How this site works
Most people arrive with a goal, not a compound. Each page below starts from the goal, maps the library compounds people reach for, grades the evidence behind each one, and gives you a way to choose between them, including saying plainly where the honest answer is that no compound in this library has real human evidence for that goal. Every claim links to the published study behind it. Nothing here is for sale.

A research reference for the compounds mapped to longevity and healthy aging. It sets out what the randomized human trials of oral NAD+ precursors and DHEA actually measured, why the injected forms have no outcomes evidence at all, and where the rest is mice and cell culture.

An honest map of a goal this library cannot serve. No compound reviewed on this site has human evidence of improving cognition, and the three that were tested against a cognitive endpoint each returned a null result.
3 compounds mapped · Last reviewed August 3, 2026
A research reference for the compounds mapped to aerobic capacity and stamina. Every one of them is prohibited in tested sport at all times, and only one has a randomized human trial using an endurance endpoint.
4 compounds mapped · Last reviewed August 3, 2026
A research reference for the peptides mapped to gut healing and intestinal repair. It covers what the rodent colitis literature established, why almost none of it has been tested in people, and what "healing the gut lining" does and does not mean in the published record.

A research reference for the compounds people map to hair loss and hair growth, including the finding that the copper-peptide hair study everyone cites tested a different peptide, and that nothing in this library has a published human efficacy result for hair.

A research reference for the peptides mapped to injury recovery and tissue repair, covering what the animal literature established, what the handful of human trials actually measured, and how to tell the two apart.
4 compounds mapped · Last reviewed August 3, 2026
A research reference for the compounds mapped to sexual desire and sexual function, one of them FDA-approved with a labeled contraindication, one carrying the largest randomized literature in this library, and one whose approved use is local rather than systemic.
3 compounds mapped · Last reviewed August 3, 2026
A research reference for the incretin compounds mapped to weight loss, covering what the registrational trials measured, what happens when treatment stops, what the body-composition data show, and which parts of the picture come from a label rather than from a trial.
