It's very effective at first even if I only took only one scoop. However, I soon built tolerance quickly after taking it for a week. Good for beginners but bad for hardgainers. Taste is just Okay. At least, unlike BSN NO-Xplode, there is no foam.

I've taken this product for 8 weeks. It says 1 to 3 scoops per workout on label. For the first week I took a scoop and felt tingling during my training. Respectively on 2nd and 3rd weeks I added 1 more scoop so on my 4th week I was having 3 scoops. After week four I couldn't feel anything because my body built tolerance to this product quick fast.
Overall: This is a good product but with a big downside. My body build tolerance to it extremely fast (even though I wasn't taking any stims for couple of weeks before this product).

Effectivness(8): If you need pure energy this product is awesome. Normally my trainings take 45-55 minutes but with Rocked it was 30-35. Only problem was sometimes I had exCEEdingly bad heart beats.

Taste (6): I had lemonade flavour. It was bitter-sour but nothing bad with that.

Value (5): As I'm shipping it from other country it was expensive product for me. If you find local store where you live I don't think you will experience the same problem.

Mixability (9): It takes around 30 second with shaker to be totally dissolved in water.

Overall (7): If you want to try some new stimulant it should be a nice try. Also have to mention that if you check ingredients you can see that it's a kind of copy-paste from Jack3d. They both have exactly same ingredients.
