This is subjective, but we base it on the views of our testers, as well as what the general consensus is in online customer reviews. We took the individual flavor and full range of flavors into consideration.

Bear in mind when you last ate can affect when you start to feel the effects of the pre-workout as that will slow down digestion and absorption. How long a pre-workout lasts depends on how much caffeine and or other stimulants are within the product.

The more stimulant, the longer it will last. Most stimulants sustain their effect in some manner for four to six hours after consumption. A powder may be better if you struggle to adequately hydrate yourself as this will be a passive way to take in more fluid, however the choice really depends on personal preference.

Both would have similar effects, however a powder may also provide more rapid effects as it begins to absorb through receptors in the mouth. That depends on your tolerance, however research based effective dosages typically range from anywhere between to mg a serving.
