Semax
Semax Heptapeptide
A synthetic peptide analog of ACTH(4-7) developed in Russia for cognitive enhancement, neuroprotection, and stroke recovery. Promotes BDNF and NGF expression.
How Semax Works
Semax is a synthetic analogue of the adrenocorticotropic hormone (ACTH) fragment 4-10, with an added Pro-Gly-Pro C-terminal tripeptide for metabolic stability. It acts as a potent nootropic by significantly upregulating brain-derived neurotrophic factor (BDNF) and nerve growth factor (NGF), promoting neuronal survival, synaptic plasticity, and neurogenesis. Unlike full-length ACTH, Semax does not stimulate adrenal cortisol production, allowing it to enhance cognition and neuroprotection without stress hormone elevation.
📊 Evidence by Outcome
Enhances BDNF expression and cognitive performance. Approved in Russia for cerebrovascular disorders.

Side Effects & Safety
Interactions & Contraindications
Drug Interactions
- •May interact with stimulant medications (additive effect on alertness and focus)
- •Potential interaction with MAO inhibitors (Semax influences monoamine neurotransmitter systems)
- •Caution with thyroid medications (Semax is an ACTH analogue and may affect the HPA axis)
Supplement Interactions
- •Synergistic with Selank for combined focus + calm effects
- •Compatible with racetams and other nootropics
- •May complement alpha-GPC or citicoline for enhanced cognitive effects
Food & Timing
- •Intranasal form not significantly affected by food
- •Best used in the morning or early afternoon to avoid sleep disruption
- •No known food interactions
Who Should Avoid
- •Pregnancy and breastfeeding
- •Children under 18
- •Individuals with acute psychosis or severe anxiety disorders (may overstimulate)
- •History of seizure disorders (BDNF elevation may theoretically lower seizure threshold in susceptible individuals)

Frequently Asked Questions
Semax can be obtained through peptide-specialized clinics and compounding pharmacies in the UAE. It is approved as a drug in Russia but not in the GCC region. Availability is niche but growing as peptide clinics expand.
Cognitive effects (improved focus, mental clarity) are often noticed within 15-30 minutes of intranasal dosing. Neuroprotective and longer-term cognitive benefits develop over 2-4 weeks of consistent use.
No. Although Semax is derived from ACTH, the specific fragment used (4-10) and the structural modifications eliminate the cortisol-stimulating properties. It provides the neurotropic benefits of ACTH without activating the adrenal glands.
Yes, Semax is commonly used daily in cycles of 10-20 days on, followed by a 10-day break. Some users dose continuously. Russian clinical protocols typically recommend 10-14 day courses with breaks between.
