Cerebrolysin
Cerebrolysin is a mixture of low-molecular-weight peptides (predominantly below 10 kDa) and free amino acids obtained by enzymatic cleavage of lipid-free porcine brain proteins. The manufacturer and preclinical literature describe a neurotrophic and neuroprotective mode of action said to mimic endogenous neurotrophic factors; cell and animal models have reported effects on neuronal survival, synaptogenesis and anti-apoptotic signalling (including PI3K/Akt). Because it is a complex, incompletely characterised mixture, the precise mechanism in humans remains unclear.
Oxytocin
Oxytocin is synthesised in the hypothalamus and released via the posterior pituitary. Peripherally it binds the oxytocin receptor, a G-protein-coupled receptor, and through the phospholipase-C cascade and calcium release triggers contraction of uterine smooth muscle and milk ejection — the pharmacological basis of the obstetric approval. Centrally, oxytocin acts as a neuromodulator and has been linked to social bonding, trust and modulation of stress and anxiety circuits. Its central effects in humans are mechanistically incompletely understood, particularly because it is unclear to what extent peripherally or intranasally administered oxytocin crosses the blood-brain barrier.

Frequently asked questions
- What is the difference between Cerebrolysin and Oxytocin?
- Cerebrolysin is classified as "Onderzoek (overig)", while Oxytocin is classified as "Onderzoek (overig)". Cerebrolysin: Cerebrolysin (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: 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. This page contrasts both neutrally and source-based — with no usage or dosing recommendation.
- Which peptide is better supported by science, Cerebrolysin or Oxytocin?
- The highest available evidence level is "Humane RCT" for Cerebrolysin and "Humane RCT" for Oxytocin. A higher evidence level means more robust data, but says nothing about suitability for an individual. The full body of evidence is on each peptide's own page.
- What is the legal status of Cerebrolysin and Oxytocin in Germany and the United States?
- Duitsland: Cerebrolysin — Onduidelijk, Oxytocin — Op recept. Verenigde Staten: Cerebrolysin — Niet goedgekeurd, Oxytocin — Op recept. These are factual summaries with source and review date on the individual pages.
