What is Semax?The science, simply
Semax is a lab-made copy of a short piece of ACTH, a hormone your body makes. You take it as a nasal spray.
In rats, one nasal dose raised BDNF, a growth factor that helps brain cells connect.1
In 24 healthy adults, one dose changed resting brain activity within minutes.2
Human studies are small and mostly from Russia. No large trials have tested Semax for focus or memory, so results aren’t guaranteed. 1 Dolotov 2006, Brain Research. 2 Lebedeva 2018, Bull Exp Biol Med.
Is Semax for me?Brain fog, focus, staying sharp
- Brain fog by mid-afternoon
- Losing your train of thought

- Want to stay sharp as you age
Lots of things cause these. A clinician looks at what’s behind yours and whether Semax fits. It isn’t proven to fix them.
Straight answers10 quick questions
What is Semax?
Semax is a lab-made peptide based on a short piece of ACTH, a hormone your body makes. It was developed in Russia and is taken as a nasal spray.
What does Semax do?
It is being studied for how it affects BDNF, a growth factor that helps brain cells connect. Most of the research is in animals or small Russian studies, so results in people aren’t proven or guaranteed.
Is Semax safe?
FDA says there is not enough human data to describe Semax’s safety, and long-term safety has not been studied. A licensed clinician reviews your health history first. See the safety information below.
Is Semax FDA approved?
No. Semax is not FDA-approved, and FDA does not review compounded drugs for safety or effectiveness. In July 2026 an FDA advisory committee voted 8-5 to recommend it for compounding, and on October 30, 2026 HHS said it won’t take enforcement action against licensed pharmacies that compound nasal spray Semax while FDA rulemaking continues. That policy is not an approval.
Is Semax legal in the US?
Sommar Club offers Semax by prescription only. Compounded Semax nasal spray is prescribed under an HHS enforcement discretion policy for licensed pharmacies, published October 30, 2026, while FDA rulemaking continues. That policy is not an approval and HHS may revisit it.
How do you take Semax?
As a nasal spray. Your clinician sets your dose and schedule based on your health history. Follow the directions that come with your prescription.
How long does Semax take to work?
It varies, and results aren’t guaranteed. In one small study, a single dose changed resting brain activity within minutes. That is not the same as feeling a difference.
Is Semax a stimulant?
No. Semax is a peptide, not a stimulant. Tell your clinician if you take stimulants, including ADHD medicines.
How much is Semax?
$149 a month, or $119 a month on the 6-month plan ($714 billed upfront). Clinician review and shipping are included.
