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.
Gonadorelin
Gonadorelin acts as an agonist at the GnRH receptor on the gonadotroph cells of the pituitary and triggers release of the gonadotropins luteinizing hormone (LH) and follicle-stimulating hormone (FSH). The temporal pattern of receptor exposure is decisive: pulsatile administration mimics the natural hypothalamic secretory rhythm and sustains LH/FSH release, whereas continuous exposure leads to receptor internalisation and desensitisation with subsequent paradoxical suppression of gonadotropins. The latter principle is exploited therapeutically by longer-acting GnRH agonists.

Frequently asked questions
- What is the difference between Cerebrolysin and Gonadorelin?
- Cerebrolysin is classified as "Ricerca (altro)", while Gonadorelin is classified as "Ricerca (altro)". 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. Gonadorelin: Gonadorelin is the synthetic decapeptide with an amino-acid sequence identical to endogenous gonadotropin-releasing hormone (GnRH/LHRH). Historically approved in several countries for diagnostic testing of pituitary function and for fertility indications (pump systems). A defining feature is the opposite effect of pulsatile versus continuous administration: pulsatile stimulates, continuous leads to receptor desensitisation. This page contrasts both neutrally and source-based — with no usage or dosing recommendation.
- Which peptide is better supported by science, Cerebrolysin or Gonadorelin?
- The highest available evidence level is "RCT sull'uomo" for Cerebrolysin and "Studio sull'uomo" for Gonadorelin. 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 Gonadorelin in Germany and the United States?
- Germania: Cerebrolysin — Non chiaro, Gonadorelin — Su prescrizione. Stati Uniti: Cerebrolysin — Non approvato, Gonadorelin — Su prescrizione. These are factual summaries with source and review date on the individual pages.
