What is a peptide?
A peptide is a short chain of amino acids, the building blocks of protein. Many act like messengers that tell cells what to do. Some are FDA-approved medicines; many are still being studied.
We read the published studies and official records, then rate each peptide by how strong the evidence is and where it stands with the FDA.
Amino Acid Chains
Short sequences of 2-50 amino acids that act as precise biological messengers in cellular systems.
Receptor Specific
Unlike broad-spectrum compounds, peptides bind to specific receptors for targeted biological action.
Rapid Signaling
Many act fast in the body. Researchers are still studying how.
Measurable Biomarkers
Studies measure their effects with lab tests. Results vary, and many are early.

Questions
Platform methodology, data sources, and research scope.
PeptideX is educational only. It is not medical advice, and it does not provide diagnosis, treatment, dosing, or sourcing. PeptideX does not sell, source, or recommend any unapproved drug. It is not affiliated with any drug manufacturer.
FDA approval, where it exists, is specific to a drug product, indication, and route. A paper, a citation count, or a "research use only" label is not an approval.
