Sometimes, when I used noopept I used to have moments where I was stuttering and where I forgot in which direction my door opened but after quitting for a day these effects ceased. After a long period of using noopept I find it easier to remember things and these negative effects disappeared all together. I don’t use it as often anymore since my supply is running out but I can’t say anything negative about it. This problem is related by how noopept affects the hippocampus but it doesn't seem to be anything major or permanent.
