Selank N-Acetyl (NA-Selank Amidate)
Also known as: N-Acetyl Selank Amidate · NA-Selank · Selank Amidate
An enhanced form of Selank with N-acetyl and C-terminal amide modifications that increase potency and stability. Approximately 2x more potent than standard Selank with longer duration of action.
What is Selank N-Acetyl (NA-Selank Amidate)? An enhanced form of Selank with N-acetyl and C-terminal amide modifications that increase potency and stability. Approximately 2x more potent than standard Selank with longer duration of action.
How does Selank N-Acetyl (NA-Selank Amidate) work? Same mechanism as Selank (GABAergic, serotonergic, immunomodulatory) but with improved stability against proteolytic enzymes. The modifications extend the anxiolytic and cognitive effects while requiring half the dose.
Benefits of Selank N-Acetyl (NA-Selank Amidate): Approximately 2x more potent than standard Selank; Stronger and longer-lasting anxiolytic effect; Better cognitive enhancement than standard Selank; Improved mood stability; Non-sedating, non-addictive anxiolytic
Selank N-Acetyl (NA-Selank Amidate) dosage: 2x more potent than regular Selank. 250mcg equivalent to ~500mcg regular Selank.

More Cognitive & Nootropic Peptides
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.
