Semax
Nootropic: focus, memory, neuroprotection.
iThe essentials in 10 seconds
- Nootropic derived from ACTH (4-10): acts on the brain
- Improves focus, working memory and mental clarity
- Studied neuroprotective and anti-stress effect
- Intranasal or subcutaneous administration depending on the form
IWhat is Semax?
Semax is a peptide derived from a fragment of ACTH (4-10), with no adrenal hormonal action. It increases neurotrophic factors (BDNF) and cerebral circulation, improving mental clarity, attention and working memory. It also has neuroprotective and anti-stress properties.
Nootropic often used off-label. Data mainly Russian and preclinical; supervised use recommended, to be avoided in case of unevaluated neurological disorders.
The molecules presented on this site are innovative and fall under experimental use. Human data remain limited: a studied mechanism or a preclinical observation is not sufficient to demonstrate a benefit. The regulatory status in Morocco is not established for most of these peptides. Any use is decided within the framework of a medical consultation, with follow-up — never alone, never without an assessment.
IIThe benefits
Improves concentration and mental clarity on demanding tasks.
Supports learning and working memory.
Neuroprotective action (neurotrophic factors) studied in several models.
Anti-stress and anti-mental fatigue properties.
Reduces the feeling of brain fog and cognitive fatigue.
Support option after neurological stress (medical supervision).
IIIRecommendations & how to use
Route: intranasal (drops/spray) or subcutaneous depending on the form · Timing: in the morning or before a demanding task (avoid after 5 p.m.) · Storage: refrigerated (2–8 °C).
May interact with psychotropic treatments: must be reported.

IVThe two protocols
Goal: improve attention, working memory and mental clarity.
Monitoring: mental clarity, attention, tolerance.
Goal: support the mind during periods of overload or cognitive fatigue.
Combine with: sufficient sleep, breaks, workload management.
VProtocol rules
- Take in the morning (stimulating effect)
- Sufficient sleep (foundation of the brain)
- Note clarity, focus and tolerance
- Store vials in the refrigerator
- Report any psychotropic treatment
- No self-use without medical advice
- Do not take in the evening (possible insomnia)
- Do not chain courses without a break
- Unevaluated neurological disorders: medical advice
- Pregnancy, breastfeeding: medical advice
