Awesome product

Hey. So I’ve tried preworkout once before in the past but I didn’t have a good experience with it cause it made my body feel super uncomfortable but yours is great. The flavors actually taste like kiwi and strawberry. It tasted really good and felt smooth. I tried half a scoop at first then I did an additional scoop. It worked great, I did some workouts at home, about 160 pushups/other stuff and even cleaned my room and did laundry lol. I never planned on taking preworkout due to my first experience but yours was great. I’m looking forward to making this preworkout part of my routine now. It’s an awesome product 🔥

Great Pre-Workout

I’m really happy with this supplement. The flavor is really good, there were no side effects like jitters, and I felt the energy/pump needed to get me through my weight lifting sets. This will become my go to from now on. Thanks Otakupump!

Amazing formula!

Perfectly formulated pre workout, has become my go too! Would definitely recommend!

Made a repeat customer here

Probably the best flavor I’ve had since all the other brands I’ve had leave a weird after-taste but his one is great! I also feel amazing and perfectly energetic for my workout so I love this!

Honestly, I was never a fan of pre-workout before this. It gave me the jitters and I couldn't sleep even after taking it in the morning. My brother recommended I try this pre-workout and sure enough, this was the one. Even taking half a scoop is all I need to maximize my output in a workout. Now, I can't workout WITHOUT it. It just doesn't feel as satisfying. My muscles crave Otaku Pump AND I MUST FEED THEM.
