Sources we use
Every peptide profile on PeptaHub is built from primary research first. The hierarchy we work from, strongest to weakest:
- Phase 2/3 clinical trials registered on ClinicalTrials.gov or equivalent, with published results in peer-reviewed journals.
- Phase 1 human studies (safety, pharmacokinetics, tolerability), especially where they are the only human data available.
- Peer-reviewed preclinical research — animal models and in-vitro mechanism papers indexed on PubMed.
- Systematic reviews and meta-analyses when they exist and are recent enough to be relevant.
- FDA labels, EMA summaries, and regulatory filings for approved compounds.
- Investigator interviews and lab statements from the research groups actually producing the underlying science (e.g., the University of Zagreb group for BPC-157).
What we do not treat as primary sources: vendor marketing pages, unsourced forum claims, Reddit folklore, telehealth company blogs, and AI-generated summaries of any of the above. These can be useful for understanding what the community thinks, but they are not evidence in the sense this reference uses the word.
