5% NutritionKill It Ready-to-Drink High Stim Pre Workout | 400mg Caffeine Energy Drink | Extreme Pump, Endurance, Focus & Hydration | Citrulline, Beta Alanine, Taurine | 12 Oz Bottle (Tropical Punch)

I pretty much always have some sort of pre-workout before going to the gym. I prefer something with beta-alanine in it (I like the tingle, somehow helps to get me going). This drink is packed with energy. I consume a lot of caffeine, but even I was a little wary of 400 mg. However, about halfway through the bottle I felt a surge of energy coming on, so I left it there and started my workout. Got a truly excellent workout in. Drank the second half today and had another great workout. So, for me half the bottle works great, and the nice thing is that's only 6 oz of liquid, so I don't feel it sloshing around as I am trying to exercise. Taste was pretty good considering all the stuff dissolved in it. No issues sleeping after using it in the afternoon either.

The directions might be a bit concerning. It says to consume the whole drink on an empty stomach 30 minutes before training. If you have an average reaction to caffeine I'd recommend trying a bit out first instead of downing the entire thing.The drink is very effective. I did not drink the whole thing in one go, but the bottle I had was very effective at boosting energy level and ability to work. The taste is absurdly sweet and explosive, it's a very strong flavor and might not be for everyone but it doesn't taste bad.Overall it's an effective energy drink with a high amount of everything in it.

my husband doesnt like when pre-workouts have a lot of caffeine as he isn't able to have a fulfilled workout session. he finds that the amount of caffeine in here constricts his blood flow for a proper pump. he drinks a cup of coffee in the morning too so he finds that it's not necessary to have more just to have stimulation in the body for a good workout. he ended up mixing a quarter at a time with his creatine and other power greens to dilute the caffeine. if you dont drink a lot of caffeine or any at all...then he says this isn't bad for on the go.

This has 400mg of Caffeine, which is pretty much the daily limit. This is also 400mg of caffeine at one sitting if drinking it all at once. Compared to a Redbull or cup of Coffee that has roughly 80mg to 90mg of Caffeine. That is just something to be aware of with this product for safety reasons.It has a sweet berry flavor that is a little to sweet for my liking. The product also comes from a well-known supplement brand which is good in that respect.

We ordered this to try before the gym, but ended up trying it when we didn’t go to the gym. A bunch of us tried it, and all of us agreed the flavor was not good at all, it’s sort of like medicine flavor, in that it’s gross.

The 5% Nutrition Kill It Ready-to-Drink High Stim Pre Workout is potent. Took this 30 minutes before working out and had tons of clean energy without stomach upset. The taste is good not great and the price is on point with similar pre workout supplements.

Tastes pretty good. Pretty sweet, but didn't notice any sort of energy boost. If anything, I almost felt like I could go to sleep, but I drank this after a long day's work.
