Editorial Standards And Research Methodology

Our Sourcing Standards

Each Compound Monograph Is Compiled From Primary And Authoritative Secondary Sources: Peer-Reviewed Literature Indexed In PubMed, Regulatory And Chemical Databases Including ChEMBL, UniProt, And The FDA Unique Ingredient Identifier (UNII) System, And Published Pharmacokinetic Data. Molecular Identity Fields Such As Sequence, Molecular Weight, And Receptor Targets Are Cross-Checked Against These Reference Databases Before Publication.

Our Evidence-Tier System

Every Compound Is Assigned An Evidence Tier That Communicates The Strength And Type Of Available Research At A Glance. Tiers Never Imply Endorsement For Human Use — They Describe The State Of The Scientific Literature Only.

Approved Drug

FDA and/or EMA approved with robust human trial data.

Investigational

In active human clinical trials; not yet approved.

Preclinical

Evidence is animal or in-vitro; no human efficacy data.

Research Compound

No approved human use; sold for laboratory research only.

Cosmetic

Recognized topical cosmetic active, not a drug.

How We Review And Update

Monographs Are Maintained By The Pep Nation Lab Research Team. Entries Are Revised When New Peer-Reviewed Evidence, Regulatory Changes, Or Corrected Reference Data Become Available. Where The Literature Is Preliminary, Conflicting, Or Limited To Animal Or In-Vitro Models, We State That Explicitly Rather Than Overstating Certainty. Confidence Indicators Accompany Referenced Claims So Researchers Can Weigh The Strength Of The Underlying Evidence.

Citations And Corrections

References Are Listed On Each Monograph And In The Machine-Readable Markdown Version Available At Each Compound's Data Endpoint. If You Identify An Error Or Have A Peer-Reviewed Source To Suggest, Contact The Research Team At research@pepnationlab.com And We Will Review It.
