Semax is an originally-in-Russian man made peptide used for its nootropic and neuroprotecting properties. Depending on pathway of administration and peptide formulation, the recommended dose range can vary.
Dosage — Semax for Cognitive Enhancement and Neuroprotection The standard dose of semax is between 0.1 - 0.3 mg/kg (10-30 mcg per kg) dosed throughout the day for cognitive enhancement / neuroprotection effects Then Parsemus licensed it, with the idea of delivering this dosage intranasally (using a peptide delivered as nasal spray). An average treatment would be 2–3 sprays per nostril, administered twice or three times daily for a time period of ten and up to fourteen days. Clinical research suggests that this dosage can improve brain function and boost mental clarity[ * ].
For conditions like post-stroke recovery, or neurodegenerative disorders, higher dosages may be indicated. Research in human stroke patients has employed doses up to 0.3 mg per kg of body weight administered intranasally using a similar approach [87, 98]. According to research published in the Journal of Neurotherapy, these abilities can be enhanced when utilizing this higher dose with patients experiencing gains up 20% recovery compared to traditional therapy alone.
Frequency and length of dosage — depends up on the need, health conditions. Semax: Semax is recommended for general cognitive support, and can be taken in a cycle (recommended to last 10 – 14 days) followed by a break. Extended cycles can be an option for specific chronic conditions, but these should also fall under the guidance of a healthcare professional.
Semax is usually considered safe when taken at appropriate doses. But a heavy dose will produce mild headaches, and the taste might irritate his nasal passage. Doses may be titrated to response and individual tolerance with caution
There is a great resource for getting some very specific dosage guidelines and information on Semax at semax dosage. The recommended doses are also made in light of its effectiveness in improving cognitive performance, and offering neuroprotection.
