About PepStack
Evidence-rated peptide research built on transparency, safety, and rigorous methodology.
What PepStack Is
PepStack is an educational information retrieval system that aggregates, indexes, and presents peptide-related data from peer-reviewed literature, government registries, and publicly available regulatory filings. It is designed for clinicians, researchers, and serious self-directed readers who need citation-backed reference material with full source transparency.
Every compound profile leads with published safety data. Every factual claim links to its primary source. Evidence tier ratings reflect the highest phase of human clinical research completed, not an endorsement of efficacy. We document what the literature establishes and what it does not.
PepStack does not provide medical advice, generate personalized recommendations, or ingest biometric data. All content retrieval is user-initiated.
Who Built This
The PepStack team has backgrounds in AI research methodology, data evaluation, physics, and education. We built a custom research workflow for peptide data because existing resources did not meet the standard we wanted: thorough, cited, and honest about what the evidence actually shows.
Data Sources
Every peptide profile is built from multiple primary and secondary research sources. Our pipeline queries 35+ data sources per peptide, including:
PubMed / MEDLINE
Peer-reviewed biomedical literature - the gold standard for clinical evidence.
ClinicalTrials.gov
Registry of ongoing and completed clinical trials, including status and results.
FDA
Regulatory status, approval history, and safety communications.
OpenAlex
Open scholarly metadata for citation analysis and research mapping.
arXiv
Preprint server for cutting-edge research not yet peer-reviewed.
Exa AI
Neural search across the full web for clinical resources and vendor data.
Methodology
Our data pipeline uses a blind multi-model reconciliation process designed to catch errors that any single AI model would miss:
- 1Data Collection: Each peptide starts with 35+ automated research queries - PubMed abstracts, clinical trial registries, FDA regulatory filings, OpenAlex citation networks, arXiv preprints, and neural web search across clinical resources and vendor documentation. This produces thousands of raw data points per peptide before any AI analysis begins.
- 2Independent Analysis: Two different AI models independently analyze the same raw data, producing separate structured profiles without seeing each other's work.
- 3Blind Reconciliation: A third model reconciles the two analyses field by field, flagging discrepancies and resolving conflicts against the original source data. Disagreements are documented, not hidden.
- 4Citation Verification: All study citations are verified against PubMed and ClinicalTrials.gov. Every PMID and NCT identifier links to its source.
- 5Evidence Rating: Each peptide receives an evidence tier based on the quality and quantity of available human clinical research.
Currently tracking 89 peptides with 1,144 cited studies.
Evidence Tier System
Every peptide is assigned an evidence tier based on the strength and quality of available research:
FDA Approved
Approved by the FDA for specific medical use. Full clinical trial data available.
Late-Stage Clinical
Phase 3 clinical trials completed. The compound has undergone large-scale human testing regardless of outcome.
Early-Stage Clinical
Phase 1 or Phase 2 human trials completed. Initial human safety and efficacy data exists.
Limited Human Data
Human data exists but lacks controlled clinical trials. Evidence comes from case reports, observational studies, or pharmacokinetic data.
Animal Studies Only
No human clinical trials completed. All evidence comes from animal models, cell cultures, or in-vitro studies.
Important Disclaimers
PepStack is an educational information retrieval system, not a medical service. We do not provide medical advice, diagnoses, or treatment recommendations. The information presented here is compiled from published research and should not be used as a substitute for professional medical guidance.
Always consult a qualified healthcare provider before starting, stopping, or changing any treatment. Many peptides discussed here are research compounds that have not been approved by the FDA for human use.
