What this site does

pepi.ninja covers two intersecting subjects: (1) the FDA's review and policy framework for compounded peptide preparations, and (2) the publicly available scientific literature on individual peptide molecules.

We are a curator. We do not generate original research. We do not give medical advice. We do not endorse the use of any substance.

What this site does not do

  • We do not sell, distribute, manufacture, or facilitate the sale of any substance.
  • We do not give personalized medical advice.
  • We do not make therapeutic claims. Our peptide pages report what cited sources state, with neutral verbs only.
  • We are not affiliated with any peptide manufacturer, compounding pharmacy, or supplement vendor.

Source whitelist

The only sources we cite as authority:

Peer-reviewed
