If you're brand new to peptides and biohacking, this is the place to begin. We'll walk you through everything you need to know before diving in.
What Are Peptides?
Peptides are short chains of amino acids — the building blocks of proteins. Your body naturally produces many peptides that serve as signaling molecules, telling your cells what to do. Synthetic peptides are lab-made versions designed to mimic or enhance these natural signals.
Different peptides have different functions. Some are studied for tissue repair (like BPC-157), others for growth hormone release (like CJC-1295 and Ipamorelin), and others for cognitive enhancement (like Selank and Semax). The key thing to understand is that the research is still evolving — many peptides have strong preclinical data but limited human clinical trials.

A Certificate of Analysis (COA) is a document from an independent laboratory that verifies what's actually in a product. It's the single most important thing to check before purchasing any peptide.
Key things to look for on a COA:
- Purity percentage — Look for 98% or higher.
- Testing method — HPLC is the gold standard.
- Mass spectrometry data — Confirms molecular weight.
- Third-party lab name — Must be independent.
- Batch/lot number — Should match your product.
Safety First
Before exploring any peptide, understand the safety landscape. Most peptides lack long-term human clinical data, and quality varies wildly between vendors.
Explore Compounds
Now that you have the basics, explore individual compounds to understand what the research says about each one:
