Flavor Name: Concord GrapeSize: 30 Servings Verified Purchase
Been using this stuff for couple years now. 2 Scoops (100mg caffeine) is all i need then its off to the gym. Keeps me motivated and focus. Nothing special, just simple pre work out containing caffeine and BCAA's.

BUY WATERMELON if you do not want artificial colors. Grape is a deep deep purple. So unnecessary in a health supplement product. Very counterproductive.

Flavor Name: Concord GrapeSize: 30 Servings Verified Purchase
I tried this product for 2 months now, and although I am extremely satisfied with the taste and amount of ingredients it has per serving, I am giving it 4 stars because it lacks the power I was looking for in a pre-workout drink.

- Taste -

Delicious! I will state though that the grape flavor is not my favorite, but the fruit fusion is by far extremely delicious when I drink it with ice water.

- Value -

Not bad, considering you are paying less than $1 per serving (beats getting a nasty sugar loaded energy drink)

- Benefits -

Depending on what you're into, this might or might not be the product for you. When I was training for a half marathon, this worked wonders for me, it provided me with the right amount of energy to prevent fatigue and did not dehydrate me at all. I would drink this 20 minutes before my workout and off I went. My wife really enjoyed the taste as well, and she like the fact that it did not give her any jitters or made her all shaky as other products I tried before. The supplements you get with this product are pretty good for recovery as well, since I was recovering rather well from long runs.

Although I never took this product too late in the afternoon, I never had any issues trying to sleep at night. I have come across some products that kept me up all night and it was more like a inconvenient side effect that superseded the benefits of the supplement.

- Cons -

I will be honest and say that although I did enjoy taking this supplement, the only bad thing I can say it that it does not carry the overall punch I was looking for in a pre-workout drink when I would do power lifting.

Flavor Name: Fruit FusionSize: 65 Servings Verified Purchase
This is product is a life saver for those who need a little extra boost at the gym to overcome the fatigue of a normal day. The amino acid blend is superb and the green tea and coffee "extracts" provide a noticeable boost in energy and drive. I've never felt jittery, shaky or "hyper". Its a nice energetic feeling. And the taste is very, very good. It mixes well in blender bottles which makes it nice to make one on the go.

If you're looking for a decent energy boost before hitting the gym, or even starting or trying to stay awake for the remainder of your day- give this a try.

Flavor Name: Fruit FusionSize: 30 Servings (Pack of 3) Vine Customer Review of Free Product ( What's this? )
I used to use a lot of supplements, but have, for the last few years, concentrated on getting most of my nutrition and vitamins from natural organic whole foods and from herbal teas and tinctures. They seem more absorbable this way. But I have found that I still use free form amino acid powders, like glutamine, GABA, and arginine. They are very absorbable also and when bought as a bulk powder seem to be a bargain for what you get. I was happy to find an amino acid powder up on the Amazon review list and was eager to try it, to see if I could feel anything from using it.

What I found is a few things: One is that this powder mixes well with water. It does not clump. Many powders are fussier to work with, do clump, and often need a blender to really mix with water or fruit. Two is that it has a nice tropical fruit flavor, a kind of like old fashioned Hawaiian punch. Three is that it has a measuring spoon for the right dose. This is very convenient (and also I like to keep them for measuring other things later on). Four is that I could feel some immediate "muscle recovery," some feeling of energy and strength very soon (10 minutes tops) afterwards.

There are a few reservations I have about this product, too: It says "natural and artificial flavors". This kind of blanket statement can hide a lot of not so good things behind it, even MSG. While I do not think this product has MSG, I cannot know for sure. It also has yellow dye #566. This is new to me and I do not know how to evaluate it. I hope it is okay. It also has "sucralose" as a noncaloric sweetener. While this is better than Nutrasweet (which to me is an excito-toxin), I would prefer to not use products sweetened this way.

I was looking for a pre work out powder, that worked good, taste good, and did not cost a lot. I found this one by scrolling through different powders. I really like it, it does the job like it is suppose to do, it really kept me going through my workout, I did not want to stop or rest during my work out, like how I normally would do at times. I always used the mild amount, and to me that works just perfect, and I do not want to over do it so I like where I am at on this. The taste is good, I got the fruit punch flavor and it taste like fruit punch, it does have bit of an after taste but very mild, nothing that is too overwhelming. It is also easy to mix, I filled my bottle up too 12 ozs and added 2 scoops and shaken it up with my metal mixer ball, and I would take it at my house before I would head to the gym, and by the time I got to the gym I was ready to go. One of my favorite things is that I really like that the spoon has a really long handle so when you scooped down at the bottom it give you enough reach.
