I've been on it for a month, 2 caps upon waking and 2 caps before bed. The first week I felt highly focused where I could literally feel some pressure in my brain and this was after I finished an 8 month run of Evomuse ClearEdge. After that initial week, the effects weren't as pronounced, but still wide eyed about things. Sleep has also improved. I bought two bottles and thought I could get the ingredients cheaper on Amazon, but if the price lowers then I'll continue to buy this instead since it's all in one and dosed generously.
I'm not sure if it's piggybacking on ClearEdge since I didn't really take time off that, I just went straight into TruNeuro. This has more acute effects from the first dose and somewhat tapered off. ClearEdge builds up over time with continued use.
I guess a better way of judging it is when I get off it which seems to be the case with most supps. They don't really seem like doing much when on it, but once you're off it, it's night and day. I just like to run nootropics as a staple year round and I'm afraid I'll turn into a zombie if I stop lol.
