Our mission
Research-first.
Always.
Peptide United exists to bring the same rigour to peptide information that researchers expect from primary literature — without the commercial noise.
What we are
- ✓A research encyclopedia covering 100+ peptide compounds
- ✓Synced with PubMed for up-to-date study references
- ✓Written for clinicians, researchers, and informed enthusiasts
- ✓Committed to evidence ratings and source transparency
- ✓Free at the core — summaries are always accessible
What we are not
- —A medical advice service — nothing here is clinical guidance
- —A peptide vendor or supplement retailer
- —Affiliated with or endorsed by any pharmaceutical company
- —A replacement for consulting qualified healthcare professionals
- —Making any claims about treating, curing, or preventing disease
Research methodology
How profiles are built
PubMed literature search
Every profile begins with a structured search of PubMed using compound-specific MeSH terms and chemical synonyms. We index studies from peer-reviewed journals and flag preprints separately.
Evidence classification
Studies are classified by type (RCT, observational, in vitro, animal model) and assigned evidence ratings. We distinguish between human and preclinical data and do not conflate animal findings with clinical evidence.
Mechanism synthesis
Mechanism of action profiles are synthesised from primary literature and review articles. We cite specific pathways, receptors, and signalling cascades where established by research.
Pharmacokinetic data
Half-life, bioavailability, and route data are drawn from pharmacology studies and clinical pharmacokinetics literature. Where data is limited or conflicting, this is explicitly noted.
Regulatory status
Regulatory classifications are checked against FDA, EMA, and TGA databases. Research status badges reflect the current state of clinical development, not commercial availability.
Continuous PubMed sync
Profiles are connected to live PubMed searches that sync daily. New studies are surfaced and flagged for review, ensuring profiles stay current with the literature.
Data sources
Where the data comes from
PubMed / NCBI
Primary source for peer-reviewed studies, abstracts, and MeSH classifications.
DrugBank
Pharmacological data, molecular properties, and drug interaction references.
FDA Drug Database
Approval status, scheduling, and regulatory classification.
ChEMBL
Bioactivity data, assay results, and target information.
ClinicalTrials.gov
Ongoing and completed human trial registrations and results.
UniProt
Protein target data for mechanism of action profiles.
