Noticed first off that my short-term memory became sharper and easier to manage; felt like my brain's "memory stick" had been upgraded to a higher performance one. First week intake gave me lesser brain fogs as a result, and I even became more fluid with my speech and conversations; words came into my mind easier. I will never regret getting my first bottle, and will for sure get more when this bottle runs out (pair it with Modaf plus the other NS brain supplements as a part of your stack, you'll feel like the star of Limitless). You're welcome.
