Great source for an energy boost, helps me finish those last sets during a longer workout. Love the added focus I have while I’m using DyNO, no crash afterwards is a bonus.

I'm a fan, definitely the way to go for preworkout on a budget. I've started to build a bit of a tolerance to it after about three weeks of use but you can usually feel it when it kicks in. I like the lemonade flavor, tastes like the lemon heads candy

Really improves workout

Very powerful preworkout, not a ton of ingredients but still does the trick! Gives me energy and focus within minutes and lasts throughout my workout. For an added bonus use the RSP Amino 5000 product during your workout to further increase effects and results!

I am a fitness and kickboxing trainer, this is the best product that gives energy and mood, one spoon is enough to spend a great day

I really enjoy this preworkout. It gives me tons of energy when I have absolutely none lol. I’ll take one and a half scoops on leg day and it’s pretty explosive. This is a great product.

I love this stuff! It gives me tons of energy when I’m too tired to workout. The best part is it doesn’t make me jittery like many preworkouts. It also tastes really good and mixes as well. 10/10 will purchase again!

I'm a little bit of a stim freak, If I was going to create a pre-workout...this would be it! Great taste! Great pump! No jitters (disclaimer though...refer back to the first sentence!) The only reason I didn't give it an overall 10 was a little bit of a dissolvability issue. I can't wait to try the other two flavors!

I absolutely love this preworkout. I get amazing pumps allowing me to push through workouts when I’m too tired. It tastes really good and dissolved in water pretty well too. At the end of the day, I deffinetly recommend this product.

First of all, this product tastes great. Actually I would go as far as to say one of the better tasting preworkouts I’ve had. The pumps are really good and allow me to push through a 2 hour lift day. It does make me feel tingly a little bit but not nearly as much as competitive brands. One of the most important things to me and probably my favorite feature is that it does not leave me crashed at the end. Gradual incline, gradual decline. This is a high quality product from RSP and I will be returning!

Good focus support for work outs. Doesn't make you too jittery. All the flavours are good except lemonade. It tastes nothing like lemonade. It's very similar to what room temperature Neocitron tastes like and drinking it takes your mind whirling back to the moments when you're ill. It even has that lingering cordial-eque honey-like mouth feel and flavour that persists long after consumption. Stick with the punch and berry. I might have to throw out the lemonade. I can't see me being able to stomach it for a month.

I drink this before my hockey games and workouts and it works. I do not feel any jitters.
