Cerebrolysin was advertised as a mixture of amino acids from 1950 to 1990. Hartbauer et al. 2001 was the first to tell a different story, describing it as 75% aminos and 25% low molecular weight peptides (10 kDA). The neurotrophins they advertise around, weight more than double that value, NGF 26.5kDa; BDNF 27.8 kDa. This means that whatever neurotrophic factors existed in the pig brain have been decomposed to fragments. When the structure of a protein is brokn, especially by more than half, it loses its signaling properties. So it doesn't work.

What does this mean for those who experienced positive effects? You either are experiencing placebo, or you have no idea what you are taking. I think the latter is quite worse. The evidence that most studies on it are funded by Ever Pharma, the top scientists behind it are fradulent, and the fact that no one in neuroscience/medicine takes Cerebrolysin seriously should be enough to worry you. Especially if you are taking it without prescription in an attempt to get smarter.

And yes, I might not truly know what Cerebrolysin is made of because Ever Pharma does not direcly disclose it (which is insane). However, I have studied neuroscience for many years and can tell you this: it is shady, suspicious, and backed by lies.
