Beginner's Guide to Peptides
New to peptides? Start here. What they are, how they work, and how to get started safely with research.
What Are Peptides?
Peptides are short chains of amino acids — the building blocks of proteins. When the chain is under ~50 amino acids, we call it a peptide. The body naturally produces thousands of peptides that act as signaling molecules, hormones, and structural components.
Why Do Researchers Study Them?
Peptides are highly specific in their activity, generally well-tolerated, and can be synthesized with high purity. This makes them attractive for investigating targeted biological mechanisms with fewer off-target effects than small molecules.
Common Research Categories
• Growth hormone peptides (CJC-1295, Ipamorelin)
• Healing & recovery (BPC-157, TB-500)
• Weight/metabolic (Semaglutide, Tirzepatide)
• Melanocortin system (Melanotan II)
• Cognitive (Semax, Selank)
Getting Started
1. Start with one compound and understand its mechanism
2. Source from a reputable supplier with third-party COAs
3. Store properly (most require refrigeration or freezing)
4. Follow reconstitution protocols carefully
5. Document everything
