How Much Caffeine in Redline RTD?
This question gets asked more than any other – and the quick answer is – we don’t exactly know – but we can make a good guess (which is why it’s not in the caffeine database yet).
UPDATE: This item is now in the caffeine database: 250mg of caffeine per 8oz bottle of Redline RTD.
VPX have not given us a precise answer – and to be honest it’s not so much the caffeine that is the issue with Redline – it is the synergy of a whole bunch of other stimulants.
One representative at VPX claimed that Redline RTD had the equivalent to three cups of coffee. We put this at about 250mg of caffeine. However – is this for 4oz or 8oz?
Here’s what we know about VPX Redline RTD
Comes in an 8oz canister shaped bottle and is made with a proprietary blend totalling 579mg:
- Caffeine Anhydrous
- Evoburn (Pure Evodiamine)
- N-acetyl-L-tyrosine
- Guggulsterone E&Z
- Yerba Mate
- Green Tea
- 5-HTP (5-hydroxy-L-tryptophan)
- cAMP (adenosine cyclic 3’5′-monophosphate)
- Vinpocetine
- Yohimbine HCl
Ingredients lists are given in order of quantity and Caffeine Anhydrous (dry caffeine) tops the list. Evodiamine apparently raises core body temperature and invokes a “shivering” response. One study on mice produced this response with a dosage of 1-3mg/kg. So we could guess that the dosage of Evodiamine is around 80mg up. L-Tyrosine is often used in considerably higher dosage (see more about Redline ingredients here).
I would estimate that Redline RTD has about 250mg of caffeine – but – reactions to it are likely to be different to a typical energy drink with that much caffeine. This is due to other CNS stimulants such as Yohimbine.

Straight Redline
The RTD is one thing – but straight Redline is another. Redline has a proprietary blend of 910mg per 5ml serving. Yes – that is 5 milliliters. So it is likely that there is far more than 250mg of caffeine per 5mls.
How big is the bottle? 240mls.
We are talking a minimum of 12,000mg (12 grams) of caffeine in the whole bottle of pure Redline – probably even more.
That ain’t no energy drink.




I tried it today and drank the whole bottle like an idiot. I can’t sleep! I am giggling and you really do sweat and shiver. I recommended it to a friend and said only drink a little at a time with food. It didn’t hurt my stomach like most drinks of it’s type. I don’t think it’s something I could drink all the time. I’d feel like crap! It’s really the best one out there.
I have it and I haven’t tried it yet, it looks like it tastes nasty. Does it make you want to gag? I still got my receipt and taking it back if someone tells me it is nasty.
You know what? I drink it on occasion, FIRST THING IN THE MORNING, and I have had no ill effects. I don’t slam the bottle, maybe because I get the green apple flavored. (They have multiple flavors now)
I do drink it on an empty stomach and by lunchtime I’m starving, mostly because it does it’s job. I think if you use some common sense and don’t drink it at night or all at once, it will still provide the energy you are looking for without the side effects mentioned above.
Drinking responsibly isn’t just for alcohol.
Cylk Reign, people don’t drink this stuff for the taste, that’s for sure. If I wanted a tasty beverage, I’d grab one of the million items out there. The only reason people take this stuff is for the effects of it. If you’ve purchased a bottle of Redline just because you wanted something tasty to drink while playing videos games or just to drink, you should get a refund. Redline simply doesn’t taste good. The only upside to having such small doses (4 ounches being 1 serving) is that I don’t have to drink so much of this terrible-tasting stuff.
Holy freakin heck!
I dated a huge work-out buff/ army guy last summer and he used to swear by Redlines. He would take one and be pumped for hours, not only spending double, ecen triple time in the gym, but spending extra time burning calories in the bed too. I never thought to drink energy drinks or anything of the sort because I slept well and never needed it.
Recently, I’ve picked up 3 jobs. 2 of which are considered full time. On a minimum of 3 consecutive days a week, my schedule is as follows:
7:45am- Wake up and head to the gym
8-9:30- Meet with trainer.
10:30-5:30- work
8pm-4am- bartend in a night club.
…and after crawling into bed well after 5am, i will wake up at 7am and do it again.
Needless to say, redbull and rockstar just weren’t doing it for me anymore so i remembered this Redline drink that made my ex so loopy. I figured, what the hell? I’m desperate.
Wow. the stuff actually tastes amazing, the RTD. Similar to a vitamin water without that “energy drink” taste. It wakes me up and gets me moving without those insane jitters. Yes…people have asked me once or twice if I’m “coked out,” but sometimes it just hypes me up a little more than expected.
the product scares me because it is so powerful, but i have yet to see a negative side effect.
though i do wish i could find the Redline Princess. I can’t find it anywhere.
so i work in a warehouse basically throwing things all day. so i drink at least 2 of these a day ive drank as many as 4 and in the past year ive became a beast(muscle build) id recommend it to any athlete or loser labor worker like me although i dont recommend anyone else drinks as many as me
my worst side effect- occasional diarrhea and/or lack of sleep
just be careful
excellent for sex
I’ve read a couple of posts where the drink has no effect on people and afterwords somebody makes a comment saying that they’re a liar. well it pisses me off because just the other day i chugged a full bottle of this stuff just before work and it had NO effect on me. all i got was a headache which i’m not sure if that was from the drink or not but i didnt feel like it did anything. i actually felt a little more tired and worn out then usual, i actually had to drink some coffee to wake me up half way through my shift and that did a better job. i had eaten 2 hours before i drank the bottle so i had it wasn’t an empty stomach or anything. idk why these idiots are just randomly assuming we’re lying just because our reaction doesnt match the majority of everyone elses.
People, Redline needs to be enjoyed in MODERATION. This stuff is great…by far the best energy drink I have come across. It not only gives me energy but also lifts my overall mood and mental state. One bottle keeps me going all day long at work. I can focus a lot better and be more productive. Moderation is key!
I have been drinking Redline Extreme and all I have have to say is wow! This stuff works so good. I drink one bottle every morning for breakfast and on an empty stomach but it does give me the shakes unless i eat some food before. I have so much energy throught out the day and I lost 10 pounds in 2 weeks also. So I strongly recommend this to anyone who need some extra energy in their day?
I went to a gas station and grabbed a bottle of redline out of the cooler and the guy sold it to me and i’m not even 18!
This stuff has little effect on me. From reading around about redline, a very small percentage of people have the same problem. I have the syrupy concentrate. I’m afraid to take too much at once (since I can probably still suffer averse health effects even if I have high tolerance), so the most I’ve taken in one sitting has been 10 ml. Even with 10ml, I only sweat; no shivers or increase in energy.
Quite disappointing, since I am unable to get a caffeine high from coffee, energy drinks, etc. and I was hoping for this to be able to keep me awake.
i take the reline concentrate and it works awesome for me.. it curves my appetite makes me want to move around and do something and is fun to take. I also sweat like you are supposed to cuz its a thermogenic. Love it!@
I used to wash down the redline pills with the redline rtd’s. Never got any of those weird effects, just the energy.
drink a bottle every morning on the way to work by mid-day im absolutely crazy and i love it, little excercise during the day at work, eat right, i cut weight
with this simple formula
I ate a HUGE meal before I drank half a redline and I was shaking uncontrollably. It was horrible. And now I feel sick to my stomach. I drank it at 7pm and it’s now 3am and I still feel sick. I’m not shaking anymore though, but I definitely cannot sleep. Then I drank it before a dance one time, I danced for a little bit and got sick and exhausted immediately after and could not stop sweating.
oh a few things I forgot to mention. I am 16, 120lbs and a female. My friends and I (same age but male) have shared this a few times and only one of them had a huge amount of energy and he was exhausted shortly after, but did not feel sick. My other friend (also 120lbs) drank half, nothing happened…he actually felt more tired. So he decided to drink the rest, the only thing that happened is he was more talkative. So I do not understand this product at all. And to be honest, I hate it.
Umm, you need to take another look at Redline because the anhydrous caffeine content is clearly labeled per serving on the bottle and the only other sources are green tea and yerba mate which are found in small amounts. No where near 120 grams buddy.
Also keep in mind that there are various different redline drinks although they are generally quite similar.
My son is in the ER because of this crap with heart papatations u can see thru his shirt. Then again he had this. Ain’t worth the ER bill and no insurance he doesn’t have. Doc said his heart was stronger than his and it was stimulants that caused this.
Duh, I had my doctor read ingredients on small bottle, and it she said it had equivalent of two cups of coffee. IF YOU DUMMIES DON’T USUALLY DRINK CAFFIENE THAN STAY AWAY FROM STUFF THAT HAS IT DUH YOUR SO STUPID. SHE TOLD ME WAS ALL HEALTHY STUFF, THIS IS IN THE SMALLEST BOTTLE. AND OF COURSE IF YOU DRINK THINGS THAT SAY HAS 2 OR 3 DOSES IN IT ALL AT ONE TIME WHAT THE HELL YOU THINK WILL HAPPEN. READ THE DAMN LABEL PEOPLE!
