Semax: How It Works, What It's Studied For & Safety
Semax is a short heptapeptide derived from a fragment of ACTH (4-7), studied in Russian neuroscience research for nootropic and neuroprotective effects. Clinicians consider it for cognitive performance and mental fatigue research. Not FDA-approved; dispensed by Wells Pharmacy Network only after a clinician evaluation.
Also known as: MEHFPGP, ACTH (4-7) PGP analog
How does Semax work?
Semax is studied for upregulation of brain-derived neurotrophic factor (BDNF) and modulation of dopamine, serotonin, and acetylcholine signaling. Its parent fragment lacks the corticotropic activity of full-length ACTH.
What is Semax studied for?
- Cognitive performance and mental fatigue research
- Stroke rehabilitation (registered as a medication in Russia for ischemic stroke)
- Mood and stress-axis research
How is Semax taken?
Most commonly compounded as a nasal spray for direct nasal-mucosa absorption; also available as a subcutaneous injection in some clinician protocols.
Is Semax FDA-approved? Is it safe?
Not FDA-approved for the prevention, treatment, or cure of any condition. Used inside research-informed, clinician-directed protocols only. Approved as a medication in Russia for specific neurological indications; that approval does not transfer to the US. Compounded prescription-only preparations are dispensed by Wells Pharmacy Network. Eligibility is decided by a licensed clinician based on intake and labs, not by checkout.
