Learn About Peptides
Evidence-based information to help you understand what you are looking at before you buy, written in plain language and grounded in how these compounds are actually categorized and studied.
What Are Peptides?
Peptides are short chains of amino acids, the same building blocks that make up proteins, but smaller. In research contexts, peptides are studied for how they signal specific biological processes, from tissue repair to metabolic regulation. Not all peptides behave the same way, and their classification depends on structure, length, and the biological pathway they interact with.
Research Peptides vs. Approved Medications
Some peptide-based compounds, like insulin and certain GLP-1 medications, are approved drugs prescribed by licensed physicians. Research peptides are a different category entirely: they are sold for laboratory and educational research only, have not been approved for human use, and are not evaluated for safety or efficacy outside a controlled research setting. Confusing the two categories is one of the most common and most important mistakes to avoid.
Growth Hormone Secretagogues
This category includes compounds like CJC-1295 and Ipamorelin, studied for their role in stimulating the body's natural growth hormone release pathway. Research in this area focuses on recovery, body composition, and aging-related processes.
Healing and Recovery Peptides
Compounds such as BPC-157 and TB-500 are studied for their potential role in tissue repair and recovery processes. Research in this space is still developing, and findings from laboratory studies do not necessarily translate to human outcomes.
Cosmetic Peptides
Copper peptides like GHK-Cu and signal peptides like Matrixyl are used differently, they are formulated into topical cosmetic products and sold for skin-care use, not injected or ingested. This is why our Skincare category is treated separately from our research peptide catalog throughout this site.
Storage Fundamentals
Most lyophilized (freeze-dried) research peptides should be stored at -20°C and protected from light before use, then refrigerated at 2-8°C once reconstituted, typically for no longer than 14 days. Each product page on this site lists the specific storage guidance for that item, since requirements can vary by compound.
Why Documentation Matters
A Certificate of Analysis (CoA) confirms that a specific batch was tested by an independent lab for purity and identity. Because the research peptide market has seen real cases of mislabeled or contaminated products, we only list items where the supplier provides batch-specific documentation, and we say so clearly on the product page.
