Energy Drink Reviews
With so many energy drinks on the market, officials and consumers alike are concerned with the amount of caffeine in energy drinks and shots.
This has a lot to do with the reports of the recent deaths that have been blamed on energy beverages.
One of our goals at Caffeine Informer is to educate the consumer about how much caffeine is in the beverages and products that fill the store shelves.
Consumers can go to our Caffeine Database and find the most caffeinated drinks, but because there are a lot of drinks, in varying sizes and caffeine content we’ve made things easier.
Based on caffeine/ounce alone, we list below the most caffeinated energy drinks and energy shots listed in our database.
With the update to this list we now only include RTD energy shots and drinks. Mixins like liquid or powder caffeine products are highly caffeinated but dependent on the user as regards to the amount of caffeine the “created” drink would contain.

Be to check out the real-time updated list of the 15 most caffeinated energy drinks. The list is sorted by caffeine concentration, rather than the overall caffeine amount.
Drink Featured: VPX Redline
VPX Redline used to be #1 with their concentrated VPX Redline Fat Burner. However, this version has since been taken off the market.
The below account is based on The Original Redline which was a 240 ml concentrated liquid.
Redline now distributes Redline RTD, Redline Extreme, Redline Princess, and Redline Power Rush some of which are listed above.
All of these new versions contain the original formula but watered down.
Historical review of VPX Redline Fat Burner
One of the most powerful energy drinks is called VPX Redline Fat Burner. Amazon is lacking a little information, so here’s a little more:
Check out this freaky scientific VPX breakthrough: RED LINE®: is the only matrix ever developed to shred fat through the shivering response in the body. By shivering the body burns huge amounts of stored body fat for energy in an effort to keep the body warm. That’s not all! In addition to shivering, you’ll also be sweating up a thermogenic storm. The combined mechanisms of these two processes results in unparalleled fat loss!
What fun. Now, it’s pretty obvious looking at the ingredients that there’s caffeine. But get this: all of the aforementioned goodness and the serving size is FOUR ml. About one-tenth of an ounce. The whole bottle has 240 ml or 60 servings. Basically, a bottle of this, less than the size of a normal can of coke, WILL kill you. This is nothing to be playing around with.
I have friends. Not just normal friends, mind you. The kind of friends that voluntarily live on the streets. The kind of friends who, when drinking, race to forgetting. The kind of friends who take caffeine pills, ephedrine pills, and aspirin.. all at once. One, in particular, drinks and consumes over a gram of caffeine daily, to stave off the headaches. So you know this is a serious review:
oh yeah, it’s definitely 90% caffeine. the aftertaste is unmistakeable. the best part is that since i didn’t have my normal “dose” this morning, I probably won’t actually feel sh*t.
[10 minutes later]
the caffeine kicked in a lot faster than i expected. Though in retrospect, it normally does when it’s in syrup form and tastes like ass.
I feel oddly cold too. Took me a minute to realize that while I still was warm, it was that ‘shiver’ reflex kicking in. It’s a lot like when
you get a chill at the back of your neck, but somewhat continuous.
So what’s in this magical bottle of awesome? Caffeine, Green Tea, Yerba Mate, 5-HTP (5 hydroxy-1-tryptophan), cAMP, Yohimbe, Evodiamine, and Vinpocetine. And a few other things.
I know, I know, so here’s some more info:
cAMP is cyclic adenosine monophosphate. It supposedly “sparks many intercellular processes.” Whatever that means. Increased concentrations supposedly raise thyroid hormone levels and help fat burning (would help explain why it’s in a fat-burning supplement).
Yohimbe is a bark extract from a tree in Africa. It’s considered a natural aphrodisiac and sold here to treat impotency, dilate pupils, and stimulate fat loss. It can also mess with your blood pressure, so watch out.
Evodiamine is derived from some Chinese fruit called Evodia Rutaecarpa. Supposedly burns fat.
Vinpocetine is an alkaloid derived from some periwinkle plant. It is used in Europe, Japan, and Mexico to treat cerebrovascular and cognitive disorders. Some people claim it elevates metabolism, but with no proof.
And the interesting one in the group: 5-HTP. I made sure to spell it out, so the smart ones in the group have already figured out the key: Tryptophan. It’s the same stuff in turkey that makes you sleepy, and there’s scientific evidence of it. The 5-HTP compound is sometimes used to treat mild depression since, somehow, it can increase serotonin levels. It can also affect appetite, which may be part of why they put it in here. The other part? When you’re jacking up a drink with this much caffeine, you’re going to get jitters and “scatterbrain.” This may actually cut the disconnected thoughts out and allow you to think normally, but still, give you the energy effects of caffeine. Awesome.
Apparently, you can buy this stuff at places like Super Supplements, GNC, and even some 7-11s. The concentrate isn’t something you should take a guzzle of. Or even a large sip. If you search on the internet, you can see some people who took the recommended dose and started blacking out towards the end of a workout. Blacking out. 4 milliliters. Damn. There’s also a ready-to-drink version (I would bet that’s the one at 7-11), and half a bottle is all that’s recommended. Pay attention to it. People are comparing the 1/2 bottle to a full hit of ephedra. Unless you’ve done that before and know the effect it has on your body, don’t go doing anything macho with this one.
Just for a poignant measure, look at this review:
I recently purchased the liquid form of redline at a local 7 Eleven store.
It was the first time I have ever drank an energy drink that had such an affect. With in a few minutes, I started to sweat and shake. Being familiar with the effects of narcotics, I must say the feeling felt a lot like cocaine feels.
The most disturbing trait is that my penis shriveled up like I just got out of the icy cold ocean. I can’t help but think that this product will be taken off the market. The effects are too strong for some minors and may not be safe for people on certain medication which are yet to be known.
And this one:
I tried Redline today while heading to work. I am a huge fan of Red Bull & Diet Rockstar. I am 33 years old & in excellent condition.
Having not read the warning label I drank the whole bottle within 5 minutes. Within 10 minutes I was blacking out behind the wheel & shaking uncontrollably. I pulled over at a gas station — I was having difficulty in swallowing and could not stand, breathe or see straight.
I could not even walk for the convulsions. A bystander called the paramedics. Needless to say – my blood pressure was sky high & I thought I was on my way out.
I feel this drink is extremely dangerous & should not be on the market. There needs to be a very visible warning label not to drink the whole bottle for beginners. It has been 5 hours now & I still do not feel normal.
This drink could seriously kill someone if not informed. I am sorry but I will never drink this again nor recommend it to fellow peers.
Highly Caffeinated Energy Drinks Are No Joke
Most of these highly caffeinated energy drinks and shots are designed to be used by people that have built up a tolerance to caffeine and/or people who are using caffeine as a workout performance aid.
They should not be consumed by the general public and definitely kept out of the reach of minors. Always be aware of a drink’s ingredients and your own tolerance/sensitivity to caffeine before consuming any energy supplement you aren’t familiar with.
