Peptides 101: What Are Peptides and How Do They Work?
The foundational guide — what peptides actually are at a molecular level, how they signal to cells, and the major clinical uses across recovery, performance, and longevity.
AEON Journal
Evidence-based insights from the frontiers of peptide therapy, healthspan research, and clinical performance. Start with our foundational six-part series on peptides.
The foundational guide — what peptides actually are at a molecular level, how they signal to cells, and the major clinical uses across recovery, performance, and longevity.
Eight functional categories mapped out, from BPC-157 and TB-500 through GH-releasing peptides, GLP-1 agonists, cognitive peptides, and the longevity frontier.
The 12 biggest misconceptions about peptide therapy — that they are steroids, miracle drugs, illegal, or untested — corrected with the actual evidence.
Evidence-backed effects on recovery, body composition, sleep, cognition, skin, and longevity — with honest notes on what the data actually supports.
Epitalon, Thymalin, MOTS-c, FOXO4-DRI, and the senolytic peptides driving the next wave of anti-aging research — mechanisms, evidence, and practical protocols.
A complete beginner's guide to sourcing, reconstitution, injection technique, dosing, cycling, and protocol design — the ten-step framework we recommend.
