Took a while to work for me I wanted to write a review because this took a while to work for me. I'm about to start my 3rd round now and it's only because I realised about a month after my second round that on the whole I have less brain fog and thinking is generally easier for me now. I have had me/cfs for about 16 years, but unusually it seems my cognitive function was hit much harder than most for me/cfs. I maybe experienced one day when I felt improvement on my 1st round of 5x 5ml (for 4 weeks) cerebrolysin, but it disappeared very quickly, and I almost didn't bother with trying again, except that I'm desperate to get my brain function back. During the 2nd round of 10ml x5 (for 4 weeks) I thought maybe something was happening, but it was so subtle I couldn't be sure, and after the course I simply forgot all about cerebrolysin until I had to do quite a bit of thinking for a period. I realised I wasn't struggling as much as before and the brain fog was less and mental stamina was up. That was 6 months after trying Cerebrolysin for the first time that I noticed any improvement. My point is I'm glad I persevered. I'll update after my 3rd round. I've also never had a problem with any of my orders reaching me in the UK!
