5-hour ENERGY Regular Strength Energy Shot, Berry Flavor (1.93 oz., 24 Count) Zero Calories & Sugar-Free 200 mg Caffeinated Shot, Amino Acids & B Vitamins, Dietary Supplements

Very happy with this product! It delivers a quick and noticeable energy boost without the crash. The watermelon flavor is surprisingly pleasant and not overly sweet. I also appreciate that it's sugar-free and low-calorie. Great to have on hand for long workdays or early mornings—definitely a staple in my routine now.

Used these for years. No side affects.Great product. I always take them in the car if I’m going on a long trip. If I get sleepy, just take one and I’m good for five hours. Also good for people who tend to fall asleep in church.

I love my 5 hour energy shipments from Amazon. These little bottles pack a powerful punch. They are equivalent to drinking 3-4 cups of coffee. They help me to stay awake and be alert, especially when driving long distances. And they do not add a lot of calories like sweetened coffee products. They also have some essential vitamins and minerals. I particularly enjoy this flavor the most.

Use these all the time. Sometimes just have half a bottle with great results.

If you love love love watermelon this is for you.I saw it was a great deal vs the grape which is my fav.I am not a fan- it’s def not the flavor for me.:(BUT THEY WORK GREAT!!!!! Personally - I take 1/2 at a time and space it out otherwise it upsets my stomach. Also helps with the jitters and still gives you the same energy just take 1/2 and 1/2 and you’re good to go.

Ever since I discovered these energy drinks, they have become a part of every morning. I don’t feel that I need to have one, like coffee, or other stimulant type of caffeine drink. I just like the taste, and the way that it energizes and starts my morning. One issue to be aware of of course is the fact that five hour energy does contain niacin. That’s not a bad thing. It’s just important to note that you should not drink the entire bottle all at once, particularly if you have had any type of low blood blood pressure problem in the past, or you are taking medication for blood pressure. The niacin may cause a niacin rush as it is known and this may make you feel a little faint. Some people have actually reported that they drank the entire bottle and then fainted for a moment onto the floor. The bottle itself warns against this and does indicate that you should not drink the entire bottle all at once. For me, I break it up into three parts I take a drink and then perhaps get dressed or take a shower then I drink another third, and perhaps read the daily newspaper or answer email and then by the time I get into the car after about 30 or 40 minutes I drink the final third of the bottle. That is perfect for me no effects no dizziness and I am fully energized for the morning some of the flavors are not real wonderful, so choose the one that you like the best. For me it is the berry. I don’t particularly care for the watermelon.

Flavor is strong but tastier if refrigerated prior to consuming. Works as described.

Great
