Methylene Blue is a synthetic phenothiazine dye studied as a mitochondrial enhancer and nootropic, acting as an alternative electron carrier in the respiratory chain. Note: Methylene blue is a small-molecule redox dye, not a peptide, though suppliers often stock it alongside peptides.
9-Me-BC (9-methyl-beta-carboline) is a small-molecule beta-carboline studied as a nootropic for its dopaminergic, neuroprotective, and neurogenesis-promoting effects in animal models.
Adalank is a short synthetic regulatory peptide in the Selank/Tuftsin-related family, studied for anxiolytic and cognition-supporting properties.
Adamax is a proprietary nootropic peptide product marketed for cognitive enhancement and neuroprotection. It is sold as a research chemical with limited public pharmacological data.
Actogenix is a proprietary peptide-bioregulator-style product marketed for vitality, energy, and healthy-aging support. It is sold as a research chemical with limited published data.
Bromantane is an adamantane-derived actoprotector with mild stimulant and anxiolytic properties, used clinically in Russia (as Ladasten) for asthenia and fatigue. It is a small-molecule research chemical, not a peptide, in most other markets. Note: Bromantane is a small-molecule actoprotector, not a peptide, though it is often catalogued with research peptides.
Cortexin is a polypeptide complex extracted from cerebral cortex tissue, used clinically in Russia and several other countries as a neuroprotective and nootropic agent. In Western markets it is sold as a research chemical. (Cortexin is a registered polypeptide drug in some countries; presented here for educational/research reference only, not as medical guidance.)
DNSP-11 is an 11-amino-acid peptide derived from the proGDNF (glial cell line-derived neurotrophic factor) precursor that is being studied for its neuroprotective and neurorestorative effects on dopaminergic neurons.
Colivelin is a synthetic hybrid neuroprotective peptide that fuses activity-dependent neurotrophic factor (ADNF) with a potent Humanin derivative, studied for protecting neurons against amyloid-beta and other neurotoxic insults.
A research blend of two stabilized Russian-developed neuropeptides: N-Acetyl Semax (a nootropic ACTH fragment) and N-Acetyl Selank (an anxiolytic tuftsin analog). The combination is studied for cognition, focus, and stress modulation.
N-Acetyl Selank Amidate is a stabilized analog of the anxiolytic peptide Selank, modified for improved durability and intranasal delivery. It is studied for anxiety reduction and cognitive support.
N-Acetyl Semax Amidate is a stabilized analog of the ACTH(4-10)-derived nootropic peptide Semax, modified for durability and intranasal use. It is studied for cognition, focus, and neuroprotection.
NAD+ is an essential coenzyme central to cellular energy production and DNA repair whose levels decline with age. It is studied and supplemented for longevity, mitochondrial function, and metabolic health. Note: NAD+ is a coenzyme, not a peptide, commonly sold alongside longevity research compounds.
P21 (P021) is a small peptidergic compound derived from the active region of ciliary neurotrophic factor, studied for promoting neurogenesis and synaptic plasticity. It is researched preclinically as a neuroprotective and cognition-enhancing agent.
Tesofensine is a triple monoamine reuptake inhibitor originally developed for neurodegenerative disease and later investigated as an anti-obesity drug. It produces appetite suppression and notable weight loss in clinical trials. Note: Tesofensine is a small-molecule triple monoamine reuptake inhibitor, not a peptide, but is sold alongside metabolic research compounds.
TRH (protirelin) is the tripeptide hypothalamic hormone that triggers pituitary release of TSH and prolactin. It is also studied for neurostimulant, arousal, and mood-related central nervous system effects.
MIF-1 (Pro-Leu-Gly-NH2) is a hypothalamic tripeptide studied for dopaminergic modulation and antidepressant-like effects. It is also known historically as melanocyte-inhibiting factor.
A synthetic dipeptide-derived nootropic developed in Russia, structurally related to the racetam family. It is studied for memory, learning and neuroprotective effects at very low milligram doses.
A 33-amino-acid neuropeptide produced in the lateral hypothalamus that regulates wakefulness, arousal, appetite and energy homeostasis. It is studied for its powerful promotion of alertness and sleep-wake stability.
A 28-amino-acid hypothalamic neuropeptide that, alongside Orexin A, regulates arousal, wakefulness and feeding. It shows relative selectivity for the OX2R receptor subtype.
A heptapeptide consisting of the ACTH 4-7 fragment extended with a Pro-Gly-Pro tail, better known as the peptide Semax. It is studied as a nootropic and neuroprotective agent.
A synthetic peptide comprising the first 24-34 N-terminal residues of adrenocorticotropic hormone (tetracosactide/cosyntropin family), which retains full corticotropic activity. It is used clinically to stimulate adrenal cortisol production and diagnostically to test adrenal function.
A research peptide related to delta sleep-inducing peptide (DSIP) chemistry, marketed for its potential effects on sleep regulation and stress modulation. Human data are minimal and it remains an investigational research compound.
A nonapeptide oxytocin variant referring to the nine-amino-acid oxytocin sequence, studied for its roles in bonding, mood, social behavior and reproductive physiology. It is sold as a research-grade analog of native oxytocin.
Melatonin is the body's primary circadian hormone, secreted by the pineal gland to signal darkness and regulate sleep timing. It is widely studied as a chronobiotic and antioxidant research compound. Note: Melatonin is a small-molecule hormone, not a peptide, though it appears in some research-compound catalogs.
A4 Amyloid Beta refers to the amyloid-beta peptide derived from the amyloid precursor protein and central to Alzheimer's disease research. It is used purely as a research reagent for neurodegeneration studies. This is a neurotoxic laboratory reagent intended strictly for in-vitro research; it is not for administration.
