How do I use Legion Energy Drink?
Drink one can whenever you want a boost — pre-workout, mid-afternoon, or when you need focus. 150 mg caffeine is a moderate dose that works for most people without causing jitters.
How is this different from other energy drinks?
Most energy drinks contain artificial sweeteners, dyes, and either underdosed or hidden active ingredients. Legion's version uses PurCaf® organic caffeine, Suntheanine® L-theanine, Cognizin® citicoline, and taurine at clinically effective doses — all on a fully transparent label with no proprietary blends.
What does the 1:1 caffeine-to-theanine ratio do?
L-theanine balances caffeine's stimulant edge, producing smooth energy and sharp focus without the jitters, anxiety, or crash. The 1:1 ratio is the most researched for balanced cognitive effect.
Can I drink more than one can per day?
Yes, if your total daily caffeine stays within safe limits (generally under 400 mg for healthy adults, or 3–6 mg per kg body weight). Be mindful of caffeine from other sources like coffee, pre-workout, or Peak capsules.
Is Legion Energy Drink keto- or fasting-friendly?
Yes. Zero sugar and only 5 calories per can. Suitable for keto, intermittent fasting, and low-carb diets.

Great product without all the junk!
I have been a religious gym rat for over a year now, and have been rawdogging it for just as long. I hesitated ever doing a pre-workout because of all the added junk in the ingredients. Maintaining a healthy blood glucose is important to me, and so that ruled out most of my options when it came to what I was willing to try. This one however is sweetened with stevia, and has not spiked my glucose. I started out with one scoop and then moved to two scoops about 2 weeks into taking it. I can tell a difference in my energy levels, and how hard I am able to go in a workout, which was the goal, but also it doesnt give me any after-crash and i feel that the energy is sustained throughout the day. I feel more productive overall! I love the tingly feeling when it starts kicking in. The flavor is good as well.

bad
I bought this blueberry-flavored product, but after trying it twice, I couldn't bring myself to eat it again. The remaining portion eventually solidified into a large block, almost as if it had melted. In the end, I had to throw it all away

Deceptive Pricing
I actually think the product is ok. I'd probably give it 3 stars or so. But, as I go to get my next order, I noticed how they marked it up then provided a discount to the same price it has been. So no, it isn't a ""Black Friday Deal"". This is the regular price.

Terrible taste.
It tastes like chemicals. Its a chemical taste with a lacroix level of blueberry taste mainly when you smell it. It also was not good for the workout. Personally, I prefer the pre-workouts that don’t tingle, but just give you the post you need to get through the workout.

New User Review
As someone who has been working out for going on 10 years now. I’ve tried a lot of pre workouts. I’ve been using this one for a few weeks now and love it! It doesn’t give the itch feeling but amps me up in about a 15 minute span. So I recommend taking it as you get to the gym so it’s ready to go after warmup or as you’re driving to the gym! 5/5 stars for me!

Great PreWorkout!
Love this pre workout - we've been using it forever. The watermelon flavor is so far my favorite. The blue raspberry was good but the tiniest bit bland. It doesn't make my stomach hurt, I definitely get itchy but it wears off pretty easily.

Best I’ve had so far
Bro, I had so many different different pre-workouts in my life and this is only one that has me not crashing, it’s stim free and it really makes you feel like you’re on wings as soon as you hit your sets. So freakin worth it!

It’s a Nope
Yuck yuck yuck absolute yuck.. the flavor just isn’t there tastes fake and plasticy not worth it. It was easy to use if you had a good shaker but since I know cheaper brands that make it taste better this one is just not worth it

Not drinkable
I picked this up through Lightning deal and immediately regretted it. I wanted to like this. The flavor of the blue raspberry is bitter with zero flavor coming through. It’s absolutely not palatable. I requested a refund which Amazon granted. I have tired Legion non stim pre workout Arctic flavor which was fine. I’m not sure why blue raspberry tastes so bitter with a strong chemical taste.

Blue raz tastes so bad
This flavor tastes sooo bad. Believe the reviews. Was excited to try it so I mixed it with some water and it literally tasted like mold. I thought the water was bad or something but nope it was the pre workout. Had to ask customer service for a refund because this is going straight to the trash. I’m not picky & understand sometimes pre workouts aren’t going to taste marvelous… but this is so gross it’s hard to deal with!!!

Works great and Pretty Clean!!
I've been using this pre-workout for a while now and I think it strikes the right balance between ""giddy up"" and a fairly clean product. DO NOT TAKE TWO SCOOPS!! I stick to one and that is plenty. This way it runs you about a dollar a scoop and won't put you in the ER. Sometimes it upsets my stomach; you have to time when you eat and when you use this (ie- make sure food is digested a little before using) Highly recommended!

Naturally sweetened preworkout
I can’t drink typical energy drinks anymore due to their use of sucralose - so I am extremely thankful that Legion makes a naturally sweetened preworkout for me that improves my training quality, dissolves nicely in water and tastes great! Thank you again Legion!
