How Adamax works

Adamax upregulates BDNF expression and promotes neurotrophin signaling through melanocortin receptor pathways, similar to Semax but with increased potency due to the adamantyl modification improving lipophilicity and BBB permeability. It may also influence dopaminergic and serotonergic tone in prefrontal regions relevant to focus and mood. Human clinical data is absent and all evidence is derived from animal and in vitro models.

Cerebrolysin

Moderate evidence

Nootropic

Cerebrolysin is a standardized mixture of neuropeptides and amino acids derived from porcine brain tissue that is used clinically in some European and Asian countries for cognitive impairment, stroke rehabilitation, and neurodegenerative disorders. It contains low-molecular-weight peptides that can cross the blood-brain barrier.

P21

Animal studies only

Nootropic

P21 is a tetrapeptide derived from the ciliary neurotrophic factor (CNTF) binding interface, studied in animal models for neurogenesis stimulation, memory enhancement, and potential Alzheimer's disease prevention. It has shown the ability to increase BDNF levels and reduce tau hyperphosphorylation in rodent models.

PE-22-28

Preliminary evidence

Nootropic

PE-22-28 is a synthetic hexapeptide analog of spadin, itself derived from the propeptide of sortilin, studied as an antidepressant and cognitive enhancer that targets TREK-1 potassium channels in the CNS. Animal studies suggest rapid antidepressant-like effects and potential cognitive benefits.

Pinealon

Preliminary evidence

Nootropic

Pinealon is a synthetic tripeptide (Glu-Asp-Arg) derived from the pineal gland, studied for neuroprotective effects, circadian rhythm regulation, and cognitive performance in animal models and limited clinical observations in Eastern European research. It is related to the family of short peptide bioregulators developed by the St. Petersburg Institute of Bioregulation.
