It’s been a long journey but I feel I’m now qualified to advise you on whether or not to try GNC Pro Performance Vitapak. We decided to conduct one of our comprehensive reviews, taking a close look at the ingredients, side effects, clinical research and customer service. Plus, we went on to read hundreds of user testimonials from across the internet. Then, we summarized and condensed it all to give you the bottom line.

What is GNC Pro Performance AMP Ripped Vitapak?

Firstly, GNC Pro Performance AMP Ripped Vitapak is a collection of four different supplements including the Mega Men sport blends, CLA, Thermo Igniter 12X, and Waterex. The Vitapak is to be taken daily, but not before bedtime as it may cause interference with sleep because if the stimulants in some formulas. The pills are easy to travel with, one good thing.

Pro Performance AMP Ripped Vitapak is produced by General Nutrition Corporation (GNC). The company has more than 80 years in the business and you can purchase the product from the official website. We like the longevity and some of the ingredients will support overall health, but read on…

Reports of Ineffectiveness – “Doesn’t Work?”

The first thing that concerned us was the ineffectiveness of the GNC Pro Performance Vitapak ingredients. Despite the fact GNC is a popular supplement brand, there are reports that the formula doesn’t live up to expectations. “All you want out of a product is for it to work,” says our Research Editor. “Otherwise, why are you even giving it the time of day?”

“I have been on this program now for over two months and have not lost any weight, even though I run about 12 miles a week and also go to the gym every day. Did not notice any type of boost of energy!,” said one user.

We also read a review that said, “I took the pills everyday while working out everyday for a month, and there was no additional effect.”

On the other side of the debate, there are people who felt the increase in energy and lost weight.

“I’m currently on day 2 of taking the pills and I have noticed and instant difference. I have more energy than ever,” said a user.

Another shared, “It helped me drop [weight] in 10 weeks (with a strict diet plan and dedicated work out schedule).”

Negative Side Effects – “Not a Positive”

Several user reviews indicated issues with the supplements; from headaches and nausea to feeling dizzy, it seems that some of the ingredients in GNC Pro Performance AMP Ripped Vitapak may cause problems for users.

One user said, “Hated it! Pills are huge and It will make you stressful. One weird thing is that it making me dizzy!”

“I really wanted to like it. I tried every single combination to take these and it did not work out. I was left feeling not so good every time I took these,” said another.

This wasn’t an issue for every customer who tried the vitamin pak.

As one claimed, “Only side effects is frequent neon yellow pee.”

“Besides the normal side effects of 200 mg of caffeine, I have had nothing out of the ordinary,” shared another.

Our research indicates that if there’s part of a diet program that’s difficult, like the potential for side effects, the chances that a dieter will see long-term results are diminished. If GNC Pro Performance AMP Ripped Vitapak does lead to adverse reactions, there’s no real reason to spend the cash.

The Science – “Effective?”

There is no science to support this product as a whole. Waterex is a diuretic to help remove excess water weight. However, using supplements like these too much can cause dehydration by robbing the body of water it needs to be healthy. Especially when you take into consideration that caffeine is an ingredient and that can cause you to lose more fluid. At DietSpotlight, we need to see clinical backing for the ingredients. If that’s not available, we immediately throw the red flag.

The Bottom Line – Does GNC Pro Performance AMP Ripped Vitapak Work?

Are we on the run to pick up all of these? We were looking forward to reviewing GNC Pro Performance AMP Ripped Vitapak because it appeared to be a solid supplement from a well known and respected company. We were disappointed to see a number of complaints about the products doing nothing but changing the color of urine and, in some cases, causing headaches and nausea. For these reasons, we are skeptical about suggesting dieters give this one a go.

If you’d like to drop pounds, we suggest opting for a supplement that combines clinically tested ingredients with a great price and no risk of side effects.

Among the best products we’ve seen in 2016 is one called Leptigen. The formula is a proprietary blend of four ingredients clinically tested and shown to help you boost metabolism and lose more weight. There’s no talk of harsh side effects and comments all around the internet show people are seeing great results.

Also, the makers of Leptigen are so confident in their product they’re offering every customer a Special Trial Offer – amazing incentive.

One product manufactured by GNC, which is marketed specifically at men is GNC Pro Performance AMP Ripped Vitapak. The cost of this supplement is $54.99 (30 packs). It can be acquired from local GNC stores, as well as online. Over 50 different ingredients are used in this supplement to assist the body.

Product Features

GNC Pro Performance AMP Ripped Vitapak is a supplement formula that is supposed to help men get a tight and chiseled physique. More specifically, this pill combination aids the body by boosting energy levels, reducing excess water weight, burning off more calories, fueling muscles, strengthening the immune system, and preventing joint damage. This product is geared toward athletes, and people who exercise regularly, and stay active. No special diet plan is encouraged with GNC Pro Performance AMP Ripped Vitapak, and no 100% money-back guarantee is mentioned. As for the major ingredients found in this formula, these are revealed as Waterex (reduces water weight to reveal muscle definition), Thermo Igniter 12X (increases energy and endurance, while boosting the metabolism), Mega Men Sport Blend (B-Vitamins, Amino Acids, and Antioxidants are used in this blend to boost energy levels, aid the immune system, and prevent damage to joint cartilage), and CLA (four grams of this ingredient is provided to support lean muscle mass).


  • This product offers four separate pills to address different concerns.
  • You can find this supplement in common GNC stores.
  • Each serving is provided in a separate packet to make things easy.


  • Some users complained that this formula is ineffective.
  • The price of GNC Pro Performance AMP Ripped Vitapak is high for a one-month supply.
  • Some men will not like taking four different pills/supplements at once.
  • This formula likely contains ample caffeine, since it is not okay to take in the evening.


Overall, the convenience of GNC Pro Performance AMP Ripped Vitapak will appeal to some guys. After all, it is easy to just grab one packet of supplements and take them on the go. However, the drawback to this convenience is the cost. $55 each month will likely get expensive. Secondly, some men have stated that this formula does not work as claimed. On a final note, there is likely a great deal of caffeine or stimulants used in GNC Pro Performance AMP Ripped Vitapak, since it is not okay to take in the evening.

This is my 7th week going on this product and I have dropped about 18 pounds. I am at the gym 6 days a week and have started eating more healthy but still pop some chocolate or a cookie and cheese into my diet throughout the week.

Ramon Ortiz

Just started so i realy canr say but ill get back to you in like a week or two and the olny thing is my peevis yellow .


You stated that some guys have said it didnot work, but why no reviews of thise who said it did? Sounds as if you are biased in your review of the product.


I just started taking it 3 days ago, I’ve had a six pack for years now and I just want to see if it will take me to the next level, I’m just worried about the color of my pee, it’s really yellow and I’ve heard it’s bad for your liver as you are making it work harder, but I guess a month won’t hurt


Drink a lot of water. That color is due to a high concentration of the vitamins. If your water intake is sufficient, the color is diminished significantly

Davian Smith

Am worried about the same the thing my pee is yellow but other than that everything works great I can now see my muscles carving out this stuff good


I have been using the Vitapak for years I like the vitamins in it along with the water pills etc. I just received my new shipment in the mail and noticed the formula has changed and they have removed the CLA. Can you do a follow up as to why? Is it now less effective?

Stephen (Editor)

Often times companies change their formulas if either a particular ingredient is banned in the country of manufacture or if they have received a number of complaints or issues related to the ingredient. In this case it is as yet unclear with them having just changed it. As you continue to take it give us updates on its efficacy.
