lean muscle growth.
- Accelerate recovery.
- Support fat loss.
- Improve joint and tendon health.
- Enhance overall athletic performance.
Unlike anabolic steroids, peptides work by enhancing natural processes in the body, offering a safer and more sustainable approach to bodybuilding.
