This is the best pre workout and daily energy drink on the market. I was told about this drink from a General Nutrition worker that has crohn's disease, so he has to be very careful of disturbing his stomach. Well I also have stomach issues, and I take this daily because it gives me the energy I need without causing stomach pain or discomfort. The best part is there are no side effects! I hate the powders that cause tingles and anxiety, so I take this wonderful drink daily in all its flavors! Mango Peach (Extra Benefits), Fruit Punch, Grape, and Berry Bomb (Extra Benefits). Drink one of these with 500mg of L-Tyrosine and you're going to feel your absolute best, without the worry caused by some of the other powders and pills on the market today.

I'm a big preworkout drinker... I mean big! A couple times I've forgotten my pre at home and so I've tried these out from my gyms shop. These taste a little too sour and sweet for me personally. My main complaint is that I have no idea how much caffeine is in them! A fully disclosed label showing how much of what I'm putting in my body would be nice. Overall decent option for when my go to preworkouts aren't available

This stuff is the TITS (which is a very good thing)!!! It DEFINITELY puts pep in your step! I highly recommend it, as long as you're not sensitive to caffeine!

I go to the gym very early in the morning and need something to wake me up. Energy drinks make me way too jittery, but Speed Stack doesn't it wakes me up without making my heart feel like it's going to explode and without the crash.

I used to drink the Berry Bomb flavor while I was at work all the time and it's good to go! It's a convenient RTD, tastes good and does the trick when you're in a hurry and don't have your normal pre-workout or if you just need energy, it's more beneficial than other energy drinks.

This is a great pre-workout energy drink. I love the fact that it is pre-made and sits in my refridge waiting to be drank. It helps me get through a workout after a long day of work. I feel energized and focused when I'm lifting. So far, I have tasted the Berry Bomb, which is good. I definitely would recommend this product to others.

This is the only pre work out that works for me I have tried a few but this one is by far the best

Always go with the Berry Bomb! It's got it's own blend w/ additional adaptogenic herbs alone with the Mango Peach flavor. As opposed to the grape and fruit punch which has a smaller blend. Awesome, clean, consistent, and relentless energy. Tastes good, feels good, does the job. Built Greater than is the ONLY way to describe Speed Stack!

This product taste great and really helps you get that extra edge you need when everything else wont work.... I've had Grape and Berry Bomb but hands down the Fruit Punch is my Favorite... When this product kicks in i'm like the HULK nothing can stop me, and i sleep great too, especially knowing that i had a great work out...

Always makes me feel positive, awake and alert before a workout

All time personal favorite of mine! Good for busy work days, studying, riding and last but not least before and during workouts... It has a smooth sustained energy without a crash, and u can actually run a few miles with it in your belly without feeling like your heart is gonna pump out of your chest. However, due to its content of PHOSPHORIC ACID, i've greatly tapered down my intake.
