By what it is for
Most people arrive here with a goal rather than a compound name. Each group states what the evidence supports and what it does not, and lists everything we have a cited profile for.
Weight loss
20 compoundsGLP-1 agonists and the dual and triple agonists that followed them. The best-evidenced group on this site, and the one most often sold as something it is not.
Muscle & performance
25 compoundsGrowth hormone secretagogues, GHRH analogues and the growth factors downstream of them. Evidence quality varies more inside this group than in any other on the site.
Healing & recovery
15 compoundsBPC-157, TB-500 and the rest of the repair compounds. The most-discussed category online and the least-evidenced one here, which is worth saying in the first line, not the footnotes.
Anti-aging & longevity
39 compoundsThe growth hormone secretagogues, NAD+ and the mitochondrial peptides, and the bioregulators. The category with the deepest measurement problem: almost nothing here has been tested against an outcome anyone actually cares about.
Cognition & mood
13 compoundsThe nootropics and neuropeptides — semax, selank, noopept and the rest. Almost all of it is Russian-language literature, and almost none of it has been replicated anywhere else.
Skin & hair
10 compoundsCopper peptides, the neurotransmitter-blocking cosmetics, and the melanocortins. The category splits along a line that matters more than the compounds do.
A compound can sit in more than one group, so the counts add up to more than the catalogue. Grouping is ours and describes what a compound is studied for — it is not a claim that it works.
