    Love the taste of this and is the perfect pick me up when I have a late sports game or not motivated to be awake, wakes me up, keeps me awake long and I don’t “crash” after a few hours.

    Previously reviewed and hated. Talked to a trainer at the gym and decided to give it another go…turns out I actually love this product.

    The blueberry mojito flavor is definitely superior than the other flavors considering the after taste. But as far as the performance it kicks in right away without the gitters and gives that extra edge in the workout. Even if you are really out of shape, like myself, drinking the pre workout does not give you to choice to not use the extra energy.

    This is a good product. Gives me enough energy to function and work out but doesn’t give me a heart attack. Blue mojito tatses like blue lemonade.

    Great for energy during workout without the jitters. Also great for muscle soreness after workouts

    It tastes pretty dang good, and it doesn’t taste as artificial as energy drinks. I found that it doesn’t give you the same energy as pre-workout might but it still gives you energy to focus and have a good workout session. For those that prefer a more focused workout over just having a crazy amount of energy pumping threw your vein type workout, then this is the product to purchase. Also, the flavor Blueberry Mojito is awesome

    I love this supplement. I use it in my smoothies in the morning. It adds a great taste and a good energy boost to get me through the morning. Much healthier than coffee, soda and energy drinks.

    Taste = phenomenal. No beta alanine so won’t get the itchy feeling and if you need more caffeine (serving = 2 scoop = 160 mg, add another). I use this in the gym or as a replacement for coffee when studying and will continue since the added BCAAs make it even a better product.

    I’ve been through a lot of supplements, and after sorting through all the hype and pseudoscience, this is the one that remains valuable to me. It has the essential double benefits for working out: jitter-free energy and full-spectrum aminos to feed the muscles. Doesn’t matter which flavor you prefer, they all work.

    Probably my favorite product and I drink all sorts of pre-workouts but this one is nice for just a casual day it’s not going to make you nervous or jittery it’s just a little energy boost I have not had any ill side effects your first time I would recommend two scoops and then worked your way up from there if you feel like you need more

    I love amino energy and have been using this product for about 2 years now. It gives me a nice boost when I am dragging through a long workday, and I drink it every day when I work out. I have replaced my pre-workout with this product and recommend it to all of my family members. In my opinion, the best flava is pineapple.

    Love this stuff, take a scoop twenty minutes before lacrosse games and another during half time. One of the few pre-workouts I have taken that does not make me feel anxious or feel like it makes my heart beat too quickly for a running sport. Would definitely recommend. I don’t enjoy it too much for weightlifting or crossfit style workouts however. The price is hard to beat as well.

    I absolutely love this. I use it in the morning to get some energy, and it’s great as a preworkout. I love that I don’t crash from the caffeine, and it’s just great! For anyone wondering, all supplements in my experience are never all the way full. This is about half way filled but it still has the same amount of servings as stated. It’s a great price, quick shipping, and I will be buying again.
