New to peptides and research compounds? This guide covers everything from the basics to building your first protocol — no jargon, no gatekeeping.
Peptides are short chains of amino acids — the same building blocks that make up proteins in your body. Research peptides are synthetic versions of these naturally occurring molecules, designed to interact with specific biological systems.
Unlike pharmaceuticals, most research peptides are sold for investigational and educational purposes. They're used by biohackers, researchers, and health-optimization enthusiasts to explore areas like body composition, recovery, cognitive function, and aging.
Common categories include GLP-1 agonists (for metabolic health), growth hormone secretagogues (for recovery and anti-aging), healing peptides (for tissue repair), and nootropic peptides (for cognitive enhancement). New to all of this? Our in-depth beginner's research guide breaks down each category with examples and protocols.
Peptides work by binding to specific receptors in your body, triggering targeted biological responses. Think of them as highly specific keys that only unlock certain doors — unlike broad-spectrum drugs that affect multiple systems.
For example, BPC-157 promotes angiogenesis (new blood vessel formation) and modulates nitric oxide, which is why it's studied for wound and gut healing. Semaglutide mimics the GLP-1 hormone to regulate appetite and blood sugar. Each compound has a distinct mechanism of action.
Most peptides are administered via subcutaneous injection, though some come in nasal spray or oral forms. They typically arrive as a lyophilized (freeze-dried) powder that needs to be reconstituted with bacteriostatic water before use.
Most people start their research journey with one of these goals. Not sure which fits you? Take our 60-second quiz to get personalized recommendations.
GLP-1 receptor agonists like Semaglutide and Retatrutide are the most researched compounds for weight management, reducing appetite and improving metabolic markers.
Explore compoundsBPC-157 and TB-500 are widely studied for tissue repair, gut healing, and injury recovery — popular among athletes and biohackers alike.
Explore compoundsNootropic peptides like Semax and Selank support cognitive performance, memory, and stress resilience without stimulant side effects.
Explore compoundsEpitalon, GHK-Cu, and growth hormone secretagogues are studied for their roles in cellular repair, skin health, and healthy aging.
Explore compoundsResponsible research starts with proper preparation. These three pillars are non-negotiable — skip any of them and you're taking unnecessary risks.
