Semax is a synthetic peptide researched for its effects on neuroprotection and cognitive function, shipped same business day from Melbourne with free express shipping on orders over $200.

What Is Semax?

Semax is derived from a fragment of adrenocorticotropic hormone (ACTH), engineered to retain the cognitive and neuroprotective effects of ACTH while eliminating its hormonal activity. Semax has been extensively studied for over 30 years and is widely regarded as one of the most well-documented nootropic peptides.

Semax is listed on Russia's List of Vital & Essential Drugs and has been approved there for the treatment of stroke, cognitive disorders, optic nerve disease, and as a general nootropic. It has demonstrated an excellent safety profile with no reported tolerance, dependence, or withdrawal, even with extended use.

How Does Semax Work?

Semax enhances cognitive function and neuroprotection through multiple neurotransmitter and neurotrophic pathways:

Where Selank (its sister peptide from the same research program) is primarily an anxiolytic that works through GABA modulation, Semax is primarily a nootropic and neuroprotectant that works through BDNF upregulation and monoamine activation, making them complementary rather than interchangeable.

Research Focus Areas

Semax is being studied for its potential effects on:

• Cognitive enhancement — memory, learning, attention, and mental clarity
• Neuroprotection — neuronal survival and recovery following ischemic injury
• Stroke recovery — improved functional independence and motor performance in clinical trials
• BDNF elevation — rapid upregulation of brain-derived neurotrophic factor
• Mood and stress — antidepressant-like effects and stress adaptation
• Optic nerve support — improvements in visual acuity in optic neuropathy models
• Antioxidant activity — protection against copper cytotoxicity and heavy metal-induced damage
• ADHD symptoms — attention and executive function improvements

In a clinical trial with 110 stroke patients, intranasal Semax increased plasma BDNF levels and led to improved motor performance and functional independence. In healthy subjects, a single dose improved memory test accuracy from 41% to 71% compared to controls.
