GNC Pro Performance AMP Men's Ripped Vitapak Non-Stimulate, 30 Count

This is strictly from an energy boost point of view. I can't say for sure that the waterex or CLA does exactly what I need it too. I've tried other vitapak's from GNC, as well as other energy supplements from high to moderate stimulant/caffeine content. This has been the best overall product for me. The absence of caffeine is what does it. That said, it doesn't quite have the kick that others do, though you won't experience near the side effects either, such as "jitters", uneasiness, or you know, the tweaking out feeling. This gives me just enough boost in the morning, I take it after my breakfast, that I can take all but 2 of the CLA, (the other 2 at lunch) and the waterex, (which I'll take right after the workout). It used to be that I'd love whatever I had right out of the gate, then after 2-3 weeks, it'd be too much so I'd have to take some time off. With the non-stimulant, I can continue on week after week at 5 days/week working out/consuming, and not have any issues. That's primarily the goal I had, was an energy boost. I also happen to like beer...a lot of it, so my diet probably doesn't fit what one would to make this product work perfectly, but I do definitely get the right amount of energy each day.

I have taken many pills and other supplements, with results ranging from an amazing rush to nausea. With this product, I can't say much: No rush, no nausea. I'm not sure it works. I mean, about 1 month ago, I stopped taking supplements, and I lost 5 pounds, and still have the energy to exercise as I used to. It might be a coincidence, as perhaps my body needed the break after taking supplements (stimulants, proteins, creatine, etc.) for 6 months. I'll try this again in a couple of months (I haven't finished the box).

I've used the ripped product in the past but I used the one withthe stimulants and it did cause shakes/brain meltdown at times. It worked but i didn't like the stimulants so I decided to try this version, seems to be working as I've lost 9 pounds since Dec 27th. I eat a yogurt and protein for breakfast then a salad for lunch and a regular somewhat healthy dinner and its working so I'd say give it a try. I work out 4-5 days a week - 30 min cardion & 30 min weights. I always wonder if its a placebo effect but which may be it is but the one thing I notice if I eat lightly I dont get headaches etc so if it helps me control my diet in a healthy way then its a win for me.

I thought I was the only one thinking something was different with this product. I took these a year ago and loved them. But when I ordered this time I knew something was missing. Seemed washed down. Definitely not the same. But seems to be the same price. How is that? Will not order again unless they go back to the old formula.

I decided to try the non-stim and it works just as good as other stim packs. You get the same effect and sweat just as much as the regular stimulant pack but it doesn't dehydrate you and make your heart beat as much as the regular pack. Overall a good vitapak. Get the sweat and thermogenic effect with proper cardio.

I been using it for only eight days now. I have been exercising a lot. Eating a healthy diet. But so far I have gain two pounds. I thought by the end of the week I would have lost at least 5 pounds. Physically I don't see any improvement or any energy boost. I feel as tiresome as usual. Yesterday I took my pills at 8am and was sleeping from 1pm to 3 pm and woke up very tired. I drink all my pills in the morning with breakfast and drink lots of water. The yellow pill I usually take it in the afternoon before doing my daily work out. But nothing. After all the work putting together I still dont see the desired results. I will keep taking the pills until the end of the month and post/edit if I see any difference, positive or negative.

I have never been let down by products from GNC, and this was no exception. From day 1 of trying it with the amount of vitamins level and and minerals my body started feel better and work more effectively I highly rate this products and I will continue to use this product

My husband like this vita pack. 2nd time purchasing, but through amazon this time. Came promptly, and the price is nice.
