This is a powder-based packet that can be added to water to provide and energy drink. I’ve tried it in the afternoon and it lives up to its claims. No jitters but improved energy and focus. The tropical punch flavor is good and doesn’t taste like chemicals or the bitter vitamin taste. It mixes well with water. I would recommend this product and buy it over some of the other similar items available.

I'm not much of a plain water drinker so I did like this product. The flavor is fruit punch but light, not overpowering like some fruit punch flavors. I like that they are individual packets which makes it handy on the go. As far as extra energy it did seem to help give a little extra to help me get through the mornings then I'd drink another around lunch to power through the rest of the day. Overall a good product. I will continue to use.

I’ve been taken the drink around 5:00 in the evening after work to give me the energy to do my workout on the elliptical. Seems to provide me with enough energy to complete my workout after a 10 hour work day. The mix dissolves fairly well in water and is a bit sweet. Definitely taste like fruit punch which makes it easy to drink. Does have a slight after taste but most powdered drinks do.

Great for every day use at home or on travel. Just mix a packet with 16 ounces of water and you are ready to go.It contains no sugar and zero calories. Use before your workout or when you need a mental boost to focus. I used this on my last family vacation and it helped me to have more energy during travel or on our outings. I would take one packet with me everyday while we were out. Just mix with water during a meal break and you ready to go with more energy and focus. With no sugar, you don't get the crash like other energy supplements.

The 4D Clean Energy Dietary Supplement is a quick way to get caffeine and healthy ingredients in a delicious drink. The convenient mix packets are easy to use. I like a stronger mix (16 oz of water to 1 pack). I add it to ice cold water in a shaker flask. I have not had a chance to evaluate the long-term benefits of use yet.

I usually get into a mid day slump and struggle through the second part of the day. Now I drink a bottle of water with my 4D packet around lunchtime and it helps me focus and gives me the drive to push through the afternoon. No jitters or headache. I have the tropical punch flavor and it taste pretty good. The only issue that I have is no matter how much I shake the bottle, I can not get it all to dissolve (you will see in photos). It isn’t so much that I can’t finish the bottle but it may be an issue for someone who can’t handle the grit.

4D Clean Energy Dietary Supplement presents a good option for a pre-workout boost. It is packaged in handy single-serve sleeves, it dissolves well in water and it is pleasant tasting. If anything, it was a bit strong and I watered it down some to mellow-out the flavor. I used 4D prior to a few lifting/biking workouts in recent weeks and it seemed to put a bit of pep in my step and it sat well and didn't cause any stomach upset like some pre-workout supplements I've tried.

It is nice that these come in a single serve tube that makes it easy to have ready quickly. But the aftertaste is pretty bad. I tried this every day for 25 days and really didn’t see any changes that the product suggests. So I got some more but still haven’t seen any results. I was at least hoping for a little energy boost but I have not experienced that.

I have been testing this product the past two weeks while rebuilding 3/4 of a mile of barbed wire fence. I take one before I start and one after. The energy boost it gives me is noticeable and has kept me going even when the temperature was in the upper 90’s. I also take one after I am done for the day to help in my recovery. You will need to mix with 32 ounces of water as the flavor is very strong. The berry flavor is good.

Great product, comes packaged beautifully!! Tastes good, easy to make and the box comes in a nice convenient way to open it. Really does give a boost in energy and helps with pre-workout. Mix 1 full pack with 16-24 ounces of water. Best to consume 30 minutes prior to activity.
