I have been incredibly impressed with Qualia so far. I've used a few nootropics in the past and had mixed results. Sometimes there was no noticeable difference at all, and other times there results were sometimes noticeable.
With Qualia I had immediate and powerful results. It took a while to get into the habit of using it regularly, but now I very much enjoy the clarity and focus it provides. I've also noticed that it seems to work best when I support other healthy behavior such as exercising.
I've noticed that Qualia helps a great deal when I am working on things that I truly care about, like music production and graphic design. There have been some days that I spent just reading internet articles or boring repetitive tasks and it doesn't work as well. But if you feed your brain with something engaging Qualia will greatly improve your experience.
The benefits are fast acting and last the entire day (or longer). Highly recommended!
