12 Hour Energy | Controlled Release Energy Capsules

I purchased this pill on a recommendation by another amazon customer. First off, I am stricken with many ills, and I am relying on 5 hour energy drinks to get me through the day. The problem with that is they are quite pricey. So I am looking for another alternative. Now this supplement has 2 big drawbacks for me- I have an extremely sensitive digestive system, and the Nettle Leaf extract contained in this pill tremendously upsets my stomach. Plus the Yohimbine has caused me coughing fits, as well as immense and severe vomiting. All of these side effects diminish and totally vanish after an hour or 2 of taking it, but they are still too severe for me to continue taking this supplement.Now for the pros, for anyone looking to purchase this. It certainly did last 12 hours, for me anyway. I notice it takes about 10 or so minutes to begin working, and kind of levels out, but around the 8 hour mark, it delivers another burst of energy.As for the final verdict, great energy supplement, but it is not without side effects.

This product is great. What makes it stand out is the controlled release caffeine. No more up and down crash like you would experience drinking coffee or those garbage 5-hour energy shots through out the day. I like to have a couple cups of coffee with one pill when i wake up.A very nice caffeine boost through out the day. People who have a high tolerance to caffeine may want to take two capsules, as one capsule only contains 200mg of caffeine (which would be equivlent to drinking a single Rockstar/Amp/Monster through out the day).These caps are about twice the price as your standard Caffeine pills. However here are some things to consider:1) They are the only controlled release caps on the market that are MADE IN THE USA. Great quality.2)They contain an energy blend (not just caffeine).3) One capsule is about .60 at the current amazon price. Cheaper then an energy drink and lasts longer.I wouldn't take these every day because tolerance can build up, only take as needed. Great addition to your current supplement stack.

They really work. I use to drink 2 energy shots a day to have enough energy to stay awake and get through my day. After a while they just didn't seem to help and it was getting too expensive. I came across these  12 Hour Energy | Controlled Release Energy Capsules  and figured it was worth a try. I am so glad I did. They absolutely work fantastic and are worth every penny. I recently told a friend about them who works various shifts including nightshift and he wanted to try them so this time I ordered 2. I have medical issues that run me down as well as take pain medication which doesn't help. For the first time in years I can get through my day without the overwhelming tiredness I experienced with my medical issues. I would recommend this product to everyone. If it can help me I am sure it could help anyone. Thank you 12 Hour Energy for giving my life back.

I ate one of these early in the morning on an empty stomach. I ate a light breakfast an hour later. I worked a 9-hour shift and went for a 20 mile bike ride after work.

I've tried using a number of energy drinks and energy supplements. The only thing that every really seems to work effectively is 5 Hour Energy. I bought a bottle of this for use before school and work and I've noticed absolutely no difference whatsoever in my energy level and/or how drowsy I am. Save your money.

Actually work very well, very smooth boost. Similar to about 2 mg of Dexedrine.Perhaps also slight boost of libido [noted a recent paper about effect of caffeine on ED].Staff member was also impressed with this product [for maintaining energy on long shift].Some evidence in medical literature that time release caffeine is more physiological than consuming a cup of coffee.

I could not believe how well this product worked - in genuinely lasts ALL DAY.... I took one pill every morning for 30 days and was extremely productive the whole month ... Only thing is when I ran out of these I felt really tired, lazy and had a horrible headache for 3 days! Well, I just won't run out next time!

This product does what it says, It gives you 12 hours of energy, the problem is the type of energy it gives youI took one capsule before I went to work and it made me jittery for 12 hours, felt like I was on caffine overload
