About
Clarity in peptide and longevity science.
PeptideCrux gathers published research on peptides and longevity into one searchable index. Each record summarises mechanisms, regulatory status and the quality of the evidence, and links straight to the original studies so you can read them yourself.
Our principles
Sources first
Every compound and claim links to peer-reviewed literature, mostly via PubMed. We never invent citations.
Graded by design
Evidence tiers describe how a study was done, from cell culture to approved drug. They are not safety ratings or endorsements.
Honest uncertainty
Where data is thin, disputed or only preclinical, we say so directly in the record.
Education only
PeptideCrux is not medical advice and never gives dosing or sourcing guidance.
What you can do here
Browse the index, compare compounds side by side, explore mechanisms in 3D, model chemical mixes and stacks, or sketch new sequences with the AI designer. All tools are for research and education.
