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.
Melanotan II
Melanotan II binds non-selectively to all five melanocortin-receptor subtypes (MC1R-MC5R). Via MC1R in melanocytes, eumelanin synthesis is stimulated (pigmenting effect). Via MC4R and MC3R in the CNS, appetite, sexual function and blood pressure are modulated. The cyclic structure and D-amino acids increase stability compared to natural α-MSH.

Frequently asked questions
- What is the difference between Cerebrolysin and Melanotan II?
- Cerebrolysin is classified as "Onderzoek (overig)", while Melanotan II 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. Melanotan II: Cyclic hepta-peptide and non-selective melanocortin-receptor agonist. Originally researched at the University of Arizona as a sun-protection concept — never approved as a medicine. Widespread on the black market; regulatory warnings for cardiovascular and oncological risks. This page contrasts both neutrally and source-based — with no usage or dosing recommendation.
- Which peptide is better supported by science, Cerebrolysin or Melanotan II?
- The highest available evidence level is "Humane RCT" for Cerebrolysin and "Humane studie" for Melanotan II. 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 Melanotan II in Germany and the United States?
- Duitsland: Cerebrolysin — Onduidelijk, Melanotan II — Niet goedgekeurd. Verenigde Staten: Cerebrolysin — Niet goedgekeurd, Melanotan II — Niet goedgekeurd. These are factual summaries with source and review date on the individual pages.
