GNC AMP Men’s Extreme Training Vitapak Program, Vitamin Pack for Performance & Endurance With Proven Ingredients, Caffeine, Nitric Oxide, 30 Day Supply

This one I like. Worth it. Especially when there's a GNC products Bogo sale.

Great supplement. I have noticed a faster muscle recovery and I feel mentally sharper while on this. This has made me feel better while cutting weight. Likely from negating nutrition deficits. My overall sense of happiness and mood have been great each day I take this.

Do NOT take after lunch. Woke up at 6a, took half the pack, took the other half after I ate lunch, when to sleep at 3am. Took a day off, and did the same thing, same results. Third time took them all at 6a, no jitters, but was wide awake at midnight. Good stuff. Just have to cut the pack in half for me. 38 year old. 200#

Very impressive, 33 years old , build pellets for Pepsi, picked 1364 cases last night , would recommend to everybody!! Also take fish oil , stay strong love God is the saying I live by!!!!!

took the whole pack all at once the first couple days and was a good rush!!!! almost to much, now i break it up half in the AM and half at lunch. these actually work paid 105$ for 2 months so not that bad

Hands down all the way legit. Like always it's a little pricey but as the saying goes, you get what you pay for and GNC ALWAYS DELIVERS. Looking to take it to the next level, stop bs'ing and step up. EXTREME TRAINGING VITAPAK

Great feeling when I take it. I feel well nourished and strong. Ill continue to buy this. Thanks!! -Roger

[This review was collected as part of a promotion.] Good vitamins. I have confidence that they are increasing my overall health.

Solid product. Gives the right amount of energy to get thru the day. Definitely feel the difference when I take it.

In every pack at least one pill was broken. Not worth the recently raised cost.
