Semax N-Acetyl (NA-Semax Amidate)
Also known as: N-Acetyl Semax Amidate · NA-Semax · Semax Amidate · Modified Semax
A modified form of Semax with both N-terminal acetylation and C-terminal amidation, making it 2-3x more potent than standard Semax and more resistant to enzymatic degradation. The preferred form for cognitive enhancement due to its improved bioavailability and stability.
What is Semax N-Acetyl (NA-Semax Amidate)? A modified form of Semax with both N-terminal acetylation and C-terminal amidation, making it 2-3x more potent than standard Semax and more resistant to enzymatic degradation. The preferred form for cognitive enhancement due to its improved bioavailability and stability.
How does Semax N-Acetyl (NA-Semax Amidate) work? N-Acetyl Semax Amidate has the same mechanism as Semax (BDNF upregulation, neuroprotection, monoamine modulation) but the chemical modifications protect it from enzymatic degradation, extending its activity window and requiring lower doses for equivalent effects.
Benefits of Semax N-Acetyl (NA-Semax Amidate): 2-3x more potent than standard Semax; Longer activity due to greater enzymatic stability; Significantly upregulates BDNF (300% increases reported); Enhanced memory, focus, and neuroplasticity; More economical (lower doses effective); Neuroprotection and stroke recovery research
Semax N-Acetyl (NA-Semax Amidate) dosage: 2-3x more potent than regular Semax. Start at 100-150mcg to assess response. 300mcg equivalent to ~900mcg regular Semax.

Mechanism of Action
N-Acetyl Semax Amidate has the same mechanism as Semax (BDNF upregulation, neuroprotection, monoamine modulation) but the chemical modifications protect it from enzymatic degradation, extending its activity window and requiring lower doses for equivalent effects.
Benefits
- 2-3x more potent than standard Semax
- Longer activity due to greater enzymatic stability
- Significantly upregulates BDNF (300% increases reported)
- Enhanced memory, focus, and neuroplasticity

View all Cognitive & Nootropic peptides →Pinealon
EDR tetrapeptide
A synthetic tripeptide (Glu-Asp-Arg) from the Khavinson peptide bioregulator series targeting the brain and pineal gland. Reduces neuronal apoptosis, improves cognitive function in aging models, and normalizes circadian rhythm disruption. Distinct from Epithalon despite also targeting the pineal gland.
Cortagen
Cerebral cortex peptide bioregulator
A peptide bioregulator targeting the cerebral cortex and CNS from the Khavinson series. Normalizes cortical neuron function, reduces age-related neurodegeneration, and improves cognitive function. Particularly studied for age-associated cognitive decline, vascular dementia, and post-stroke recovery.
Noopept
GVS-111
A synthetic dipeptide nootropic approximately 1000x more potent than piracetam. Stimulates BDNF and NGF expression with significant neuroprotective and cognitive-enhancing effects.
Cerebrolysin
FPF-1070
A complex mixture of low-molecular-weight neuropeptides derived from porcine brain proteins. The only peptide-based nootropic with robust clinical evidence for Alzheimer disease and brain injury.
