Adamantane-Semax · Adamantyl-Semax

Adamantane-modified Semax analog sold as a nasal research spray. Search volume is real; dedicated papers are essentially absent. Treat every half-life and dose number as vendor folklore unless a citation appears. Parent Semax evidence does not automatically transfer to an adamantyl conjugate.

Mechanism of Action

Adamax is marketed as adamantane-conjugated Semax. Adamantane is a real lipophilicity/stability trick in medicinal chemistry. Transferring Semax’s BDNF papers onto this conjugate without PK is a category error.

We list it because people search it and vendors sell it. Half-life on this page is explicitly unknown.

No published human PK

Dose and duration numbers on vendor pages are not citations. If you need evidence, read Semax and treat this as an uncharacterized analog.

Safety & Considerations

Unknown human safety file. Nasal irritation possible. Adamantane moieties have their own CNS/renal baggage in other drugs — not characterized here.

Adamax vs. Semax

StructureAdamantane-Semax (vendor)ACTH 4–10 heptapeptide

Verdict: Adamax is a search term and a SKU. Semax is the molecule with papers. Do not copy Semax onset onto Adamax.

Does Adamax last longer than Semax?▼
That is the sales pitch. It is not a published human half-life.
