Listen
The Peter Attia Drive
Episode 403, "Peptides: separating scientific promise from marketing hype" (Aug 2026, 53 min). Good for a five-question test you can use on any compound.
Huberman Lab
"Peptides: The Science, Uses and Safety" with Dr. Abud Bakri (June 2026), plus the 2024 solo episode on benefits and risks. Good for a long walk through the main types.
The Guardian's Science Weekly
"What's behind the injectable peptide craze?" (March 2026, 18 min). Good for a short, neutral start, with a peptide researcher from Imperial College London.

Read
"The Peptide Craze" by Eric Topol
A free essay from a Scripps Research cardiologist. Good for the skeptical case, laid out compound by compound.

A 160-page primer written for physicians (2020). Good for the cell biology behind peptides.
Peptide Chemistry and Drug Design, edited by Ben Dunn
A university textbook. Good if you want the real chemistry of how peptide drugs get made.

Not about peptides. Good for learning how to weigh risk and proof for anything you put in your body.
Look things up
Examine
A large independent database on supplements and nootropics. Good for anything that is not a peptide.
FDA: compounding safety list
The FDA's own list of substances it says may be risky to compound. It gives the FDA's safety concerns for each. BPC-157, CJC-1295, TB-500, Semax and Selank now sit in its "nominated but withdrawn" table: they used to be in the risky group, and the people who nominated them pulled the request. Good for the regulator's side.
ClinicalTrials.gov
The public register of human trials. Good for one question: has anyone tested this in people, and did they post results?
NIH Office of Dietary Supplements
Plain fact sheets on vitamins, minerals and common supplements. Good for what studies tested and known side effects.
Cochrane
Reviews that pool every good trial on a question, each with a plain-language summary. Good for seeing the whole picture, not one study.
WADA Prohibited List
What is banned in tested sport for 2026. Section S2 covers peptide hormones and growth factors. Good if you compete.
PubMed
The US government's free index of medical studies. Good for checking any claim at the source.
