It was ok
Size: 2 Fl Oz (Pack of 1)
It tastes better than all the alternatives I’ve tried, but it makes me wonder if it is more sugar and less potency because I didn’t feel a noticeable difference after taking it like I had with some other brands. It also is a much fainter blue than the others I’ve taken…like it is possibly less concentrated(?) Anyhow, I could tolerate the flavor right out of the dropper unlike any others I’ve tried, but I’ll probably try a new brand next time as this wasn’t my favorite.

Great so far
Size: 2 Fl Oz (Pack of 1)
I started using this product about a week ago. I take it first thing in the morning on an empty stomach. So far and in the short amount of time I can tell that I'm having more constant energy that I had in awhile. Still to early to speak about other changes but I'm sure I will see more as the time goes. Definetly worth the buy.

Wow!
Size: 2 Fl Oz (Pack of 1), Size: 2 Fl Oz (Pack of 1)
I only started with a half dose and I can definitely feel the mental clarity. I feel hyper focused. My energy level did not necessarily change yet, but my focus definitely did. As I work my way up to a full dose I’m sure the energy levels will change. I went straight water with it and did not notice any kind of taste. The dropper is marked with dosage so the ease-of-use is great.

Gives a nice lift.
Size: 2 Fl Oz (Pack of 1)
Pleasant blueberry taste. As some other reviews have noted, it’s not the strongest Methylene Blue, but it does give me a gentle energylift in about 15 minutes.
