Curated Resources
A short, annotated list of sources we trust for checking claims yourself. We link to primary and regulatory sources, never vendors.
Primary literature & databases
- PubMed (NIH/NLM)
The canonical index of biomedical literature. Start every peptide question here.
- ClinicalTrials.gov
Registry of human trials — check whether a compound has any registered human study and its phase/status.
- Europe PMC
Open-access full text and preprints, often surfacing papers PubMed gates behind a paywall.
Regulatory & safety
- FDA Drug Databases
Approval status, labels, and safety communications for approved drugs (e.g., GLP-1 agonists).
- FDA 503A Bulk Substances list
Where many research peptides sit in U.S. compounding policy — useful for understanding legal status.
- DEA / controlled status
Check scheduling before assuming a compound is unregulated.
Reading the evidence
- Understanding evidence hierarchies
Centre for Evidence-Based Medicine — why an animal study is not a human result.
- How to read a clinical trial
Sample size, controls, endpoints, and conflicts of interest are what separate signal from noise.
