I play tennis so these vitamins give me the boost I need.

[This review was collected as part of a promotion.] I have been using this product for over 10 years and it's the best. I take it first thing in the morning and it's starts working in 10 mins and my energy is great. I definitely recommend this product if you need energy and loss a little weight.

[This review was collected as part of a promotion.] Definitely give you an energy boost, and has a ton of great ingredients for men's health! I suggest splitting half the pack up between 2 parts on the morning. They can be strong if taken all together and may affect sleep if taken to late in the evening. Great product, highly recommend.

Best way to get daily vitamins and caffeine. I have been taken these for 5+ years. Only downside is the dark brown omega3 pill. I never take it because it makes me burp and the aftertaste of said burp is not good. Side note I don't like seafood either. I always toss out that one pill when taken.

Mega Men Energy & Metabolism get a five star in my book. I definitely feel the results.

I been taking vitamins for a while now I can guarantee they work incredible my brain is on let's go let's do this mode all the time don't take caffeine with it lost if water lots of it n u good

Makes me extremely jittery. Had to stop taking. Tried to break it up throughout the day but didn't help.

Not the same as when I first discovered them and seems like the formula keeps changing with the number of pills you get as well as the look of them. They don't give the same results or feel the same as previous purchases. Returned and will start to look for another product.
