What is Semax?
Semax is a seven amino acid synthetic peptide developed at a Russian institute in the 1980s, built from a fragment of ACTH, the hormone the brain uses to signal the adrenal glands. It appears to raise brain-derived neurotrophic factor, a growth signal for neurons, which is why it is used for focus and mental energy. Here it is prescribed after a free consultation and a review of your history.
Semax benefits and uses.
-
Focus and mental energy
Animal work on learning and attention is the source of the focus claims; cognitive testing in people has not been published.
-
Recovery after stroke
Russian human studies of 110 people looked at recovery after stroke, using comparison groups.
-
A brain growth signal
A post-stroke study tracked BDNF, the neuron growth signal semax appears to raise.
-
Optic nerve health
Human studies have looked at semax in certain optic nerve conditions.
- 7amino acids, built from a fragment of ACTH
- 187people in its largest tolerability study
- 8-5FDA advisory committee vote to recommend it for compounding, July 2026
How does Semax work?
Semax appears to raise brain-derived neurotrophic factor, a growth and survival signal for neurons. It also appears to influence genes involved in the brain's response to low oxygen and inflammation, which is why the human research is in stroke recovery and optic nerve conditions. Most of this rests on animal and lab work, plus a small number of human imaging studies.

Common questions.
What is semax?
Semax is a seven amino acid peptide built from a fragment of ACTH, developed in Russia, where it is used for stroke and some optic nerve conditions.
What does semax do?
It appears to raise BDNF, a growth signal for neurons. Its human research is in stroke recovery and optic nerve conditions; its effect on focus and memory comes from animal work and has not been tested on cognitive tests in people.
Is semax safe?
As a nasal spray, small studies reported it as tolerated, with nasal irritation the main finding. There is no long-term or injection safety data.
Is semax FDA approved?
No. In July 2026 an FDA advisory committee voted 8 to 5 to recommend allowing it to be compounded, for stroke, migraine, and trigeminal neuralgia. FDA has not issued a final rule.
How is semax taken?
In its studies it was used as a nasal spray. How you take it and on what schedule is set by Catherine Seidle, APRN at your visit.
How much does semax cost?
A take-home vial is $180. The consultation is free, and any visit or labs your plan needs are quoted before you start.
Semax vs selank: what is the difference?
Semax is built on a fragment of ACTH and studied for stroke recovery; selank is built on an immune peptide and studied for anxiety. Semax is usually chosen for focus and selank for calm.
