Tastes. Great , intense wirkout throughout , need 2 scoops for intense workout

  • 9 Fruit Punch
  • 4 Lemonade

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.

This preworkout is awesome! Mixed in some EVL Pump Mode to help accelerate it and it works great. Start feeling the effects in about 15 minutes. Great product!

Verified Buyer

I bought all three of these because of the buy 2 get 1 free sale. I’m currently using the lemonade and it has been amazing! One of the best preworkouts I’ve used. The only thing is every time I open the can, the powder makes me sneeze! All in all though, a great product, Highly recommend

Verified Buyer

Very great for focus and energy I’ve tried many preworkouts but this is one of my favorites. Great price too

  • 9 Fruit Punch

I really liked this preworkout. It only actually took me one serving to really feel it work unlike other preworkouts that takes a couple to feel. Taste was ok but I didn’t mind it. All that matters is performance and it worked better than I’d expected it to, my dad loved it as well.


This supplement used to have 400 mg of caffeine and was a thermo pre workout. I'm not sure if I can get enough energy from it because I'm tolerant to 400 mg. So why did they decrease the amount of caffeine?
