  • 9 Fruit Punch

Really effective pre workout had a crazy pump for 2 hours

  • 8 Fruit Punch

Had a great pump when working out today, I think it was because I took a rest day yesterday and fueled up which left me with a bunch of energy. I was able to focus pretty well, and a pump at the end. It mixed pretty well, I didn't feel any unmixed resin behind. I didn't mind this fruit punch taste as I don't normally care for them due to being the main flavor in everything.

  • 2 Lemonade

The flavor I chose tasted awful & I hope to have better luck with a different flavor. Bad taste with the Lemonade but the effects from it weren't bad. It has a less caffeine than my old pre workout (25mg less) so if you are used to a ton of caffeine on the daily, this is not going to work for you right away until your body adjusts. I like that there aren't a lot of other ingredients in it but that's a personal preference. Not a bad price either.

  • 10 Fruit Punch

This preworkout delivers a nice energy dose and does so without the jitters from other preworkouts I've had I would definitely recommend it.

  • 9 Wild Berry

Great taste and overall great product. Gave me a boost and a great pump. Highly recommend.

  • 10 Fruit Punch

Amazing to pump you up all day feel the fire coursing your blood

  • 10 Wild Berry

I have been using this product for a few weeks now and IM hooked. It doesnt give you jitters and post workout crash. helps you to focus and get a great pump

  • 10 Fruit Punch

Great product! Very clean and no strong crash. Actually had a pretty nice pump as well! Accustomed to very strong preworkouts and I could definitely say I enjoyed the product. Definitely recommend !

  • 8 Fruit Punch

Didn't have the jitters like I do with other pre-workout. Felt like I was able to push through my powerlifting workout on one serving. flavor was good. I would use again


Great product and true to its flavor as long as you don't mess with the recommended water amount. Great energy from this too as it helped me make a bigger leap in weight than when I was other preworkouts.

  • 8 Lemonade

I use this product combine with the RSP BCAA and I like the fact that you don't feel it but you know it's there by the pump you get. Feels natural no jitters no needle like feeling and no crash

  • 8 Fruit Punch

Didnt have the jitters like i do with other preworkout. Felt like i was able to push through my whole workout on one serving. Normally i need two scoops just to have some energy. Great product even my girlfriend liked it.

  • 9 Fruit Punch

I love the fact that this has 300mg of caffeine, more than enough to get through a workout. No jitters or burning sensation either. Definitely would recommend it to anyone looking for a good preworkout.

  • 10 Fruit Punch

I recently received a little sample box which included this preworkout. I LOVED IT! The fruit punch really tasted like normal fruit punch and not chalky or “fake”. It didn’t give me that tingle feeling, even tho I knew it was working, and it helped me push past that fatigue point. I really felt like I could just keep going, I didn’t want to end my workout!

  • 8 Fruit Punch

This pre workout was great, definitely gave me the boost I was looking for out of any pre workout. Not really a fan of fruit punch. But other than that this is great quality. Trained longer and lifted heavier every chance I got with this product.
