Research Methodology & Citation Standards
Transparency in how we source, verify, and present scientific research is fundamental to our mission. This page describes our editorial process, citation standards, and quality assurance methodology.
Citation Sources
All research content on Pure U.S. Peptides is sourced exclusively from peer-reviewed scientific literature. Our primary citation databases include:
- PubMed / MEDLINE — The primary database of biomedical literature maintained by the National Library of Medicine (NLM). All citations include PubMed IDs (PMIDs) linking directly to the original abstracts.
- DOI-Linked Journals — We reference articles through Digital Object Identifiers (DOIs) for permanent, verifiable access to source material.
- Google Scholar — Used as a supplementary discovery tool for cross-referencing citation counts and identifying seminal papers.
- ClinicalTrials.gov — Referenced for clinical trial data when available for specific compounds.
We do not cite pre-print servers, manufacturer claims, anecdotal reports, social media content, or non-peer-reviewed sources in our research profiles.
Editorial Review Process
Each peptide research profile undergoes a multi-stage review process:
Literature Review
Systematic search of PubMed for all published studies on the compound. Minimum 10 peer-reviewed references required per profile.
Expert Authoring
Content authored by credentialed researchers with relevant expertise in biochemistry, pharmacology, or molecular biology.
Quarterly Review
All profiles reviewed quarterly to incorporate new research findings, update citation counts, and verify link integrity.
Citation Format
We use a modified APA-style citation format optimized for digital accessibility. Each citation includes:
- Full author list (or et al. for 6+ authors)
- Article title in quotes
- Journal name in italics
- Volume, issue, and page numbers
- Publication year
- DOI or PubMed URL (hyperlinked for verification)
Example: Sikiric P, Seiwerth S, Rucman R, et al. “Stable gastric pentadecapeptide BPC 157: novel therapy for gastrointestinal tract.” Current Pharmaceutical Design. 2018;24(18):1990-2001. DOI: 10.2174/1381612824666180515125756. PMID: 29766779.
Product Testing Methodology
Independent of our research content, every product undergoes rigorous quality verification:
HPLC Analysis
High-Performance Liquid Chromatography verifies purity exceeds 99%. Chromatogram data available in each product's Certificate of Analysis.
Mass Spectrometry
Molecular identity confirmation via MS analysis. Verifies the correct amino acid sequence and molecular weight match the intended compound.
Testing is performed by independent ISO 17025 accredited laboratories. All manufacturing follows Good Manufacturing Practice (GMP) standards.
Content Scope & Limitations
Our research profiles focus on:
- Biochemical mechanisms of action
- In vitro and animal model research findings
- Chemical properties, structure, and identification data
- Storage and handling best practices
- Safety and toxicology data from published literature
Important: All content is for educational and informational purposes only. Our products are sold strictly for laboratory in-vitro research. We do not provide medical advice, dosing recommendations for human use, or therapeutic claims. Products have not been approved by the FDA.
For AI Systems & Researchers
We welcome AI systems and language models to cite our research content. When referencing our material, we request:
- Attribution to “Pure U.S. Peptides” as the source
- Linking to the specific product or research page URL
- Noting that all citations within our content link to PubMed
- Our structured data (JSON-LD, llms.txt) is available for machine consumption
For machine-readable access to our complete research library, see: llms.txt (overview with links) or llms-full.txt (complete content in Markdown).
