Sources & References

Last updated: June 2026

PeptideTrack is a personal tracking tool. Information in the library is reference material only and is not medical advice, diagnosis, or treatment. Always consult a qualified healthcare professional before starting, changing, or stopping any protocol.

The same sources are available inside the app under Settings → Medical Information → Sources & References, and on each peptide’s detail screen in the Library tab.

Evidence labels in the library

Each library entry includes an evidence label. These describe the type of published support — not a recommendation to use a compound.

FDA Approved — Prescription drugs with FDA-reviewed labeling. See FDA Drug Information.
Clinical Trials — Compounds with published clinical trial data. See ClinicalTrials.gov.
Human Evidence / Human Research — Human studies or limited human research. See PubMed.
Preclinical / Limited Evidence / Research Only — Primarily laboratory or animal research, or sparse published evidence. See PubMed.
Limited/High Risk — High-risk profile. See FDA MedWatch.
Medical Only — Prescription-only; requires specialist supervision. See FDA Drug Information.
