Black Star Labs GO!

Effectiveness 9/10 - I have tried a lot of pre-workout energizers and focus supps (no-xplode, AMP, etc.) and this may be the best I have ever used that is designed specifically for this purpose. It seems like no matter how exhausted or run down I am, just a few scoops of GO! and I feel ready to destroy the iron. It is not a bouncing off the walls or jittery feeling, but rather a very focused feeling with pleanty of energy to accomplish any task. It lasts for a good amount of time, around 3 hours depending on the amount used, and I never experienced a crash of any sorts either.

Taste 8/10 - I tried the fruit punch and while a smooth flavor, I think my expectations were a little too high from bsl It is not very tart or too sweet, I think I was just expecting kool aid. However, this is by no means something you need to slam.

Mixability 8/10 - completely dissolved in about 12 oz. of water with no effort, but it was a little clumpy coming out of the jar.

Price 9/10 - for 19.99 (or 9.99 if you can get it), the price is fantastic.

Overall 9/10 - This gets nowhere near the appreciation it should. Fantastic supp that more than performs.
