Buy Semax (Synthetic Heptapeptide) in Canada from Legacy Laboratories. Semax is a neuroprotective peptide researched for enhancing cognitive function, neuroplasticity, and protecting against neurodegeneration.
What Is Semax?
Semax is a synthetic analog of the human adrenocorticotropic hormone (ACTH). It is highly researched for its ability to cross the blood-brain barrier and act directly on the central nervous system.
How Semax Works
Semax works by modulating the expression of Brain-Derived Neurotrophic Factor (BDNF) and Nerve Growth Factor (NGF). This mechanism supports neurogenesis, enhances synaptic plasticity, and protects neurons from oxidative stress and metabolic dysfunction.
Research & Potential Benefits
- Enhancement of cognitive functions such as memory, attention, and learning
- Promotion of neuroplasticity and neurogenesis via BDNF upregulation
- Neuroprotective effects against age-related cognitive decline
- Research interest in treating various forms of cognitive impairment
