I've been using this product for about two weeks now. I must say hands down one of the best pre-workouts I have used in a long time and I've tried them all from c4 to Jym and I must say this is in a class of its own. I'm super focused, pumps are amazing and no jitters I can take this hit the gym hard for two hours and get home and fall asleep, Unlike most pre workouts where I would have trouble falling asleep this isn't a problem for me when taking this. The wild berry is pretty good and easy drink. Great product so far!!!

This tastes really good and it helps me push through my workout. Definitely top five preworkouts I have tried in a long time. It doesn’t leave me feeling crashed and it’s pretty gradual.

I have been using tangos for the past month. I actually really enjoy this preworkout. Nice pumps and no dumps.

Great pre w/o. No jitters just a boost that really helps wake me up before my workouts after work.

This is an excellent pre workout. I love the beta alanine kick and tingle during my sets. No cliff dive come down afterwards. The lemonade flavor has no aftertaste like some other brands flavors.

First off, I have never taken this supplement alone. I stack it with RSP Pump Boost. I was taking fast fuel (also by RSP) and this stuff is a huge step up from fast fuel! And fast fuel was great as it is! My energy is insane. No jitters or crash. The flavor is on the upper average side. Not bad by any means, but not all that great either. I plan on using this on super heavy days and fast fuel on the lesser days. I don't want that crazy energy when not needed.

I have been taking this preworkout for about a week now. Its been great, noticed a lot more sweat (i'm in the tropics weather) despite air-conditioning at the gym being at full blast and not many people being around the gym. Started with 3/4 scoop and am slowly building my way up to 1 scoop eventually (to test my caffeine tolerance). Now I am in between 3/4 and a full scoop. The main observations are: no noticeable jitters, my heart rate felt normal (even watch monitoring), more sweating than my previous preworkout. I have read the warning labels on this product and after thinking through I have gone ahead to take this preworkout despite a heart condition (that is not induced by caffeine, but had to be on the safe side) and safe to say it's all good so far.

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!
