The Complete Peptide Knowledge Base

A peptide is a short chain of amino acids — the same building blocks that make up proteins, just smaller. They act as signaling molecules in the body.

Peptides are short (typically 2–50 amino acids). Proteins are longer chains, often folded into complex 3D shapes. Peptides act as signals; proteins do the work.

In the U.S., peptides sold for laboratory research are legal to buy and possess when labeled 'for research use only.' They are not FDA-approved for human use.

A few peptides have FDA approval for specific medical conditions (e.g., semaglutide, tesamorelin, tirzepatide). Most research peptides are sold strictly for laboratory research and are not FDA-approved.

Most research peptides are reconstituted with bacteriostatic water and injected subcutaneously. Some are oral, topical, or nasal — it depends on the peptide.

Sterile water containing 0.9% benzyl alcohol used to reconstitute lyophilized peptides. The benzyl alcohol prevents bacterial growth in multi-use vials.

Lyophilized (freeze-dried) peptides are stored in a freezer. Once reconstituted, they're refrigerated and typically used within 14–30 days depending on the peptide.

Lyophilized means freeze-dried. The peptide arrives as a powder and is reconstituted with bacteriostatic water before use.
