Bromantane vs N-Acetyl Semax Amidate
Both are discussed for cognition & mood. What this site records about each, side by side. Every figure is on the compound's own page with the source it came from.
| Bromantane | N-Acetyl Semax Amidate | |
|---|---|---|
| What it is | A Russian anti-asthenic drug, and a documented doping agent. It produced a positive test at the 1996 Olympics and is prohibited by WADA. | Semax with both ends chemically capped so it lasts longer. More potent per milligram in animal work, and no human trial of the modified version exists. |
| EvidenceHow much human evidence exists, not how well it works. | Approved for another indication | Preclinical |
| Regulatory statusReviewed 2026-08-18 | Registered in Russia as Ladasten for asthenic conditions. Not approved in the United States or the European Union, and prohibited in sport by the World Anti-Doping Agency following positive tests at the 1996 Olympics. | Not approved anywhere. Semax itself is registered in Russia; this modified version is not, and has never been through a human trial. Sold only as a research chemical. |

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. Nothing here ranks these two against each other. A table can show that one has more human evidence behind it or costs less per milligram; neither of those is a recommendation, and the right comparison for any person is one their doctor makes with them.
