How to Find Peptide Studies, Trial Registrations and Regulatory Records
Where to look for published peptide studies, trial registrations, regulator records and anti-doping lists, and how to read what you find without overstating it.

Start with the exact name
Brand names, nicknames and vendor labels change from one product to the next, so searches work best with the official generic name of the active ingredient. The WHO's International Nonproprietary Names (INN) programme gives each pharmaceutical substance a unique, globally recognized name that is public property, also called a generic name. [1] WHO also asks that trademarks not be derived from INNs. [1] Many compounds discussed online have no INN or several informal names; for those, see research peptide naming and identity problems before drawing conclusions from a search.Find published studies
PubMed is the free index of biomedical literature run by the U.S. National Library of Medicine. It holds more than 40 million citations and abstracts, but not full-text journal articles; links to full text appear when available. [2] MEDLINE is the largest component of PubMed, and its records are indexed with Medical Subject Headings (MeSH). [2][3]Useful habits:
- To find systematic reviews, PubMed's publication-type tag for systematic review limits a search to those records. Publication type may be supplied by the publisher or assigned during indexing, so the filter can miss records that are not yet indexed. [4]
- Check each record for linked notices. The National Library of Medicine links original articles to retraction notices, and treats corrections as errata. [5]
- Read the abstract as a summary only. Our guide to the peptide research landscape explains how to weigh what it reports.
Find trial registrations
A registry lists studies, including ones still running or never published.- WHO International Clinical Trials Registry Platform (ICTRP): a WHO platform whose stated mission is to make a complete view of research accessible to people making health care decisions; its page notes that other registries such as clinicaltrials.gov can also be searched. [6]
- EU Clinical Trials Register: information on interventional clinical trials of medicines in the European Union and European Economic Area. [7]
A registration shows what was planned. In the EU register, results are entered by the sponsors themselves and published once validated, so results can be missing or late. [7] Our page on clinical trials for peptides explains phases and what registration does not show.
Find regulator records
| Question | Where to look | What to know |
|---|---|---|
| Is a product FDA-approved? (United States) | Drugs@FDA, searchable by drug name, active ingredient or application number. [8] | It does not include products approved by FDA's Center for Biologics Evaluation and Research. [8] |
| What are its therapeutic equivalents? | The Orange Book lists drug products approved on the basis of safety and effectiveness. [9] | Absence from a list means "not found here", not a verdict. |
| Is a medicine authorised in the EU? | EMA's medicine finder shows centrally authorised medicines that EMA evaluated. [10] | Nationally authorised medicines may be missing; check national registers. [10] |
| How did EMA assess it? | The European public assessment report. [11] | EMA publishes one for each centrally authorised medicine. [11] |
| Is a medicine licensed in the UK? | MHRA Products holds leaflets, product characteristics and Public Assessment Reports. [12] | Covers licensed products. |
| Has FDA taken action against a company? | FDA warning letters. [13] | Matters described may have changed since the letter was issued. [13] |
| Has a safety problem been reported? | FDA MedWatch, which receives reports from the public and publishes safety alerts. [14] | A report records a suspicion, not proven cause. [15] |
| Is it banned in sport? | The WADA Prohibited List, updated at least annually. [16] | Check the current edition and your sport's rules. |
Two cautions apply. First, compounded drugs are not FDA-approved, so a compounded product will not appear as an approved medicine. [17] Second, appearing in any database, for example as an ingredient name, is not approval: the European Commission's cosmetic ingredient database states that an entry does not mean the ingredient is approved for use in cosmetics. [18] Health Canada and Australian (TGA) product registers were not read for this library, so this page makes no statement about them.
A simple search routine
- Write down the active ingredient's generic name and any alternative names.
- Search PubMed by that name, then narrow to systematic reviews.
- Search a trial registry for the same name to see what is planned, running or finished.
- Check the regulator for your country for approvals, labels and warnings.
- Compare what you found with the claim you started from. Our peptide A-Z directory and guide to reading a peptide record show how identity, status and evidence are kept apart. Unfamiliar words are explained in the Peptide Glossary.
If you have had a problem after using a product, see reporting adverse events for peptide products. Rules differ by country, and this page is not legal advice.
Frequently asked questions
Why can't I find a compound in Drugs@FDA?
It may not be an FDA-approved drug, it may be approved under a different name, or it may fall under the biologics center, whose approvals Drugs@FDA reports do not include. [8] Compounded drugs are not FDA-approved, so they will not appear as approved medicines. [17]
Does a trial registration mean a peptide works?
No. A registration records a planned or ongoing study. Results come later, and in the EU register they are entered by the study sponsors. [7]
What does PubMed not give me?
It indexes citations and abstracts and does not include full-text journal articles, though it often links to them. [2]
Where do I check whether a substance is banned in sport?
The WADA Prohibited List states which substances and methods are prohibited in sport and when. [16] See also anti-doping rules for peptides.
Does a warning letter tell me a product is unsafe or unlawful today?
It describes matters at the time of the letter, and FDA notes later interaction with the recipient may have changed the regulatory status. [13] See regulatory warning letters and alerts for peptides.
