I bought cerebrolysin which, according to the label was produced in february of 2019 by Ever Pharma and expires in 2024. The label is in Russian but I read it with an iphone translator app.
I injected 5ml into my thigh and noticed absolutely nothing whatsoever.
Next day I injected 10ml and noticed nothing.
Next day I did intranasal 1ml and noticed absolutely nothing.
The day after I did intranasal 2ml and no effect.
With 3ml intranasal today I got a headache.
Before anyone comments, "You're supposed to take it for weeks or months before you notice anything," no, this is not the case.
Cerebrolysin is said to contain about 20% peptides and if the cerebrolysin I bought contains neurogenic peptides then SOME effects should be felt immediately.
Nerve growth factor and brain derived neurotrophic factor's effects upon the brain and nerve growth are felt within milliseconds, although for full repair of the brain it obviously takes much longer.
Others claim to have experienced an analgesic, antidepressive, energy-promoting, clear-headed effect, and other effects. I can say for certain I experienced no such thing.
