Semax

Semax is a synthetic heptapeptide derived from adrenocorticotropic hormone (ACTH) fragment 4-10, extensively studied for its nootropic, neuroprotective, and neurorestorative properties.

Also known as: Synthetic ACTH Analog, Cognitive Enhancement Peptide

Typical Dose 300-600mcg
Storage Store as directed; keep sealed and dry
How Often 1-2 times daily

Overview

Semax is a synthetic heptapeptide derived from adrenocorticotropic hormone (ACTH) fragment 4-10, extensively studied for its nootropic, neuroprotective, and neurorestorative properties. Originally developed in Russia for stroke recovery, this brain-targeted peptide rapidly increases BDNF levels and modulates dopaminergic and serotonergic systems to enhance cognitive function, memory, and focus.

Key Benefits

  • Memory Enhancement
  • Attention and Focus
  • Learning Acceleration

Rapid brain delivery, extensive clinical research, easy self-administration, excellent bioavailability to brain regions

Mechanism of Action

Direct transport through olfactory epithelium and trigeminal nerves, bypassing blood-brain barrier for enhanced CNS penetration

Pharmacokinetics

Peak plasma concentration: 20 min. Elimination half-life: 3 min. Largely cleared by: ~15 min.

Peptide Interactions

  • NA-Semax-Amidate — Use Caution: Enhanced version of same peptide - do NOT use simultaneously. Choose one or the other based on desired duration and potency
  • Selank — Synergistic: Complementary anxiolytic effects while Semax provides cognitive enhancement
  • BPC-157 — Compatible: No known negative interactions, both support neuroplasticity through different mechanisms
  • TB-500 — Compatible: Both support brain health and recovery, can be used together for comprehensive neuroprotection
  • Stimulants — Monitor Combination: May enhance effects of stimulants - monitor carefully and reduce stimulant doses when combining
  • MAO-Inhibitors — Use Caution: Theoretical risk due to monoamine system effects - consult healthcare provider before combining

What to Expect Oral

Days 1-3: Initial cognitive clarity and focus enhancement, possible mild nasal sensation. Week 1: Improved attention span and mental stamina during demanding tasks. Week 2-3: Enhanced memory consolidation and learning capacity, stable mood effects. Week 4: Peak cognitive benefits with improved stress resilience and mental flexibility. Post-cycle: Gradual return to baseline over 3-7 days, some benefits may persist.

Side Effects & Safety

Start with lowest effective dose (300mcg) to assess individual response. Avoid concurrent use with other intranasal medications that cause vasoconstriction. Monitor for any signs of nasal irritation, bleeding, or persistent discomfort. Do not exceed 4-week continuous use periods without medical supervision. Potential to enhance effects of stimulants - reduce other stimulant doses accordingly.
