Not approved for human use

A regulatory status describes paperwork, not safety. An approved compound can still be wrong for a given person, and an unapproved one is neither thereby dangerous nor thereby fine.

Common questions

Semax, answered plainly.

01What is Semax?+

A synthetic heptapeptide analog of the ACTH(4-10) fragment, studied as a neuroprotective and nootropic compound. Reported mechanisms include upregulation of neurotrophins (BDNF and NGF) and interaction with melanocortin and enkephalin systems. It is listed here under Cognitive / Longevity as educational reference, which is not a recommendation to use it.

02Is Semax FDA approved?+

Research only. This substance is sold and handled as a research material and is not approved for human use. There is no approved label, which means there is no agency-reviewed information about how it should be handled, who should avoid it, or what happens alongside other medicines.

03What is the half-life of Semax?+

Minutes in plasma (~2-5 min); intranasal or subcutaneous. A half-life is an educational pharmacology figure describing how long the body takes to clear half of a substance. It is not a schedule and does not imply one.

04How is Semax stored and handled?+

Lyophilized powder kept frozen or refrigerated and protected from light; reconstituted or nasal solutions refrigerated, used within a limited window. Storage conditions come from a manufacturer's own label where one exists, and a compound with no approved label has no agency-reviewed handling instructions at all.

05What vial strengths of Semax are commonly sold?+

Commonly listed vial strengths are 5, 10, 30 mg. A vial strength is a market fact about how a product is packaged. It is not a dose, and it says nothing about how much of anything belongs in any person.
