Effective Vitamins

I have used GNC Products for several years. These vitamins are quite smaller than the ones I have taken before, which is nice. I have am happy with the size and the effectiveness of these vitamins. I will definitely continue to use GNC Products.

Great product

I buy these for my son. He is in his 30’s and has a stressful job which wears him out. He says they work well. I feel GNC is a great brand and Sam’s has a great price.

2 per DAY. MISLEADING PACKAGING! 120 pills=60 DAYS

Didn't notice ANY DIFFERENCE in my Energy Levels. VERY EXPENSIVE!!! @ 2 pills per day , the bottle does NOT LASTB LONG!!! LESS FILLERS and MORE CONCENTRATED pills COULD lead to a more HONEST PRICING and use model!!!

GNC Mega Men Multivitamins Gives me great energy.

I have been using GNC Mega Men's multivitamins for a couple months now and I feel I have improved strength and a lot more energy. I take one everyday with my workout regiment and have been very pleased with Stamina it has increased dramatically. I have not had any side affects. I'm a type II Diabetic and feel this has helped me be more energized and in turn has helped me lower my A1C numbers.

Good product

I take MegaMan before I go to work in the morning. I started off taking one instead of two in the morning. Then I switch to taking two in the morning. I have a lot more energy during the day at work. I don’t have the jitters like I do when I drink energy drinks. I am a lot more alert at work.

Energy!

I have been taking this product for a week. I have noticed an increase in my energy! The first few days, it really upset my stomach. I take my capsules with breakfast and lots of water throughout the day. Once my stomach got used to it, I began to feel a great increase in energy. I have energy throughout my work day instead of getting sluggish in the afternoon. I have also noticed I feel less bloated. I plan on continuing this product for another few weeks and then writing another review after my body has had time to adjust fully.

Solid multivitamin with caffeine

I have been using this vitamin at work to give me a boost here and there when I feel my energy dipping a bit. Coffee has not been agreeing with me, so I decided to try this product to see if it is a decent replacement. Overall, I have been pretty happy with the results. There is additional energy, and I don't get any ill effects that I have seen.
