The peptide library

# Know what you’re *looking* at.

Twelve of the most-searched names in peptide care, each explained the same way: what it is, where the research stands, its FDA status, and what a prescription route looks like.

How to read a library page

Study summaries identify the model used. Much peptide research is in cells and animals, and a result in rats is not a result in people.

Reading the evidence

Study models, populations and preparations differ. Findings for one do not establish outcomes for another.

## All peptides
