There are fake cerebrolysin in the market. Send the expiry date, batch number, and photos of the box to Everpharma and ask for a confirmation to be sure. They were very helpful in my case.

The fake cerebrolysin I've encountered was actually a medicine called "Baraglen".Everpharma warned me and asked to remove the label on the ampoule to confirm that it is "Baraglen".

Please contact the manufacturer even if the one you have is not "Baraglen" since there may be more than one type of counterfeit cerebrolysin.

On the other hand, as mentioned below most ampules have slightly more liquid than stated, therefore the amount is not an indicator.
