GNC AMP Strength Vitapak Program, Performance And Muscle Support, 14 Daily Vitapaks, 14 Servings

I was strength training using gnc's amp strength vitapak hitting a new PR every workout for 2 months straight granted I stacked it with gnc's amp wheybolic strength protein, but still feel like these helped tremendously to get over the hump daily to prevent myself from plateauing. I hit every muscle group til failure twice a week performing supersets one of the days for a more intense session & iso workouts on the other for extreme focus targeting mind to muscle connection & that resulting to me being able to lift at least 5-10lbs more than my previous PR I hit earlier in the week as well as going up 2-4 more reps of my previous PR. It truly felt like a cheat code in all honesty. Great product overall

Best package out there my favorite for ever my best friend

I have tried several different vitamin packs and this one surly hits the spot. Not only does it help with my strength, it gives me energy even when I am dead tired. I am approaching 50 fast and can use all the assistance this vitamin pack gives to get me through my workouts and to try to restore my fountain of youth. I highly recommend it....

Purchased this item to help build my immune system. It has only been a week however; I already feel a drastic difference with my energy, and alertness. I am a 57 year old male and do not work out. I purchased these supplements as they appeared to have all the necessary nutrients. I was pleasantly surprised how quickly I began to feel.

5 stars. Out of everything I have tried to take this is by far the best. The pills are prepackaged. No guessing the amount. And am seeing results using Mens Strength. Will continue to purchase.

as a 51 yr old this does make a difference. i take only for 1 week a month then cycle off as to not let my body get used to it. it helps when lifting better pumps and notice it helps my strength increase.

Im 70% sure that it works, it has helped me with my strength I do feel stronger and I can go heavier, they also make me feel full though all day, I dont feel too hungry through all day. It does make my urine really yellow, just need to drink lots of water over all.

Not sure the creatine is where or what it needs to be. Haven't noticed any additional value from it being added.

I began taking this product for energy and to increase workouts, but after finishing my second box, I began with a pain under my rib cage and found out that the product had caused a fatty liver. Now my liver has slowly been normalizing after I stopped taking this supplement.

I've been using this for 3 weeks..I Excersize 6 days a week and I Can not definitively say that I've notice a difference in strength or size as a result of using this product.. Prior to using this product I used Animal Pak by universal nutrition and it was great..anyway this purification, in comparison to AP, has made me feel tired and really sluggish while Excersizing. it may work for others but it is not working for me..I will finish the 30 days and cycle on something else..I will say GNC SPort supplement was very effective when I first started using it earlier this year..
