Adamax

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.

Not FDA-approved - research chemical

Quick answer

How it works

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.

Source: Parent compound: Semax. Adamax: no indexed human PK as of 2026.

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.

Dose numbers on vendor pages are not citations.

Verdict

Adamax is a vendor conjugate. Adamantane is real chemistry. Semax papers are not this molecule’s papers.

Interactions & Contraindications

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

Adamax vs. Semax

Canonical comparison: Adamax vs Semax

Attribute	Adamax	Semax
Structure	Adamantane-Semax (vendor)	ACTH 4–10 heptapeptide
Human PK	None indexed	Russian clinical literature
Evidence level	Low	Low–moderate (parent drug in Russia)

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