Cognition & Focus
Attention and memory performance. A group of Russian Pro-Gly-Pro peptides (semax, selank) has been investigated; replication in Western RCTs is limited.
Peptides on this topic
4 peptidi con ricerche su questo argomentoCerebrolysin (FPF-1070) is not a single peptide but a porcine-brain-derived preparation of low-molecular-weight peptides and free amino acids, produced by standardised enzymatic proteolysis. It is approved in several countries (including Austria, Russia and parts of Asia) for stroke, dementia and traumatic brain injury, but is not FDA-approved in the United States and not centrally approved by the EMA. Its efficacy is contested: Cochrane systematic reviews found no convincing benefit and flagged possible harm signals.

Oxytocin is an endogenous nonapeptide hormone of the posterior pituitary. In synthetic form (Pitocin, Syntocinon) it has been approved for decades to induce and augment labour and to control postpartum uterine bleeding. Strictly separate from this is intranasal use to influence social behaviour, trust, anxiety or autism symptoms: this use is unapproved, purely experimental, and yields inconsistent and often negative results in controlled trials.

Synthetic heptapeptide derived from natural tuftsin. Approved as an anxiolytic (Selank) in Russia and some CIS states. Western phase-3 trials are absent; efficacy assessment relies on Russian research literature.

Synthetic heptapeptide derived from the N-terminal fragment of adrenocorticotropic hormone (ACTH 4-10). Approved in Russia for ischaemic stroke, cognitive function and ADHD in children. Western phase-3 trials absent.
