Update
We were filing nootropics under anti-aging. They have their own page now.
Thirteen compounds sat in the longevity category because there was nowhere else to put them. A third of that page was not about ageing, which made both groups less useful.
Until this week, semax, selank, noopept, bromantane, dihexa, cerebrolysin, P21 and six others were categorised on this site as anti-aging and longevity. Not because anyone argued they belonged there. Because the site had five categories and none of the other four fitted, and a compound with no category does not appear when somebody browses.
That is a bad reason, and it had a visible cost. The anti-aging page listed fifty-two compounds, of which roughly a third were cognitive or mood compounds with no claim to slow anything. Its own introduction described NAD+, the mitochondrial peptides and the Khavinson bioregulators — three lines of work that are genuinely about ageing — while the grid underneath opened with growth hormone secretagogues and carried a dozen nootropics. A reader arriving from a search for longevity compounds had to sort our filing before they could start.
There is now a sixth category, cognition and mood, and those thirteen have moved into it. Anti-aging and longevity is thirty-nine compounds that share a subject, and its introduction names all four lines of work its grid actually contains rather than three of them.
The new page is not a friendlier home for the same claims. It is the hardest category on this site to read honestly, and it says so. The outcome is subjective, the placebo response for anything sold as a cognitive enhancer is large and well documented, and much of the literature is Russian-language, small, and unreplicated outside the country where these are registered medicines. Semax and selank have real regulatory approval in Russia and none anywhere else, and both halves of that belong in the same sentence.
Nothing broke in the move. Every existing link still resolves, and each compound's breadcrumb now says where it actually sits — which for Adalank, the listing that prompted somebody to ask, is cognition and mood rather than longevity.
The general point, since this is the second time we have written it: a category on this site describes how people search, not what a compound does. When the two drift apart the category is the thing that should change.

This page is educational. It describes what published research reports, not what you should do. Peptides discussed here are largely not approved for human use, and nothing on Bioalmanac is medical advice.
