Resources
External references
Where to verify claims, read primary research, and check the regulatory status of any peptide discussed on this site.
Every claim on this site should be checkable against a primary source. The links below are the references we use when researching new peptide profiles and when reviewing existing ones. They are grouped by purpose — primary literature for the underlying research, regulatory bodies for jurisdictional status, supplier-evaluation tools for the sourcing question, and sister educational sites for cross-reference.
Primary literature
Where to find the original peer-reviewed papers behind every claim on this site. Most peptide research is indexed in PubMed, but Russian-language literature on Semax, Selank, and Noopept is more reliably found via Europe PMC and direct journal searches.
- PubMed — National Library of Medicine
The standard biomedical literature index. Most peptide mechanism and trial papers are here.
- ClinicalTrials.gov
Searchable registry of registered trials. Useful for confirming whether a compound is in human research and at what phase.
- Europe PMC
Wider coverage of European and Russian journals than PubMed; better for tracking down the original Russian peptide research.
UK & EU regulatory
Authoritative references for the regulatory status statements on each peptide page. If you need to verify the current MHRA position on an unlicensed substance before designing a research protocol, start here.
- UK MHRA — Medicines & Healthcare products Regulatory Agency
UK medicines licensing authority. Search 'unlicensed medicines guidance' for the relevant framework around research-use compounds.
- European Medicines Agency
Centralised EU medicines authority. None of the peptides on this site are EMA-authorised; the database confirms that status.
- Home Office — controlled drugs
Authority on the Misuse of Drugs Act schedules. None of the peptides on this site are currently controlled, but verify before assuming.
- Home Office — Misuse of Drugs Act schedules
The actual current schedule list. Quick check for whether a compound has been added or moved.
Evaluating a research-peptide supplier
Research peptides are sold by many vendors of variable quality. The differentiators that actually matter for research integrity are purity, third-party testing, batch traceability, and supplier transparency — not price.
- Third-party HPLC certificates of analysis
A reputable supplier publishes a batch-specific HPLC purity certificate from an independent lab. Anything else is unverifiable.
- Mass spectrometry confirmation
MS confirmation alongside HPLC verifies molecular identity, not just purity. Look for both on the COA.
- ICH Q3A residual-solvents framework
Background on what residual-solvent specifications mean. Peptide synthesis uses solvents like DCM, DMF, TFA — competent suppliers test for them.
