Full-length adrenocorticotropic hormone peptide used in endocrine and stress-axis research; parent pathway for several nootropic ACTH analogs.

Designer Semax analog featuring terminal modifications (acetylation ± adamantane-related) intended to improve stability and BBB penetration; almost no independent peer-reviewed identity.

Non-hematopoietic EPO-derived peptide studied for neuropathy and tissue-protective inflammation control.

Khavinson tetrapeptide bioregulator (Ala-Glu-Asp-Pro) developed as a cerebral-cortex-targeted short peptide for neuroprotection and cortical gene regulation research.

Extremely potent natural mu-opioid heptapeptide from South American frog skin; research and forensic interest due to analgesic potency far exceeding morphine.

Potent procognitive angiotensin IV–related compound; extremely experimental with safety unknowns.

Mitochondrial-derived peptide studied for cytoprotection, metabolism, and neuroprotection.

Endogenous 28-amino-acid lateral-hypothalamic neuropeptide that preferentially activates OX2R to stabilize wakefulness, appetite, and arousal circuits.

Endogenous nonapeptide hormone for labor/lactation; researched for social bonding, anxiety, and intimacy.

Orally bioavailable CNTF-derived tetrapeptide (adamantylated) that enhances BDNF signaling, neurogenesis, and reduces tau/Aβ pathology in Alzheimer's mouse models.

Synthetic heptapeptide optimized from the natural sortilin-derived peptide spadin. Potent selective inhibitor of the TREK-1 (KCNK2) two-pore-domain potassium channel with preclinical antidepressant and neuroplasticity signals.

Short bioregulator peptide from the Khavinson group aimed at brain and pineal support.

Russian anxiolytic peptide analog of tuftsin; used for anxiety and cognitive stability without classic benzo sedation.

ACTH-derived nootropic peptide used in Russia for stroke and cognitive support; popular nasal nootropic abroad.

Oral triple monoamine reuptake inhibitor (dopamine, norepinephrine, serotonin) studied for substantial weight loss; not a peptide but listed in oral research-capsule catalogs.
