What got worse for some people
In their own words
“After that I could get the same result about 10% of the time, with the other 90% being brain fog and a complete lack of focus.”
“Noopept's effect is gradually building. I've noticed a baseline improvement before dosing, as well as improved sleep, better short and long term recall, and serious increase in verbosity/speed of speech.”
“it turned me into an extremely depressed person with ADHD. I couldn't focus, I would forget something that was said to me five seconds ago and I would frequently have suicidal thoughts.”
“Tried some noopept and been taking 20-30 mg daily. I now feel like my normal self again, doing the things I love again, and performing well at my job again.”
“Noopept helped me a LOT... It also works as an antidepressant for me. The only side-effect I've noticed is decreased hunger. Sleep quality is also greatly increased.”
“I've noticed improvements in language skills as well as my ability and willingness to empathize with people, especially people I don't know. I've noticed increase in ability to be mindful.”
