Selank
ResearchCognitiveA heptapeptide analog of the immunomodulator Tuftsin, developed by the Russian Institute of Molecular Genetics. Provides profound anxiety reduction with enhanced mental clarity, without sedation or addiction risk.
Semax
ResearchCognitiveA neuro-stimulatory heptapeptide derived from ACTH, rigorously validated as a nootropic. Enhances focus, accelerates problem-solving, and provides neuroprotection against oxidative damage.
Dihexa
ResearchCognitiveA synthetic angiotensin IV analog with synaptic formation potency 10 million times stronger than BDNF. The ultimate heavyweight nootropic for cognitive enhancement.
N-Acetyl Selank Amidate
ResearchCognitiveA chemically stabilized variant of Selank with dramatically longer half-life and deeper blood-brain barrier penetration for enhanced anxiolytic and cognitive effects.
P21
ResearchCognitiveA neurogenic peptide derived from CNTF that promotes hippocampal neurogenesis and clears amyloid plaques, targeting Alzheimer's and TBI recovery.
PE-22-28
ResearchCognitiveA spadin analog studied for rapid antidepressant-like effects, working through TREK-1 potassium channel modulation.
Pinealon
ResearchBioregulatorA Khavinson tripeptide bioregulator for brain cortex modulation, circadian rhythm restoration, and neuroprotection against oxidative aging.
Cortagen
ResearchBioregulatorA tetrapeptide bioregulator for cerebral cortex modulation, used in neuro-recovery protocols after stroke and cognitive decay.
Cerluten
ResearchBioregulatorA Cytomax neuro-restorative complex from cerebral cortex tissue for cognitive decline reversal and CNS stress recovery.
